Do Pothos Like Coffee Grounds?

When you are taking care of your pothos you’re probably contemplating other ways to keep it healthier and more productive. You may have heard of coffee grounds assisting in the growth of your pothos, but aren’t certain if this really is logical.

Coffee is a great organic source of pothos-related nutrients. It is a rich source of macronutrients as well as micronutrients that help improve soil structure, regulates soil temperature, and also adds the humic components. Compost tea made of coffee grounds is a great fertilizer for the growth of pothos. Additionally, coffee grounds can help regulate the pH of soil.

If you continue reading you will discover the advantages of this item as an organic fertilizer. The science and facts of coffee grounds will be awe-inspiring to you.

Are Coffee Grounds Good for Pothos?

The answer is yes and the answer is no. It all is dependent on the circumstances. Coffee grounds aid in increasing the acidity of soil.

This is why it’s ideal for soils with an elevated pH. But, it could be harmful for plants if the soil is acidic within it.

How to Test the Soil’s Acidity

The test kit used to determine the the pH of soil is costly and is not widely available. If this is the case, I’ve found a solution.

  • Take soil samples of your mix of potting.
  • Make a container in which you can put the soil and half a cup of water, as well as 1/2 cup baking soda.
  • Place the soil into the container.
  • Mix in 1 cup baking soda.
  • Examine the reaction.

If the mixture bubbles or flashes, it’s an obvious indicator that your soil is acidic. Baking soda can be described as an alkaline chemical. This is why soil that is acidic reacts.

However, you shouldn’t be concerned about it too about it. Pothos can thrive in soils that are acidic. It is even able to compete to maintain the soil’s pH between 6.1 up to 6.5.

But, if the mixture is already at that pH range, then too much could cause the death of the plant.

However, coffee grounds come with a variety of benefits that aid in the development the plant.

How Much Coffee Grounds Should You Add to Your Pothos?

When you add fertiliser to plants, it is crucial to pay attention to the amount of soil. This is especially true for coffee grounds.

The addition of too much coffee grounds over the soil could hold in moisture, which can cause the growth of fungi and other plant illnesses.

This is the reason you have to use a small amount, which is 1/2 inch or a small coating of ground coffee. Then , cover the coffee grounds with a 4-inch layer mulch.

Another method of using coffee grounds to make the soil mix you make with pothos is to add it to the compost first.

Because they have an enthalpy of carbon-nitrogen in the range of 20-24:1, they are an ideal addition to your compost.

Earthworms and other microorganisms are able to consume all coffee grounds faster than other composting substances.

To create an even compost it is recommended to only add 20 % of the coffee grinds in the compost heap.

How Often Should I Put Coffee Grounds on My Pothos?

Coffee Grounds as Fertilizer

Utilize the coffee grounds similar like you would normally use fertilizers. Apply it every 2 to three months. For drinking coffee in liquid form, the best time to apply it is every 2 to 3 weeks.

Pest Control Measure

Coffee grounds can be used to get rid of the pest. Sprinkle coffee grounds over the soil’s surface when you notice the insects emerging.

Best Way to Use Coffee Ground on Pothos

The great aspect of the coffee ground is you are able to utilize it in a variety of ways. It can be used as a fertilizer or compost material as well as a pest control measure and much more.

Here are the most effective methods of applying coffee grounds to pothos:

Composting using coffee Grounds

There’s around 2% of nitrogen in the coffee grounds. Nitrogen aids compost in its ability in breaking down material more quickly.

But, remember that you must include brown compost in order to ensure that the compost is balanced.

In the case of filters for coffee the filter will decompose easily. Therefore, you can throw them into your compost with no worries.

Coffee Grounds as Organic Fertilizer

Instead of purchasing chemical-based fertilizers to fertilize your pothos plant, you can use organic fertilizers to replace it.

If you enjoy drinking coffee and making it You may have leftover coffee that you could make use of to feed your plants.

Some coffee shops offer used grounds of coffee at no cost. Contact a local shop to receive organic fertilizer for free.

Coffee grounds are an organic addition in your soil. This in turn helps improve drainage, aeration, as well as retention of water.

Don’t Use Coffee Grounds for Seedlings

While coffee grounds are an great alternatives to pothos, they can be more harmful more than good for seeds or seedlings.

They stop the seeds from germinating and growing. Additionally, coffee grounds contain extremely fine particles, which helps them to be a lock.

How to Use Coffee Grounds as Organic Fertilizer

It is possible to sprinkle coffee grounds over the surface of your soil. It’s an inert fertilizer that releases slowly. Therefore, you can expect your pothos to release to release at their own rate.

Mix it with Mulch

The use of coffee grounds for mulch can have benefits and drawbacks. Many gardeners are in agreement about the addition of coffee grounds to compost.

But, they differ regarding placing them directly into the soil.

According to some research that caffeine can harm the growth of plants. Additionally, some seedlings show an sensitivity to caffeine.

The thing you should be wary of is to put coffee grounds over seeds or seedlings. This hinders the growth of your seedling and does not make it work

The use of coffee grounds for mulch is fine, so it is accompanied by organic material such as compost and leaf mold. However the use of coffee grounds on their own could be harmful.

The reason for this is because coffee grounds contain extremely tiny particles. Additionally, they add water to the soil which makes your plant susceptible to diseases and fungi.

How to Use Coffee Grounds as Mulch

Apply a 1/2-inch layer of the coffee grounds on the soil. After that, you can add a 4-inch blanket of mulch. Make use of a rake to prevent the mulch from clumping.

Another option is mixing your coffee beans with compost, or any other organic material. After mixing it, utilize it to mulch the pothos’s soil.

Add Coffee Grounds to The Potting Mix When Repotting

Coffee grounds are naturally occurring. Incorporating them into the potting mix in your pothos can increase the soil’s nutrients.

Simply add 10-20 percent of ground coffee to the soil along with other organic matter.

Coffee Grounds as Compost Tea

Another method of using coffee grounds to fertilize your garden is to make compost tea. This way you can utilize coffee grounds to make a liquid fertilizer instead of sprinkle them on the soil.

How to Create a Compost Tea

There are many ways to make compost tea. The easiest method is making 5 gallons of liquid and 2 cups of used coffee grounds. Mix them and then let the tea soak for a night.

Another method of composting tea is to stuff grounds of coffee into a socks. After that, place it in the bucket, which is filled with 5 gallons of water and let it sit for a couple of days.

Water After Application

After putting coffee grounds to your soil, may be thinking about the ideal time to water your pothos.

This kind of fertilizer is slow-release and dry. This is why it’s recommended to add water to the Pothos in the first 48 hours after application.

When you water, ensure that the water flows through the roots thoroughly. This will stop the plants and soil from drying out too much.

Use Drip Feeding Method

After you’ve made a compost tea, you are able to begin to implement the drip-feeding technique to your plant. There are a variety of methods to create your own self-watering system.

Using Water Bottle

  • Find a water bottle, 2 pieces of lumber (same dimensions), and tape.
  • Tape to secure the wood vertically on the two sides of a water bottle. The bottle should be placed upside down. The timber or stick that comes that comes from the bottle’s mouth must be longer. The sticks should be aligned.
  • Cut off the bottom from the bottle. Do not cut it in whole. You can leave a small amount to allow you to open it and close the top.
  • Place the tea in compost.
  • Close the lid on the bottom.
  • Place your bottle upside-down onto your pothos, then gently turn the bottle’s mouth lid to create drips of tea grounds from coffee.
  • It can take up to a week to flush out the tea compost.

Using Rope

  • Make a bucket and a rope.
  • Pour the compost tea into the bucket.
  • Lift the bucket off the plant.
  • Take the end of the slim rope off the opposite end and then poke it into the soil’s bottom.
  • The other way is to take the rope’s bottom off the opposite side and put it in the top of your bucket. The compost will eventually start drips through the rope, from one side to the other.
  • It could take up to a one week for the tea to be composted. can be able to drain.

Benefits of Coffee Grounds to Your Pothos

The most common benefits from coffee ground that the majority of people are aware of is improving soil acidity and promoting the growth of plants, improving soil tilth, and preventing diseases of plants. (Sources: University of Wyoming)

Here are a few possible benefits that coffee grounds could provide the pothos plant:

It can Bind Pesticide Residue

While the purpose of pesticides is to kill pests and insects however, it may also cause toxic effects to plants.

In turn, it slows plant growth and development. The use of coffee grounds in the soil will stop the spread of pesticide residues.

Coffee Grounds Moderate Soil Temperature

Moderating the temperature of your soil can increase the retention of water in the soil mix. This way you will keep your plants from being overwatered. In addition, it protects the soil from becoming too dryness.

Also you can regulate the water retention with ease.

Coffee Grounds Produce Humic Substances

According to a study, humic substances have their advantages. This includes increasing the fertility and soil structure.

Additionally, it improves the root structure and the uptake of nutrients when you repot the plant with coffee grounds.

Coffee Grounds Improve the Soil Structure

It is possible to turn the soils of the mineral up to 35 percent by sprinkle coffee grounds over the mix.

If you are looking to enhance your soil’s structure in the future or in the long run it is possible to improve the soil’s minerals like magnesium, copper and potassium as well as the phosphorus.

Coffee Grounds Produce Carbon/Nitrogen Ratio of 20-24:1

Compost feedstock is vital to the growth of the pothos. The ratio of carbon to nitrogen is sufficient to help break down compost substances faster.

Balances the Soil’s pH Level

If the soil is excessive alkalinity, ground coffee’s acidity can help to balance pH of the soil making it ideal to plant your pothos.

Coffee Grounds Slowly Release Nitrogen

The thing that differentiates coffee grounds in comparison to other fertilisers is the fact that it releases nitrogen slowly.

The soil microorganisms break down the organic molecules down into simple ions, which makes nitrogen’s slow-releasing component.

Coffee Grounds Contain Nutrients and Micronutrients

The amount of nitrogen within coffee beans is 0.2 percent, whereas the potassium content is 0.6 by volume. The the phosphorus content is 0.06.

In addition to these essential nutrients the coffee grounds contain micronutrients like calcium, copper and magnesium. They also contain boron, magnesium and zinc. These are vital for the pothos to flourish.

Coffee Grounds in Your Soil Keeps Cats Away

If your cat or neighbor’s cat is fond of making use of your garden as a litterbox, then sprinkle grounds of coffee in the soil will help keep them out.

Cats are not a fan of the strong scent of coffee. It’s a cost-effective and pet-safe method.

But, this may not be beneficial for your dog, as the majority of dogs will try to taste all things because they are curious. If this is the case, then be sure that your dog is kept far from the plants.

What are the issues when using the Coffee Grounds in Pothos?

Pothos can tolerate acidic soils However, some issues could occur if you don’t make use of coffee that is ground correctly. These are some of the issues you should be aware of:

Possible Fungal Growth

Because coffee grounds are prone to retaining moisture, they can encourage the growth of fungal species. To stop the possibility of this happening you can include organic matter.

If you’re worried that it will occur, you could use an alternative method. Coffee can be sprinkled on the soil to regulate the amount.

However, on the flip side you could spray your soil and pothos using compost tea. The growth of fungal spores is usually seen when mulching.

Coffee Grounds Can Form a Solid Barrier

Because coffee grounds contain extremely small particles, they may develop similar to clay’s texture. After drying, they will harden and hinder development of seeds as well as seedlings.

This is why it’s important to add organic matter the coffee grounds in case you intend to make use of it as a mulch.

Can Inhibit Growth of Pothos

Coffee grounds could hinder the development of your pothos similar to how they hinder the development of seedlings or seeds.

It is more suitable for older pothos plants, instead of fresh ones. Before you put coffee grounds in the soil of your pothos plant ensure that you are prepared to risk it.

Potential Risks to Pothos

Coffee can benefit people due to its antibacterial ingredients. But, how it has benefited humans could differ from the way it impacts the pothos in your body.

For instance, too many coffee grounds promote microorganism growth. The microorganisms utilize nitrogen to grow and for reproduction, but leave nothing to the pothos.

This is why you should include nitrogen fertilizer in the coffee grounds.

Potential Risk to Soil

The pH requirement for pothos is about 6.1 up to 6.5. If you look at its value at 6.1, it’s on the moderately acidic side.

In this case it is only necessary to use grounds of coffee if the soil’s pH level exceeds the recommended level. If your soil’s pH is too acidic, then the coffee grounds will cause more harm than good.

Drinking water with Leftover Coffee is it possible?

Have you ever experienced a moment when you didn’t take a drink of coffee? If so it would be an expensive mistake to throw the coffee to the trash.

The idea of watering plants using leftover coffee is feasible. However, it is dependent on the kind of plant. For instance the pothos can tolerate soil that is acidic.

Other species like pine-trees, Azales, Siberian iris, rhododendrons and lupines are plants that love acid. Drinking coffee leftovers on them is not an issue.

If you notice that leaves are turning yellow it means that there’s excessive acidity in the soil. Don’t water your plants with coffee leftovers right away.

Key Take-Aways

  • Pothos soil mix’s pH must be in the range of 6.1 to 6.5. If it is below that level, the pothos can tolerate it. Coffee grounds can be used to create soils with an elevated pH.
  • Coffee grounds enhance soil’s structure and are a an excellent compost material as they contain 22% nitrogen per volume.
  • Coffee grounds hinder the development of seedlings and seeds. This is why it is important to be careful not to sprinkle or water coffee grounds around the garden when you plant new plants.
