Lewis Spencer adds: ‘To use coffee compost, simply sprinkle the grounds directly onto your soil and lightly rake it in. Coffee grounds add organic material to the soil, helping water retention, aeration and drainage. ‘Leftover diluted coffee can create a liquid plant fertilizer, too.

Which plant likes coffee grounds?
While used coffee grounds are only slightly acidic, fresh (unbrewed) coffee grounds have more acid. Your acid-loving plants like hydrangeas, rhododendrons, azaleas, lily of the valley, blueberries, carrots, and radishes can get a boost from fresh grounds.
Which plants do not like coffee grounds?
Coffee grounds are highly acidic, they note, so they should be reserved for acid-loving plants like azaleas and blueberries. And if your soil is already high in nitrogen, the extra boost from coffee grounds could stunt the growth of fruits and flowers.
Can you put coffee grounds straight on the garden?
Adding coffee grounds directly to the soil as a fertiliser can be a good option. Coffee grounds are rich in nutrients, especially nitrogen. They also have some amount of other nutrients like potassium and phosphorous. Overall, this means that adding coffee grounds to your garden can work fairly well as a fertiliser.
Are used coffee grounds good for all plants?
Coffee grounds have a high nitrogen content, along with a few other nutrients plants can use. In most cases, the grounds are too acidic to be used directly on soil, even for acid-loving plants like blueberries, azaleas and hollies.
Can I add coffee grounds to my tomato plants?
Glad to hear coffee grounds are working for your tomato plants! Nevertheless they’re often used on acid-loving plants like azaleas, rhododendrons, blueberries and tomatoes. Be careful, however, not to overload tomatoes with too many coffee grounds. Tomatoes like slightly acidic soil, not overly-acidic soil.
Do roses like coffee grounds?
Roses also love organic material (such as coffee grounds and leaf mulch) added to the soil as this will improve the structure of the soil and feed the ecology of the soil such as earthworms and microbes that break down organic material into a form that is easily taken in by the roses roots.
Can you put coffee grounds in potted plants?
Directly applying coffee grounds to indoor plant soil can cause excessive moisture retention, fungal overgrowth and even impair plant growth. Coffee grounds are a very useful source of nutrients that indoor plants can use effectively, and a very cost effective fertilizer.
Does basil like coffee grounds?
Yes, coffee ground fertilizer is safe for basil and other herbs. Again, just use it sparingly. Herbs definitely benefit from the nitrogen boost that coffee grounds provide.
What can I do with old coffee grounds?
Grinding away: 11 ways to reuse leftover coffee grounds
- Repel garden pests.
- Invite worms.
- Boost compost.
- Fertilise plants.
- Jump start a harvest.
- Make a gardener’s soap.
- Deodorise your fridge.
- Deodorise your hands.
Can I sprinkle coffee grounds on my lawn?
Using coffee grounds as lawn fertilizer is also good for the worms. They love coffee almost as much as we do. The earthworms eat the grounds and in return aerate the lawn with their castings, which breaks up the soil (aerates) and facilitates beneficial microbial activity, further stimulating lawn growth.
Do coffee grounds keep bugs away?
Most bugs have a very strong sense of smell. Since coffee grounds are very potent, it’s a perfect repellent to fight off those pests. All you need to do is place the coffee grounds in a bowl on a flat surface outside, and burn the grounds like you would incense.
Are coffee grounds good for the garden RHS?
Coffee grounds: provides low levels of nutrients and can either be used in small quantities around plants or composted before adding to the garden.
What You Should Know About Used Coffee Grounds For Plants
Whether you are aware of it or not, composting old coffee grounds in your garden is a hotly disputed issue in the gardening community. Some individuals swear by the benefits of using coffee grinds to fertilize plants. However, some believe that is the worst thing you can do for your plants, so whose point of view should you follow? What is the best way to determine if you should – or should not – put old coffee grinds in your garden? We’ve done the research for you, and we’ve broken it down into pros and drawbacks for you so you can make the best decision possible on how to utilize coffee grounds in the garden.
Coffee grounds as mulch
While using mulch in your garden might be beneficial, many people find the expense of mulch to be too expensive when converted into organic matter. Mulch may be made from straw or compost, but not many people have a lot of straw laying around, and compost takes months to make from start to finish. As a result, it appears that coffee grounds would be an excellent mulching material for gardeners in need of mulch. Coffee grounds, on the other hand, can actually injure the roots of seedlings by preventing growth if they are put in excess.
Coffee grinds are little particles that have a propensity to cluster together and create clumps when they come into contact.
So, what is the solution to the problem of utilizing coffee grounds as mulch?
Alternatively, you may rake coffee grounds into the top layer of soil to prevent them from clumping together.
Coffee grounds as fertilizer
Nitrogen, potassium, and phosphorus are all found in high concentrations in coffee grounds, in addition to micronutrients, making the use of coffee grounds as plant mulch a wise decision. Ultimately, the quantity of nutrients in each batch of coffee grounds vary, but coffee grounds may be utilized as a delayed-release fertilizer because of their gradual release. The coffee grounds are not acidic, so there is no need to be concerned about that. Coffee grinds may be used as a fertilizer by sprinkling a thin layer of them onto your soil.
What’s another plus?
Coffee grounds will make your green space a bit more welcoming to worms, so don’t forget to include them!
Coffee grounds in compost
Composting has the potential to be quite useful. Green compost material and brown compost material are the two varieties of compost material available. Due to the fact that they are a green substance, which means they are high in nitrogen, coffee grounds are included in the green category. Typically, the nitrogen content of coffee grounds is roughly 1.45 percent. Food scraps and lawn clippings are examples of other environmentally friendly products. Magnesium, calcium, potassium, and other trace minerals may be found in all of these environmentally friendly products.
If you don’t have any brown compost, you can use some green compost to make some brown compost.
Brown compost material comprises of elements such as newspapers and dried leaves, amongst other things. The usual rule is to have a 4-to-1 ratio of dark compost material to green compost material in your compost pile.
Coffee grounds as a pesticide
Many people also believe that putting spent coffee grounds in their garden beds would help them get rid of slugs and snails that are destroying their plants and flowers. Despite the fact that the reason for this is unclear, whether it is the texture of the coffee grounds that the bugs don’t like or the fact that caffeine is harmful to snails and slugs, the slimy animals tend to avoid coffee grounds at all costs. The same has been speculated about ants as well, however there isn’t much scientific evidence to support this theory.
If it acts as a deterrent for annoying insects in your garden, that’s fantastic.

Coffee Grounds & Gardening: Using Coffee Grounds As Fertilizer
Heather Rhoades contributed to this article. Whether you brew your own cup of coffee every day or have observed that your local coffee shop has begun to throw out bags of old coffee grounds, you may be curious in composting with coffee grounds. Read on to learn more. Is it a good idea to use coffee grinds as fertilizer? What role do coffee grounds have in the success or failure of a garden? Continue reading to find out more about using coffee grinds in gardening.
Composting Coffee Grounds
Composting with coffee is a terrific method to make use of something that would otherwise wind up taking up valuable landfill space in the absence of composting. Coffee grinds may be composted to help increase the amount of nitrogen in your compost pile. Composting coffee grounds is as simple as tossing the spent grinds into your compost pile after they have been used. Coffee filters that have been used can also be composted. You should bear in mind that leftover coffee grounds are considered green compost material and will need to be balanced with the addition of some brown compost material to your compost pile if you plan on adding them to your pile.
Coffee Grounds as Fertilizer
When it comes to using coffee grounds for gardening, the process doesn’t stop with composting. Many people prefer to just sprinkle coffee grinds directly into the soil, where they can act as a fertilizer. It’s important to remember that while coffee grounds will contribute nitrogen to your compost, they will not instantly contribute nitrogen to your soil. When used as a fertilizer, coffee grounds provide organic matter to the soil, which aids in the improvement of drainage, water retention, and aeration in the soil, among other things.
There is a popular belief that coffee grinds reduce the pH (or enhance the acidity level) of the soil, which is beneficial for acid-loving plants.
The acidity of freshly ground coffee grounds is high.
If you rinse your spent coffee grounds, they will have a pH of 6.5, which is close to neutral and will not have an impact on the acidity of the soil.
To use coffee grounds as fertilizer, work the grinds into the soil around your plants with your hands. In this case, leftover diluted coffee works just as well.
Other Uses for Used Coffee Grounds in Gardens
Coffee grinds may be utilized for a variety of different purposes in your garden.
- It is popular among gardeners to utilize used coffee grinds as an amulch for their plants. Coffee grounds may also be used to keep slugs and snails away from plants, which is another application. According to the notion, the caffeine in the coffee grounds has a negative effect on these pests, which causes them to avoid soil where the coffee grounds are present. In addition, some people believe that putting coffee grounds on the soil would act as a cat repellant and prevent cats from using your flower and vegetable beds as a litter box. Additionally, if you are doingvermicomposting with a worm bin, you may use coffee grinds as worm food. Grains of coffee are a favorite food of worms.
Using Fresh Coffee Grounds
When it comes to utilizing fresh coffee grounds in the garden, we receive a lot of queries. However, while it is not generally suggested, it should not pose an issue in some circumstances.
- Pouring fresh coffee grounds over acid-loving plants such as azaleas, blueberries and lilies can help them grow more vigorously in the summer. Many crops thrive in somewhat acidic soil, while tomatoes, on the other hand, are known to be resistant to the addition of coffee grounds. Radish and carrot root crops, on the other hand, react well to this treatment — particularly when the fertilizer is added to the soil during planting time. Fresh coffee grounds are also regarded to be effective in suppressing weeds due to their allelopathic qualities, which are detrimental to tomato plants when used in this manner. Another reason why it should be taken with caution is because of its toxicity. However, some fungal infections may also be inhibited as a result of this treatment. The use of dry, fresh coffee grounds around plants (and on top of the soil) can help discourage some pests, much as the use of old coffee grounds does. While it does not completely remove them, it appears to be effective in keeping cats, rabbits, and slugs at bay, hence reducing the amount of damage they do in the garden. As previously said, this is believed to be due to the caffeine content
- In order to avoid any negative effects on plants caused by the caffeine included in fresh, unbrewed coffee grounds, you may wish to use decaffeinated coffee or just apply fresh grounds in small amounts to avoid any problems.
It’s only natural for coffee grinds and gardening to go hand in hand. In any case, whether you are composting with coffee grounds or simply utilizing old coffee grounds about the yard, you will discover that coffee may provide your garden with just as much of a pick-me-up as it does for you.

How to Reuse Coffee Grounds in Your Organic Garden
If you brew a cup of coffee every day, you have a fantastic supply of organic matter right at the tip of your fingertips. A variety of factors, including the fact that coffee grounds offer you more energy for weeding and pruning, can make your garden happy. Don’t throw away the grass! You may put them to work right now.
Coffee in Compost
Coffee grinds should be disposed of in your compost container. Brown compost material and green compost material are the two varieties of compost material available. Although your coffee grounds are dark in color, they are classified as green material in compost language, which means they are a substance that is high in nitrogen. Nitrogen content in coffee grounds is roughly 1.45 percent. They also include trace minerals such as magnesium, calcium, potassium, and other trace elements. Food scraps and grass clippings are two more types of green composting ingredients.
But it must be supplemented with brown compost material, which includes dried leaves and newspapers, to achieve the proper balance.
If you have an excessive amount of green stuff in your compost pile, it will begin to smell.
Sarah Crowley’s novel The Spruce
Fertilize With Coffee Grounds
Coffee grinds may be immediately incorporated into the soil of your garden. If you want, you may scrape it into the first couple of inches of soil, or you can simply sprinkle the grinds on top and walk away from it. Coffee grounds will release their nitrogen when consumed in little quantities, particularly when combined with dry ingredients. Due to the fact that used coffee grounds have a pH close to that of water, there should be no need to be concerned about their acidity. Make sure you don’t use too many coffee grounds or that they don’t pile up.
You may also manufacture “tea” out of coffee grounds.
Allow for a few hours or overnight steeping of the “tea.” This combination may be used as a liquid fertilizer for garden and container plants, as well as for other purposes.
It also works well as a foliar feed, which you can apply straight to the leaves and stems of your plants to nourish them. The Spruce Tree Sarah Crowley is a writer and poet.
Feed Your Worms
Coffee grinds should be added to your worm bin once a week or so. Worms are very fond of coffee grounds. Just be careful not to introduce too many at once, since the acidity may create problems for your worms. A cup or two of coffee grounds every week is plenty for a tiny worm bin. When you use earthworms combined with dirt as fertilizer in your garden, they will be more attracted to your garden, in addition to the benefits of utilizing coffee grounds in your worm bin.
Keep the Pests Away
Every week or so, add some coffee grounds to your worm bin. Grease traps are a favorite of worms. Adding too many at once may cause your worms to become ill because of the acidity. For a tiny worm bin, a cup or two of coffee grounds every week is ideal. When you utilize earthworms combined with dirt as fertilizer in your garden, they will be more drawn to your garden, in addition to being attracted by coffee grounds in your worm bin.
Fresh Coffee Grounds for Acid-Loving Plants
Fresh (unbrewed) coffee grounds contain more acid than used (brewed) coffee grounds. Used coffee grounds contain just a minor amount of acid. The addition of freshly ground coffee to your garden will benefit acid-loving plants including hydrangeas, rhododendrons, azaleas, lily of the valley, blueberries, carrots, and radishes. Fresh coffee grounds, on the other hand, are toxic to tomatoes, so keep them clear of that part of the garden. This may be a wonderful use for coffee that has been sitting in your cupboard for a while, or for a sort of coffee that you purchased for visiting guests but isn’t your typical cup of coffee.
Coffee grinds should not be used on seedlings or very young plants since the caffeine might hinder their growth.
Sarah Crowley’s novel The Spruce
Dissenting Research Into Coffee Grounds in the Garden
One study conducted in 2016 discovered that employing leftover coffee grounds in the cultivation of broccoli, leek, radish, viola, and sunflower resulted in inferior growth in all soil types, whether or not extra fertilizer was applied. In addition, the coffee grinds increased the soil’s water holding capacity while decreasing weed growth, which is a positive development. The researchers believe that the worse development was caused by the naturally occurring plant-toxic chemicals found in the coffee grounds.
Gardening 101: How to Use Coffee Grounds in the Garden
Because of our current COVID-19 quarantine, I’ve increased my daily coffee consumption to the point that heaps of coffee grinds now gaze at me from the kitchen counter. After thinking about it for a while, I came up with the following question: What more can I do with this brown material than put it in the garbage can that gets picked up every week? To be sure, it turns out that coffee grounds are composed mostly of free organic matter and contain a significant quantity of nitrogen, in addition to potassium and phosphorus, as well as other critical micronutrients.
So, coffee enthusiasts, please continue reading to learn how to safely use old coffee grinds into your garden: The featured image, taken by Mimi Giboin for Gardenista and taken from the book Homemade Garden Remedies: 5 Natural Solutions for Healthier Soil and Plants, was taken by Mimi Giboin.
Use it like mulch.
From the article Architect Visit: Barbara Chambers at Home in Mill Valley, which was photographed by Liesa Johannssen for Gardenista, you can see the image above. In addition to being beneficial for pest control and soil moisture retention, mulch may also be used to enhance the flavor of your plants. Just remember not to place too much mulch around plants or around sensitive seedlings, as this can cause the mulch to become a thick blanket. For the simple reason that coffee grounds contain caffeine, and certain plants may be more susceptible to this stimulant than others, which might result in young plants experiencing growth inhibition as a result.
Now, if you have a large area to cover—and you don’t consume a lot of coffee—consider collecting some from coffee shops (usually, baristas are eager to give this stuff away for free) and incorporating it into your mixture.
Use it as a slow-release fertilizer.
Plants that thrive in acidic environments, such as rhododendrons, will benefit from a generous covering of coffee grounds. Rhododendrons and Memories of Manderley: A Garden Visit, by Kendra Wilson, is reproduced with permission. The majority of people believe that brewed coffee grounds are acidic, which is correct; nevertheless, the level of acidity can vary greatly. Fresh grounds, on the other hand, have a greater acidity level. This means that you should not rely on wasted grinds to significantly modify the pH of your soil.
Simply sprinkle some coffee grinds onto your soil and either rake or softly scratch it in with your hands to incorporate it.
Another option is to make coffee ground tea.
Allow the “tea” to steep overnight, then use the resulting brew as a liquid plant fertilizer on your plants.
Use it to feed worms.
Above: Starbucks provides free coffee grounds to gardeners in the form of sacks of ground coffee. It has been reported that vermicomposters’ worms are also coffee addicts. Every week, put a cup or so of coffee grounds to their garbage can, and this should be enough to satisfy their cravings. Tip: You may also use paper coffee filters in this recipe.
Use it to deter bad bugs.
Are slugs or snails causing you grief? Make use of leftover coffee grounds to protect plants that are at risk of being nibbled on. Because coffee grounds are inherently abrasive and sharp, soft-bodied creatures avoid harsh surfaces such as coffee grounds. However, you should not rely on this as your primary line of defense.
Use it as a compost companion.
A compost pile near Healdsburg, California, as seen above. Photograph by Mimi Giboin for Gardenista, adapted from the article 10 Things Nobody Tells You About Compost (available on Amazon). Add coffee grounds and old paper filters to your compost pile to help it decompose faster. And while you would believe that this dark item belongs in the brown group, grounds are actually a nitrogen-rich green material, similar to food waste and grass clippings in terms of nitrogen content.
Keep in mind that your compost pile must be well-balanced with a sufficient amount of brown compost material, such as dried leaves and newspaper. Aim for a 4-to-1 ratio of brown to green material in your design.
Use it to keep animals away.
Bonus! Cats, among other species, are repulsed by the smell of coffee. Coffee grounds should be scattered over your garden to discourage them from using it as a litter box. The usage of large amounts of coffee grounds, however, may be dangerous to dogs, and because determining the exact amount is difficult, it’s better to avoid using them in your garden if your furry companion enjoys chewing and eating anything that isn’t securely fastened. Have you been able to properly incorporate coffee grinds into your garden?

When you think of a coffee and garden pairing, you probably picture something along the lines of a nice morning cup while reading the weekend papers in the garden. When it comes to the question of “are coffee grounds healthy for plants?” the answer is an unequivocal “yes”: “using coffee grinds in the garden is helpful to plants.” According to coffee expert Lewis Spencer ofCoffee Direct, used coffee grounds (those left over after using a coffee maker) contain a significant quantity of nitrogen, as well as potassium and phosphate.
‘Because of these characteristics, they are ideal for garden activities such as composting.
Using coffee grounds in the garden
Having demonstrated that coffee grounds are beneficial to plants, we may go on. Indeed, utilizing used coffee grounds is an excellent strategy to decrease waste while also increasing the blossoms on your plants. See how used coffee grounds may benefit your plants by following our expert advice in the section below.
How to use coffee grounds as fertilizer
What if I told you that your coffee grinds may be used to make a slow-release fertilizer? Would you believe it? According to James Gray, the creator of BaristaCo, “I always utilize coffee grinds as fertilizer.” ‘Some types of grinds are too large to be flushed down the toilet, so donating them to your plants is an excellent method to decrease waste.’ ‘To use coffee compost, simply sprinkle the grounds straight into your soil and carefully rake it in,’ says Lewis Spencer. Water retention, aeration, and drainage are all improved by adding organic material to the soil through the use of coffee grounds.
Simple: in a bucket, overnight, combine two cups of freshly brewed coffee grounds with five gallons of cold water.’
How to make compost with used coffee grounds
If you’re looking at how to produce compost, consider using coffee grinds among your supplies. In order for composting to take place properly, scientists have determined that a balance of ‘greens’ and ‘browns’ must be maintained, according to the plant doctors at Patch Plants. ‘Greens’ are nitrogen-rich materials that microorganisms in the soil need for growth and reproduction, whilst ‘browns’ are carbon-rich materials that microorganisms in the soil use to feed them and provide them with energy, respectively.
If you have an excessive amount of green stuff in your compost pile, it will begin to smell (a bi-product of microorganism reproduction is ammonia).
Because they are on the top of the soil and not buried, coffee grinds that are left on the surface and exposed to the air are prone to drying out.
So mix, mix, mix, and then wait.’ If you use a worm bin to practice vermi-composting, coffee grounds are a necessary since worms adore the smell of coffee grounds.
Add a cup of coffee grounds every week to a tiny container to satisfy their caffeine craving. Avoid adding too much at once, since the acidity may have a detrimental influence on your worms’ well-being. Even paper coffee filters can be used in the process.
Which plants like coffee grounds?
Coffee grounds have a variety of vital elements that vary from batch to batch, but they all contain the macronutrients nitrogen, potassium, and phosphorus along with the micronutrients,’ notes Lewis, who is concerned with soil health. Flowers and plants such as carrots, azaleas, camellias, and roses would benefit from the addition of coffee grinds to their soil. Tomatoes, on the other hand, are not fond of the grounds. ‘It appears that all plants will benefit from a coffee compost, given that it is prepared appropriately (4:1) and that it is not just dumped on top of the soil, where it will harden and prevent water from entering the soil,’ explains the plant doctor at Patch Plants.
Are coffee grounds good for hydrangeas?
Your hydrangeas would undoubtedly benefit from the addition of recycled coffee grinds to their soil. hydrangeas thrive on nitrogen, which James Gray explains as follows: ‘Coffee makes the soil more acidic and is filled with nitrogen, which hydrangeas go crazy about, resulting in them becoming very brilliant and vivid.’ Because coffee is essentially a fruit, think about how much nutrients the soil receives from things like fallen apples and berries, as this works in the same manner.’
Are coffee grounds good for grass?
With the addition of coffee grinds to the soil, your grass may become greener – and even longer – than usual. ‘Try mixing them with the soil in your indoor plants, or if you collect a significant quantity, sprinkle them over grassy areas to give them a little growth boost,’ says James Gray. ”
Are coffee grounds good for roses?
Because of their high nitrogen content, spent coffee grounds are excellent growing companions for roses, as they assist in shifting the pH of the soil from neutral to acidic – you can learn more about how to measure the pH of soil in our guide. The high nitrogen concentration of coffee grounds, according to some experts, may really burn and kill plants if they are sprinkled on the soil next to them. Others, however, caution against doing so since the high nitrogen content might actually burn and kill them.
Alternatives include mixing one cup of coffee grounds with one gallon of water per bush and watering the plants with this mixture to ensure that your roses are exceptionally vibrant and gorgeous.
Do coffee grounds deter slugs?
Coffee grounds are an excellent repellant for slugs and snails, not to mention other pests. Simply sprinkle the grounds around the plants that are prone to insects to form a barrier between them. ‘Research has shown that caffeine is helpful in repelling slugs and snails whether applied to plant leaves or the growth media,’ explains Lewis Spencer. This is due to the naturally abrasive qualities of coffee, which lead soft animals to shun harsh surfaces. Ruth Doherty is an interiors writer who has written for a variety of publications, including HomesGardens and Ideal Home, among others.

Using Coffee Grounds In The Garden
In our vegetable garden, we make use of coffee grinds in a variety of applications. Every planting hole is filled with a few tablespoons of ground coffee (along with worm castings, broken egg shells, and compost) when we first start the garden in the spring. This simple mixture aids in the delivery of nutrients straight to the plants as they develop. See this article for more information: Three Important Garden Planting Suggestions However, it may be used for a variety of purposes other than only planting holes.
This accomplishes two important goals.
The nutrients seep through the soil as a result of the wetness, assisting the plants in supplying energy to them through their roots.
Because of their thin skin, slugs are often injured when they creep along the jagged edges of the grounds.
In this way, arranging them around the main stem serves to offer a layer of protection, which in turn helps to keep the plants secure. Despite the fact that it may not be 100 percent effective as a deterrent, every little bit helps in some way!
How To Use Coffee Grounds In Hanging BasketsContainers
Coffee grinds provide a great slow-release fertilizer for planters and hanging baskets, as well as for other containers and containers. In fact, it is one of our best-kept secrets for ensuring that our container plants remain healthy throughout the season. Every few weeks, we add a few tablespoons of coffee grounds to all of our pots and containers, in addition to the worm castings and coffee grounds. This is accomplished by simply sprinkling them on top of the soil in each container or basket.
It allows you to store them simply and without having to worry about them molding.
As they do so, the roots of the plant absorb the chemicals, and the magic happens.

When we plant annuals in our flowerbeds, we utilise our grounds in the same way that we do with our food plants. A few teaspoons of the mixture in each planting hole serves to provide energy to the plants. In addition, it continues to contribute to the soil’s improvement year after year. In addition to providing trace nutrients, the grounds also contribute to the structural improvement of the soil. And that structure is critical for proper drainage as well as for supplying air corridors through which water and nutrients may flow in.
As previously said, every time you water your plants or it rains, the nutrients are washed into the soil.
How To Use Grounds On Perennials, Shrubs and Trees
You guessed it: it’s true. Coffee grounds may also be used to aid in the planting of perennials, shrubs, and bushes. Incorporating wasted grinds into hanging baskets and planters is an excellent method to provide nutrients to your plants at no cost. When planting perennials, a few tablespoons of kelp can assist to improve soil structure and provide nutrients for long-term development. When planting bigger plants or shrubs, we just scatter a few coffee filters and grinds around the planting hole at the same time.
In addition, when the grounds decompose over time, they return nutrients to the roots of the plants.

How To Use Coffee Grounds In The Compost Pile
We employ our coffee grinds on the landscape during the spring, summer, and fall seasons. We use them to power our compost pile, though, during the winter months.

When added to a compost pile, they make a good “green source” addition. Coffee grinds, which are a renewable resource, aid in the rapid heating of the pile. This implies that decomposition will occur more quickly, and more compost will be produced more quickly. Add your filter and grounds and sit back and watch the magic unfold! – Using coffee grounds in your garden and flowerbeds this year, as well as having your finest growing season ever, are both encouraged.

5 Reasons To NEVER Use Coffee Grounds In Your Garden
After a brief search on Google for “using coffee grounds in the garden,” you’ll be inundated with links to publications advising you to keep those used grinds! It is recommended that we place them in the garden in order to encourage the growth of vibrant plants such as azaleas. Slugs are repelled by coffee grounds! Coffee grinds may be added to your compost to promote healthy soil and earthworms. Coffee grinds may be used to grow HUGE plants! Some people even advocate for the use of coffee as a mulch.
(As a coffee enthusiast, I’m already persuaded that coffee has mystical characteristics that can bring me back to life.)
But are coffee groundsreallyall that great for your garden?
When you start searching through Google’s huge list of articles, you’ll see that there is a lot of contradicting information. Instead of being acidic, coffee grounds are in fact non-acidifying. For example, coffee is horrible for your compost; coffee is wonderful for composting.
Because I love you, Rural Sprout readers, I spent a couple of hours sleuthing on the internet to cut through the myth and bring you the truth.
It’s probably best if you take a seat for this. Make a cup of coffee first, though, before you sit down to read. We’re on the verge of falling into the rabbit hole. Here’s what I discovered.
Can coffee grounds acidify your soil?
The most typical gardening recommendation for wasted coffee grounds is to utilize them to acidify your soil, which is perhaps not surprising. It makes sense because everyone knows that coffee has an acidic taste. There are a plethora of low-acid coffee blends available on the market nowadays. Specifically, the question is how acidic are coffee grounds once they’ve been used to make coffee? As it turns out, it’s not very acidic at all. It is stated by the Oregon State University Extension that the acid found in coffee beans is water-soluble.
- Used coffee grounds have a pH ranging from 6.5 to 6.8 when they are delivered.
- (It’s a pH joke, after all.) Sorry, folks, but it appears that this traditional technique is a complete fallacy, as discarded coffee grounds have a pH close to that of water.
- Yes, it is a hint of what is to come; continue reading.
- But hold on a sec.
Aren’t coffee grounds supposed to make good mulch?
Nope, this piece of perennial gardening advice is also a failure. Those pucks of wasted grounds you see at your local coffee shop after they’ve produced your espresso shot? Do you remember what they were used for? Due to their tendency to compress too rapidly, coffee grounds are not an appropriate material for mulching.
Your mulch must be able to breathe in order to allow water and air to enter as well as exit the soil. A significant number of scientists are also interested in the coffee topic, as evidenced by the fact that I discovered various scientific research involving the use of coffee grinds in the garden.
So are coffee grounds useful for making great compost?
Nearly as widespread as the practice of utilizing coffee grinds to acidify soil is the practice of composting coffee grounds. The effect of adding coffee grounds to your compost was investigated in one research, which evaluated three different composting processes to determine the effectiveness of the practice. The researchers discovered an increase in the death rate of earthworms using all three approaches. Oh my goodness, those poor little things! According to reports, when the coffee grounds decompose, they emit “organic compounds and toxins” that kill the worms along their path.
In addition, you require additional earthworms in your soil.
If you put coffee grounds in your compost, instead of adding to the growing microbiota of your compost, you may be destroying beneficial microorganisms.
Despite its green tint, coffee is considered a ‘green’ ingredient, and as such, it must be combined with lots of ‘brown,’ such as dried leaves.
What about using coffee grounds for killing slugs?
In any case, given the fact that coffee is effective at killing creatures, it seems reasonable that the advise to use coffee grounds to kill or repel slugs is correct. This one has a big giant maybe written all over it. A recent experiment by Robert Pavlis of Garden Myths, using slugs and coffee grounds, revealed that the coffee grounds did not even delay the slugs’ movement. I’ve seen other anecdotal reports that slugs won’t even venture near coffee grounds, which makes sense to me. In this particular instance, while I cannot say with assurance that coffee grounds will deter slugs, I believe it would be foolish not to try.
That’s right, there’s more foreboding this time.
The1 reason why you shouldn’t put coffee grounds on your plants
You may wonder why it is that I continually reminding you not to put coffee grinds on your plants. For the simple reason that, as we all know, coffee contains caffeine. As much as we would want to believe that caffeine was developed just for humans, nature had different plans. According to science, caffeine was initially discovered as a mutation in plants that was mistakenly replicated and passed on. Caffeine provided an advantage to plants (such as tea plants, cocoa plants, and coffee trees) over competitive plants that grew nearby.
The caffeine in the falling leaves of these plants would “poison” the soil, preventing the growth of other plants in the vicinity.
Many research have shown that caffeine has the effect of suppressing plant development, and this has been proven.
This specific research, in particular, makes me laugh out loud. Applying discarded coffee grounds directly to urban agricultural soils significantly inhibits plant growth, according to the title of the article.
Okay, I’m sure you’re thinking, but I already brewed my coffee, there can’t be that much caffeine left in the spent grounds, right?
For what reason do I have to continually reminding you not to put coffee grinds on your plants? Due to the caffeine content in coffee, which we all know about. No matter how much we’d want to believe that caffeine was designed just for humans, nature had different plans. Coffee, according to science, was initially discovered as a mutation in plants that was mistakenly duplicated and spread across the plant kingdom. In the past, caffeine provided a competitive advantage over surrounding competitors in the form of plants (such as tea plants, cocoa plants, and coffee trees).
When these plants’ leaves fell to the ground, the caffeine in the leaves “poisoned” the soil, making it impossible for other plants to grow nearby.
Many studies have shown that caffeine has the ability to inhibit the development of plants.
This specific research makes me laugh out loud.
It appears we may have finally stumbled across the best use for coffee grounds in the garden – weed killer!
Keep in mind that caffeine has an inhibitory effect on plant development. The International Plant Propagator’s Society performed a research in which they discovered that utilizing coffee grinds resulted in lower germination rates than other methods. The three plants employed in their research were white clover, Palmer amaranth, and perennial rye. The application of coffee grounds to bothersome weeds may be the solution you’ve been looking for to get rid of them. Alternatively, you may boil them to generate a concentrated weed-killing solution.
Even the mound of coffee grounds you threw in the compost bin may be causing you a little nervousness right now.
You’re probably thinking, “What the heck am I going to do with all of those spent coffee grounds now?”
Well, my buddy, I’m happy to tell you that you can put them to good use around the house. I’ve already come up with 28 excellent suggestions for you to consider.

Sounds like a good idea, but do coffee grounds work?
Sarah Hardgrove is a horticultural from Melbourne, and her masters study focused on the impact of discarded coffee grounds on garden plants, which she presented at the Australian Horticultural Society’s annual conference. According to Sarah, “it’s frequently gathered as a resource from coffee shops, and it’s advised that it be planted directly in the garden.” “It appears to be an excellent concept; however, it would be best if the practicalities of composting it were simplified first. Melbourne is known as a coffee-drinking metropolis, and we have an abundance of it.” Sarah conducted her study by setting up an experiment in which she grew radishes, leeks, sunflowers, violas, and broccoli in various soil types, both inside and outdoors, in a glass house.
- The coffee grinds were absorbed into the top 10cm of the soil structure.
- The plants were collected and weighed after about 10 weeks in order to compare growth.
- (Photo courtesy of Sarah Hardgrove) Sarah claims that all of the plants in the study trial suffered as a result of their exposure to coffee grounds.
- We saw essentially the same results across all treatments, including significantly reduced biomass in the plants “she explains.
- They were so insignificant that it seemed foolish to weigh them.” In a glasshouse with coffee grinds added to the soil, seedlings are being raised.
- “We hypothesized that the harmful effects of the grounds and the caffeine were at play,” Sarah explains.
In her words: “Caffeine is a natural defense mechanism utilized by the coffee plant to keep other plants from taking over the plant or animals from devouring it.” As a result, although coffee may help humans to wake up in the morning, it may have the opposite impact on your plants.
A better way to use coffee in the garden
Immediately upon completion of the experiment, the test plots were placed outside to be reclaimed by weeds. Sarah noted an intriguing shift in this area as well, as the plots with greater concentrations of coffee grounds had fewer weeds growing in them than the other plots. According to her, “there was a significant change, practically linear, depending on the proportion of coffee grounds in the soil.” Sarah believes that coffee grinds may still be used in the garden and that they can provide benefits if they are utilized properly.

Coffee Grounds and Composting
Caffeine grounds are a wonderful addition to the garden and compost pile. Contribute to the recycling of this valuable organic resource and the reduction of the quantity of organic waste going to the trash!
Some information about coffee grounds
- In terms of nitrogen content, coffee grinds contain around 2% nitrogen by volume. Grounds are not acidic, and because the acid in coffee is water-soluble, the majority of the acid is found in the coffee itself. Coffee grinds have a pH value that is near to neutral (between 6.5 and 6.8 pH)
- The tilth or structure of the soil is improved by the use of coffee grinds. Coffee grinds are a great source of nitrogen for composting because of their high nitrogen content. They have a carbon to nitrogen ratio of 20 to 1. In informal studies with the Oregon State University/Lane County Extension Service, Compost Specialists documented sustained temperatures of 140 to 160 degrees Fahrenheit for up to two weeks when coffee grinds made up 25 percent of the total volume of the compost pile. Coffee grounds, according to anecdotal evidence, are effective in repelling slugs and snails in the yard.
How do I use coffee grounds?
- Make a layer of coffee grinds right on top of the soil. Cultivate the soil with your hands. After being allowed to dry out, they have the ability to resist water in a manner similar to that of dried peat moss. Leaves or compost or bark mulch can be spread on top of the soil to protect it. By piling the items in the compost pile, you may get the following results: 1/3 leaves, 1/3 fresh grass clippings, and 1/3 coffee grounds. Add coffee grounds to a static compost pile, being sure to always include an equal amount of a carbon source, such as shredded paper or dry leaves, in addition to the coffee grounds. Ensure that everything is nicely combined.
Coffee grinds are not a nitrogen fertilizer in the traditional sense. In a germination test conducted at the GrassRoots Garden in Eugene, Oregon, coffee grounds were combined with potting soil at a 25 percent by volume ratio. The results were encouraging. When compared to lettuce seeds planted in potting mix without coffee grounds, lettuce seedlings put in potting mix with coffee grounds exhibited low germination rates and reduced development. If you are directly adding coffee grinds into the soil, you should also use a nitrogen fertilizer at the same time.
While the microorganisms are working to break down the coffee grounds, the additional nitrogen in the fertilizer will act as a source of nutrients for your plants.
Paper coffee filters may be added to the compost pile to serve as a carbon source.
Coffee grinds do not have a “use by” date.

Using coffee grounds in the garden – fresh and used, for fertilizer or pests
Do you toss away your coffee grounds? That is no longer the case! Coffee grinds may be used in a variety of ways to improve the appearance of your garden and flower beds, just as it does when you drink coffee! It is not only beneficial to your plants, but it also helps to limit the amount of waste that goes to the landfill. Will you continue to toss out your coffee grinds after reading this article? Take a look at these other resources:
- Prepare a soil mix from common home materials
- Learn about the health advantages of coffee
- And learn how to grow mushrooms on coffee grounds.
Used Coffee Grounds in the garden
Coffee grinds may be used for a variety of uses in your garden. In addition to recycling your coffee grounds in the garden, you will actually encourage the growth of plants!
Coffee grounds for fertilizer
Many of us do not have a compost pile or do not have the time to compost in the appropriate manner. As a result, go ahead and just sprinkle coffee grinds straight into the ground! It will not immediately increase the amount of nitrogen in the soil.
Coffee grinds contribute organic matter to the soil during the first step of the process. Drainage, aeration, and water retention are all improved as a result of this. In addition, coffee grounds promote the growth of microbes and earthworms in soil.
- If you are interested in vermicomposting, you may use coffee grounds as worm feeding.
In a second step, microbes that break down the coffee grounds liberate nutrients that were previously locked up in the grounds. A complete family of tiny fungi reduces organic material into bite-sized pieces the size of plants. You may also brew coffee ground tea, which is a wonderful complement to orchid fertilizer because it has no caffeine.
- Using half of a bucket, fill the pail halfway with old grinds
- Fill the pail all the way up with water (soft water if feasible)
- Set aside for 24 hours remove the grounds from the tea and compost them, while retaining the nutrient-dense coffee grounds in the teapot
Once a month during the growth phase, mix one part ground coffee juice with three parts soft water and use it as needed. Keep it refrigerated in a tightly sealed container or bottle.
- Add coffee grounds to batches of weed tea that have been offeredmented. In addition, it will leak nutrients into the mixture.
Coffee grounds for mulch
When used in smaller quantities, spreading layers of coffee grinds asmulchis is useful. The amount of coffee grounds in the mulch mix should not exceed 25 percent (one-fourth) of the total amount of mulch.
- Never stack the coffee grinds in a thick layer if they are pure
- When the tiny particles dry out, they combine to create a watertight barrier. Water cannot reach the earth under the surface of the water unless it is soaked by torrential rains and daylong drizzles. A well-balanced mix should always include additional ingredients such as sand, compost, and normal garden soil. Alternately, let the grinds to air dry. This makes it simple to spray a thin layer of fertilizer on the ground
Additionally, excessive amounts of caffeine present in the ground coffee may have a negative impact on certain plant species. In the presence of an excessive amount of coffee grounds in the soil, plants will develop more slowly or may become stunted until soil organisms are able to break down the coffee grounds.
- In particular, when only pure coffee grinds are utilized to fertilize seedlings, this is true. Coffee grinds will not harm or destroy plants that have been cultivated. In the case of excessive doses, it just takes time for them to recuperate.
Coffee grounds for soil mix
As long as the proportion of coffee grounds in the potting soil mix does not exceed one-fourth (25 percent), you can mix coffee grounds with potting soil mix. These are some of the ways you may utilize this coffee-enriched soil mix:
- Create trays for seedlings and plants to grow in
- Repotted plants
- Transplanted seedlings and plants around your garden
- Prepared the soil for tree and shrub planting
- Big pots and plants should be dressed to the nines
- Coffee grinds can be used as a growth medium for orchids once more. (See previous paragraph.) It has great drainage
- It is little maintenance.
Create trays for seedlings and plants to grow in; repotted plants; transplanted seedlings and plants around your garden; prepared the soil for tree and shrub planting; big pots and plants should be dressed to the nines. Coffee grinds can be used as a growth medium for orchids once more. (See previous section.) Drainage is great in this area.
Garden pests – coffee grounds keep ants, rabbits, slugs and snails away
It is possible to use coffee grinds to prevent your favorite plants from being eaten since caffeine has a bad effect on pests. Typically, dried coffee grounds should be sprinkled over locations where you wish to keep pests at bay. The colony will be forced to leave if it is layered on an ant hill.
- It is important to note that, as with other repellents, it is beneficial to grow “decoy plants” that will attract the pests as well. This may be accomplished by plantingnasturtium in your garden to attract pests away from your roses and other prized plants. Find out more about Nasturtium versus Aphids.
Coffee grounds as a cat repellent
It is important to note that, as with most repellents, it is beneficial to grow “decoy plants” that will attract the pests as well as the repellent. Growingnasturtiums to deter aphids from your roses and other favorite plants is an excellent illustration of this. Read on to find out more about Nasturtium versus Aphids.
- The powerful aroma causes cats to believe that their preferred “number 2” locations have already been polluted.
Used coffee grounds to topdress a lawn
Coffee grinds have a high concentration of nitrogen by nature. This is especially well-suited for use with grass.
- Recycled coffee grounds make an excellent grass topdress. There is no need to combine it with other materials before applying it
Coffee grounds to grow mushrooms
If you are interested in mushroom cultivation, coffee grinds may also be utilized as a substrate for the growth of these fungal species. The grounds are still rich in nutrients, which may be used to cultivate mushrooms, particularly oyster mushrooms, which thrive on spent coffee grounds, according to the manufacturer. By using coffee grounds instead of the more costly substrate, you may save money on the pasteurization process. This is accomplished through the brewing process. All you have to do is complete the following steps:
- Watch your mushrooms develop as you combine the spawn with the coffee grounds.
Because you are utilizing your own coffee waste, as well as that of your neighbors, you are able to obtain your substrate and produce more of your food locally.
Fresh ground coffee
Coffee grounds may also be used in your garden if they are freshly ground. This is coffee that has been ground but has not been used to make a beverage. Coffee that has been sitting about for a while has lost its flavor and must be thrown away. It may be used in the garden!
- Just keep in mind that freshly ground coffee grounds are acidic. used coffee grounds, on the other hand, are neutral. Indeed, the process of preparing coffee transfers the acid to the beverage, and coffee grinds that have been soaked are no longer acidic.
Take note, however, of the fact that freshly ground coffee is acidic. used coffee grounds, on the other hand, have no flavor. Indeed, because the acid is transferred to the drink during the coffee-making process, coffee grinds that have been soaked are no longer acidic
Fresh ground coffee is good for acid-loving plants
You may scatter freshly ground coffee grounds over plants such as:
- Around plants such as: you may sprinkle freshly ground coffee grounds around them.
There are also numerous plants, particularly root crops such as radishes and carrots, that thrive in somewhat acidic soil. All that is required is that you incorporate a little amount of freshly ground coffee into the soil during the planting process.
- Adding coffee grounds to the soil does not improve the growth of tomatoes, on the other hand
Fresh ground coffee to suppress weeds
Adding coffee grinds to the soil does not promote the growth of tomatoes, on the other hand;
Deter pests and other animals with fresh coffee grounds
Fresh coffee grounds, like old coffee grounds, deter pests and animals from getting near your plants and in general from entering into your yard or garden.
How do coffee grounds benefit the garden?
Approximately 2% of the nitrogen in coffee grounds is found in both used and new grounds. When put to your compost, this is really useful. Roasted coffee grounds have a C/N (carbon-nitrogen ratio) of 20, which means that there are approximately 20 parts carbon to one component nitrogen. Acidity is removed from used coffee grounds by any water that is placed in the filter during brewing the cup of coffee. It is important to note that used coffee grinds should have a pH level between 6.5 and 6.8.
Can I put coffee filters in the soil or compost pile?
In contrast to coffee grounds, which are a green compost material, coffee filters, which are a brown compost material, offer an interesting alternative. Simply dispose of them in your compost pile. You can also use coffee that has been packaged in special metal capsules or similar containers. Using a knife on a cutting board, just open them up and pour the grinds into a dish or bucket to collect later.
Coffee grounds are risk-free
Given that coffee grounds have been subjected to the roasting process, they are always considered “good material” for composting and planting beds. Coffee, in contrast to other store-bought fruits and vegetables, is rarely treated with pesticides or other chemicals throughout the growing process. As a result, it may be utilized without having to worry about polluting your garden soil with chemical items.
- In the case of flavored coffee beans, on the other hand, additives are also included in the recipe. Check to discover if the taste is derived from a natural extract or synthetically produced
- The question of whether flavoring degrades in a detrimental manner or not has not been thoroughly investigated.
Where to find coffee grounds for a garden
Although additives are included in the production of flavored coffee beans, they are not necessary. To determine if the taste is an extract from nature or synthetic, look for the following characteristics: It has not been thoroughly investigated if flavoring degrades in a dangerous manner or not.
Large providers of coffee grounds
- Check with the coffee businesses in your neighborhood. Some restaurants now prepare bags of spent coffee grounds for consumers to take home
- Others will do so in the future. A lot of coffee grounds are produced by the coffee machines in Restaurantsoften’s establishments.
You’ll note that many restaurant managers will be pleased to put aside some coffee grinds for you if you ask respectfully (and not during rush hour!).
- To make things even simpler for them, bring anything that can be closed with a lid, such a large plasticware container or a bucket with a lid. Agree on a timetable and follow through with it. If you don’t get rid of the coffee grounds right away, they will begin to mold within three to four days. Because of this, growing mushrooms on coffee grounds is an excellent option. Because there are two containers, it is simple to switch out an empty one for a full one.
Every day, a large number of families make coffee.
Even the tiniest pills add up! One gallon of coffee grounds is produced by an average coffee-drinking family per month.
- Organize a get-together with neighbors. In the event that they do not choose to utilize the grounds themselves, they will be more than delighted to preserve them for you. Why not establish a communal composting facility? Coffee grinds are an excellent “compost material” that can never be acquired in sufficient quantities.
Smart Tip for Used Coffee Grounds
Some individuals mix used coffee grounds into their mushroom soil substrate to make it more palatable. Take a look at these other resources:
- Recycling food waste with poultry
- Collecting rainwater for the garden
- Reclaiming rainwater for the garden
