  1. Carrots, radishes, wild strawberries, gooseberries, maidenhair fern, lily, blueberries, hydrangeas, rhododendrons, parsley, pepper, and other vegetables and herbs

Another advantage of acidic soil is the ability to grow certain plants, such as the acacia. Coffee grounds, on the other hand, are first diluted with water to make them neutral before being used in regular plants. As a result of the acidity, the regular plants may suffer. There is a significant quantity of caffeine in the unbrewed ground. A plant’s growth is hampered as a result of this. As a result, the decaffeinated ground is the best option for most plants in general. It should be remembered that neutralized fertilizers should not be used in place of water, but rather as a liquid fertilizer.

Which is beneficial to the plants.

Root crops such as carrots and radishes are among those that benefit from the addition of coffee grinds.

It has been discovered that used coffee contains certain allopathic qualities that inhibit the development of tomatoes.

Which Plants Do Not Like Coffee Grounds? (5 Popular Plants)

Coffee grinds are quickly gaining popularity as a composting material. Nitrogen is provided by coffee grounds, which is essential for the growth of nearly all plants. Although this nitrogen-rich compost is beneficial to many plants, not all of them will benefit from it for various reasons. Which plants, on the other hand, do not care for coffee grounds? Flowers such as lavender, orchids, and pothos will not benefit from the use of coffee grinds. Continue reading as we cover some of the plants that do not tolerate coffee grounds, as well as some of the plants that may benefit from the use of coffee grounds.

Is It OK To Add Coffee Grounds to Fertilizer?

Yes, as long as the plant will benefit from the coffee grounds being used. The addition of coffee grounds to fertilizer will improve the soil’s ability to retain water, despite the fact that its acidity has been somewhat raised.

What is in Coffee Grounds?

We are confident that you are familiar with the term “coffee grounds,” but it is possible that you have never considered coffee grounds as a compost material. As previously said, coffee grounds contain nitrogen, which is a crucial component in the growth of plants and is essential for their survival. Aside from being acidic, coffee grounds have a bitter taste. The addition of coffee grounds to your soil raises the acidity level, which in turn changes the pH of the soil in your garden. Increasing the acidity of the soil or changing the pH level of the soil may be beneficial to some crops while being detrimental to others.

In soils that already have a high degree of acidity, you don’t want to add any additional acid to them.

Which Plants Do Not Like Coffee Grounds?

The soil acidity of coffee grounds is ideal for growing plants such as roses and blueberries. Other plants that flourish in acidic soil include azaleas, hydrangeas, rosemary, carrots, radishes, and rhododendrons. These conditions do not apply to plants that dislike acidic soil such as lavender, orchids, and pothos, which grow best in alkaline soil. Now, let’s talk about certain plants that don’t benefit from the addition of coffee grounds. These include:

1. Lavender

Growing lavender plants in full sun requires a climate with high humidity, a sandy soil with little acidity, and soil that is not acidic. As a result, the addition of coffee grinds to this lovely plant will have no beneficial effect on the plant. Growing lavender on soil with a high amount of acidity will inhibit the plant’s ability to thrive. If you discover that your lavender soil is acidic, you may amend it with lime, which will finally lower the acidity level of the soil and raise the alkalinity level of the soil.

Lavenders grow on soil that is alkaline. In tiny containers with around two centers, lavender may be cultivated successfully. Larger species of lavender, on the other hand, will require pots with three-foot centers or more. Check to see that the container has drainage holes on the bottom.

2. Orchids

Remember that we previously stated that coffee contains nitrogen, which may aid in the development of healthy growth in various plants. Orchids, on the other hand, are exempt from this because they lack the microbes necessary to break down the nitrogen in coffee. Mulching with coffee grounds, which may be beneficial for certain plants such as roses, is detrimental to orchids’ growth. Mulching orchids with coffee grounds might result in root rot if done incorrectly. This is due to the fact that orchid roots are unable to absorb nitrogen.

Because of this, there will be breakdown, which will attract gnats and molding.

3. Pothos

Pothos plants are a popular and frequent home plant, mainly due to the fact that they are easy to grow and require little attention. The addition of coffee grinds to pothos will be damaging to the health of this lovely indoor plant. This is due to the fact that pothos does not grow well in acidic soils. However, while pothos may benefit from the nitrogen provided by coffee grounds, the corresponding increase in the acidity of the soil may be detrimental to the plant. But if the soil has a low acidity level, the pothos plant might benefit from the coffee grounds.

A basic pH testing kit may assist you in determining the soil’s pH level.

4. Rosemary

It is possible that rosemary will not benefit from the addition of coffee grounds to its potting soil because it dislikes acidic soil. Although coffee grounds are acidic in nature, you may lower the acidity of the grounds by diluting them with water before using them to water your Rosemary. Rosalina benefits from coffee grounds since they provide critical nutrients that help the plant grow and develop in a healthy manner. The high acidity of the grounds, on the other hand, may prove to be a constraining issue.

5. Cactus

Due to the fact that it is a desert plant, it demands a soil that drains well and has a balanced combination of organic and inorganic minerals. If you use coffee grounds, you may simply modify this balanced mix, which can slow down the rate at which your cactus plant grows. Because coffee grounds contain caffeine, they are detrimental to the development of plants in general and cactus in particular. Caffeine is naturally produced by coffee plants as a competitive mechanism, which permits the coffee plant to establish dominance over its environment.

Which Plants Like Coffee Grounds?

While certain plants may not benefit from the acidic quality of coffee grounds, other plants will require coffee grounds in order to develop and thrive in their environment. Let’s have a look at some of the plants listed below:

1. Sweet Potatoes

When coffee grounds are composted, they provide the maximum benefit. If you’re making coffee compost, the coffee grounds and compost should be mixed in a 1:3 or 1:2 ratio. Instead, you may use an online compost calculator to calculate the appropriate ratio for your particular situation. It is essential to achieve a balanced ratio since you do not want to repress the roots of the plants, which will result in a significant reduction in the number of beneficial soil bacteria.

Coffee grounds can also be used as mulch if they are composted according to the instructions provided here.

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. If you don’t have enough compost, the compost pile will not heat up as it should. 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.

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

Create a barrier to keep slugs and snails out. Because coffee grounds are abrasive, placing a layer of grounds over slug-prone plants may be enough to protect them from these garden pests. However, it should be noted that other studies disagree with this recommendation and believe it is ineffective. If your first plan doesn’t work out, you should have a back-up plan ready. Many cats are put off by the scent of coffee grounds and may avoid using your garden as a litter box if you add coffee grinds into the soil before planting it.

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. If you are utilizing new grounds near pets, exercise caution as your wire terrier may become quite agitated. 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.

It is possible for certain houseplants to thrive if you mix coffee grinds into the soil in which they are planted. While watering your plant, you can even drink a cup of coffee. But, before you start sprinkling coffee grinds on all of your house plants, take a deep breath. Not all plants benefit from the use of coffee. In fact, no plant benefits from the use of large quantities of coffee. Some plants can benefit from the use of a little amount of coffee when watering or from the direct application of coffee grounds to the soil, depending on the variety.

Cyclamen:

Phytochemically, this plant is referred to as Cyclamen persicum. Small, sweet-scented blooms are produced on long stalks that reach beyond the leaves of this diminutive plant. It is a perennial. It is a tuberous perennial, meaning that during the dormant season, it dries down to its thick roots (or tubers), and then grows back during the growth season. It contains blossoms in a variety of colors, including pink, purple, red, and white. It features little heart-shaped leaves with a silver lining that give it a silvery appearance.

Low-maintenance plants that thrive in partial sunlight, cyclamen are an excellent choice.

But it requires a soil that is a little acidic in order to grow properly.

African Violets:

Plants that grow in Africa are known by the scientific name Saintpaulia spp. These are little plants that bloom with stunning royal purple and deep pink blooms in the spring. The brightly colorful blossoms, along with the velvety dark green foliage, can add a splash of color to any setting. During a difficult workday, they may be planted in little pots and placed on your desk to help you feel more positive. These are thought to be finicky plants, but if you get the hang of caring for them, they are rather simple to maintain.

They can thrive in both low and high light, but prefer high light since it allows them to blossom more fully.

Their favorite type of soil is well-draining, somewhat acidic, and nitrogen-rich in nutrients.

If you pour cold, diluted coffee directly into the soil, it will stimulate blossom growth while also improving the general health of the plant, according to research.

Once or twice a year, combine coffee grounds and broken eggshells with the top layer of the soil in which the African violet is growing to provide additional fertilizer to the plant’s growth environment. This mixture is a fantastic natural fertilizer because of its composition.

Peace lilies:

Spathiphyllum is the scientific name for this particular plant. These peace lilies are just too beautiful to be so adaptable! Dark green foliage cover the peace lily plant, which blooms with stunning white blossoms in the spring. This plant is often used as an indoor plant because of its easy-going character and its aesthetic appeal. As an added bonus, it delivers fresh oxygen, making it a pleasure to look at and to think about. Peace lilies require soil that is somewhat acidic, but not excessively acidic.

There are a number of nutrients in coffee grounds that are beneficial to the development and health of peace lily plants.

As an added bonus, when used as a fertilizer, coffee grounds may also assist in the reversing of the leaves on peace lilies, among other things.

Jade:

The Jade plant’s scientific name is Crassula ovata, and it is native to China. It is a fairly common succulent that has gained appeal due to the fact that it requires little upkeep. Because it is a succulent, it is able to hold water in its leaves, reducing the amount of water it requires. It has numerous small leaves and a stem that is irregularly formed, giving it a very lovely plant with a distinct personality. If you want to offer a plant to someone who doesn’t have a green thumb, this is a good choice.

However, if you want to do your jade plant a favor, mixing in some coffee grounds into the soil every 6 to 12 months would make it very happy indeed.

The caffeine in the coffee offers all of the necessary nutrients.

Heartleaf Philodendrons:

That is the scientific name for this plant, which is called Philodendron bipinnatifidum. This plant has been described as “impossibly difficult to kill.” They can tolerate days of neglect, as well as episodes of overwatering and underwatering, as well as the absence of pesticides, and recover their happiness after only a day of pampering and attention. If and when they want maintenance, philodendrons are quite good at communicating with us. If you meet these requirements, the plant will return to its previous splendor.

It must be planted in soil that is well-draining in order to thrive.

Make adjustments to your watering schedule based on the demands of your plants and their location.

The addition of coffee grounds to the soil in which the heartleaf philodendron is growing enhances the fertility of the soil in which the plant is developing.

It also contributes to the solidity and flexibility of the plant’s veins. Furthermore, because coffee grounds are high in organic matter, they are quite good to your philodendron plant.

Golden Pothos

Epipremnum aureum is the scientific name for the goldenpothosis plant. You may use these plants interchangeably with philodendrons because of their striking similarities. These two plants are members of the same family, Araceae, but are members of separate species. The second frequent name for Golden pothos is Devil’s ivy, which means “devil’s vine.” Devil’s ivy can be grown in a pot or in a hanging basket, depending on your preference. Planting it in a hanging basket is preferable since it allows it to grow and fall elegantly on its own, which is more natural.

As long as it receives at least a little natural light, golden pothos may be cultivated in almost every area in the house.

In addition, it helps to maintain the optimal pH necessary by Golden pothos.

Christmas Cactus:

Schlumbergera bridgessii is the scientific name for the Christmas cactus, which grows in the United States. They are so named because of the time of year in which they bloom. They bloom right around the time of the holidays and continue to bloom for several months after that. Just the sight of the pink or lilac blossoms is enough to convince you that this plant belongs on your list of must-have indoor plants. Aside from the lovely flowers, it is very low maintenance and has a lengthy life span with minimal attention paid to it.

As a result, it requires adequate drainage, ample sunlight, and acidic soil, which gets us to the meat of the matter: coffee.

However, because this also includes watering the plant, you should refrain from doing so much longer, or you will cause more harm than good.

Norfolk Island Pine:

Known scientifically as Araucaria heterophylla, this plant is a kind of agave. Technically, it is not a pine tree. Norfolk Island, an Australian external territory in the Pacific Ocean, is home to this plant, which is endemic to the island. They can grow to be quite tall in their natural environment. However, when grown as houseplants, these plants grow like little Christmas trees, with a fully formed canopy and silky needles that feel like silk. These plants have a lengthy life span and can live for several decades if they are given the necessary attention.

Once a week irrigation would be beneficial, and the soil should be allowed to dry out in between watering sessions.

It has the potential to enhance the visual value of any light region of your home.

To grow properly, this plant need the use of acidic soil that drains effectively. It is here that coffee comes into play. Maintaining the acidity of the Norfolk Island Pine requires only one cup of coffee each week to keep it in good health.

Miniature roses:

Miniature roses are actual roses that have been pruned to a smaller size. The same kinds and colors are available in all of the same sizes as their bigger counterparts, and they are in no way weaker or more sensitive than their larger equivalents. In comparison to the larger rose plants, you might consider them to be more difficult to grow. Due to the fact that the larger rose plants are not small enough to fit on a desk, these are typically kept as houseplants. These plants, combined with their attractive, small blossoms, have the ability to completely transform the atmosphere of an office workstation.

Instead of using ordinary water every now and then, you may use coffee grounds as fertilizer in the soil or use prepared and cooled coffee to irrigate the plant instead of regular water.

Snake Plant:

The scientific name for the snake plant is Sansevieria trifasciata, which means “three-headed snake.” This plant is at the top of the list of indoor plants that require the least amount of upkeep. It features sword-like leaves that are green in hue with flashes of yellow on the undersides of the leaves. Because of its easy-going character and capacity to purify the air around it, this plant is a good choice for use as an indoor houseplant. Keeping it alongside your bed will ensure that you have a restful and serene night’s sleep.

It can withstand intense indirect light, but if left in the dark for an extended period of time, the leaves will wilt.

Only irrigate the soil when the weather is hot and dry.

To keep the snake plant happy and healthy, mix two parts coffee with three parts water and sprinkle a little amount of the solution on the soil once every three weeks, according to the directions on the package.

Azalea:

Azaleas are known for producing some of the most beautiful blooms in the plant kingdom. The plant may be found in a variety of hues, including purple, white, pink, yellow, red, and orange. If you enjoy brilliant and vivid colors, this vibrant plant is a must-have in your home. If you want your Azalea to continue to bloom and produce those lovely flowers, you must provide it with the correct care. The majority of Azalea types require virtually complete shade in order to thrive. Some people, on the other hand, require a lot of light.

However, they do not enjoy it when their soil is too acidic, which is sad.

Spider plant:

The scientific name for the spider plant is Chlorophytum comosum, which means “spider plant with a web.” The leaves of this plant are tall and pointed, and they are green with yellow or white variegation. Its leaves stretch out from the center in a manner reminiscent of the fangs of a spider (but not in a nasty way!). With minimal care, it is a low-maintenance indoor plant that gives you with fresh air while also living a long and productive life. The spider plant is an excellent choice for first-time plant enthusiasts since it can withstand a great degree of neglect.

You will not be disappointed with your choice.

Pour one part coffee and three parts water into a spray bottle and spray the solution onto the soil every few days to encourage healthy growth. This plant is great for purifying the air in your room or office since it filters the air around you as you sleep.

Do Indoor Plants Like Coffee Grounds?

Yes, some indoor plants enjoy the smell of coffee grounds, but not all of them do. It is a common misconception that they are beneficial to all types of indoor plants, which is incorrect. Coffee grinds lower the pH of the soil, causing the soil to become somewhat more acidic in nature. They are also a good source of nitrogen as well as various other minerals. Some plants flourish in an acidic climate, while others do not. Coffee grinds are a boon for those plants, as they provide nutrients. In our homes, coffee grounds are a typical source of trash, and they may be recycled to make compost or mulch, as well as pesticides and fertilizers.

It would be beneficial, though, if you utilized it with caution.

However, if they are employed in the proper proportion, they might be beneficial to the plants’ growth.

How Often Should You be Using Coffee Grounds in Your Houseplant?

You may have noticed by now that coffee is high in a variety of micronutrients that may be beneficial to your plant’s growth. On top of that, it is organic fertilizer that you would have thrown out otherwise. As a result, it may be tempting to imagine that the more coffee you provide to your plant, the more successful it will be. (However, unlike you, the plant does not operate on coffee!) Your plants, on the other hand, do not require coffee on a daily basis. So, if you’re going to give your plants the coffee treatment, only do it once or twice a year at the most.

If you intend to use it as a fertilizer, make sure to adhere to the fertilizer treatment plan that has been advised.

However, it might vary based on the time of year and the stage of the plant’s life cycle.

Tips for using coffee grounds on these plants

Taking the unorthodox route requires preparation and foresight on your part. Here are some suggestions for increasing the effectiveness of caffeine consumption in your plants: Combine the coffee grinds with the mulch as follows:

  1. This is a layer of materials such as wood chippings that are put on top of the soil in order to offer nourishment and insulation. Although coffee may be used directly in the soil, combining it with the mulch ensures that nutrients are distributed evenly throughout the soil. If you have energetic pets who like to play with the plant, do not use coffee grounds in the soil to keep the plant healthy. Pets are known to dig their paws into the dirt and consume the coffee in a fun manner. Eating coffee grounds is extremely toxic to pets, and ingesting too much of it can be lethal to them if done in excess. If you have pets, keep the coffee grounds out of the plants and only use a little amount of the coffee grounds. It is a crucial point to remember, and you should not disregard it. Particularly vital when dealing with a tiny or potted plant is the ability to properly water the plant. Just a tablespoon of coffee, or enough to coat the soil with a thin layer of coffee, is more than enough to fertilize your plant
  2. However, more coffee is better. After introducing coffee to the soil, water it down. Thus, you allow for proper mixing of the coffee and mulch with the soil, as well as greater absorption of nutrients from the soil. Coffee grinds should not be used for seedlings. Nitrogen, potassium, and phosphorus are all abundant in coffee beans. The concentration of these nutrients is quite high, making it difficult for a seedling to absorb them. This treatment can be applied after the plants have reached maturity or after they have been replanted. Coffee grinds should be used in a one-to-three ratio. To lessen the potent impact of coffee, combine one part coffee with three parts mulch in a mixing bowl. (Plants, on the other hand, are not as fond of it as humans are!) When coffee grinds are mixed with mulch, the dilution is increased, and the negative effects that may occur if the coffee is utilized directly in the soil are avoided. Always use a coffee filter that has not been bleached while making coffee. You should avoid using bleach around plants (and, to be honest, around oneself)
  3. It is quite toxic.

Conclusion

Here you were, believing that coffee was a personal pick-me-up that you and only you could enjoy. In addition, it has been shown to be useful in improving the mood of some of your favorite plants. (Could there be anything better than coffee?) All of the plants on this list can manage their coffee, but the ones listed above are the most difficult. Avoid making the mistake of putting coffee in all of the plants just because some of them responded positively to it. Including coffee is a great idea, as long as you know when to stop doing so.

Coffee is high in various nutrients that can be beneficial to the growth of some of your plants. In other words, coffee is now a favorite of your plant as well!

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.

  1. Used coffee grounds have a pH ranging from 6.5 to 6.8 when they are delivered.
  2. (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.
  3. Yes, it is a hint of what is to come; continue reading.
  4. 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 popular as using coffee to acidify your soil, is the use of coffee grounds to compost. One studycompared three different composting methods to measure the effect of adding coffee grounds to your compost. In all three methods they found an increase in the death-rate of earthworms. Eeesh, poor little guys! Apparently as the coffee grounds break down, they release “organic compounds and chemicals” which kill the worms. It would appear that coffee grounds are not so great for earthworms after all.

And as if murdering innocent earthworms wasn’t bad enough, it appears thatcoffee has antibacterial properties, too.

If you do decide to add coffee to your compost, do so sparingly.

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?

Unfortunately, depending on the brewing process, this can be true in some cases. An investigation undertaken by the Department of Nutrition, Food Science, and Physiology at the University of Navarra in 2012 found that wasted coffee grounds can contain up to 8.09 mg of caffeine per gram of grounds. Caffeine Informers reports that the study was published in 2012. As a result of these calculations, Caffeine Informer concludes that the typical quantity of coffee grounds needed to make a shot of espresso can still contain up to 41 mg of caffeine, according to the website.

Aha!

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.
