Used coffee grounds make an excellent substrate for these gourmet delectables!

Oyster mushrooms are the easiest mushrooms to grow. However, most people grow them on pasteurized straw.

However, if you use coffee grounds to encourage plant growth, when you brew your coffee, you automatically pasteurize your mushroom substrate!

All you need is a container with soil to dump your coffee grounds in and some mushroom spawn to get you started.

Which Plants Do Not Like Coffee Grounds

Coffee grounds are becoming a popular compost material. Coffee grounds provide nitrogen, which is needed in the growth of most plants.

However, not all plants will benefit from this nitrogen-filled compost because of one reason or the other. But which plants do not like coffee grounds? Plants like lavenders, orchids, and pothos will not benefit from coffee grounds.

Read on as we discuss some of these plants that do not like coffee grounds and other plants that might benefit from coffee grounds.

Coffee Grounds Are An Excellent Nitrogen Source For Composting

Coffee grounds are an excellent ingredient for compost too. They have a very special property, on top of being super rich in nitrogen and other nutrients, they also encourage those microorganisms that decompose organic matter.

You only need to sprinkle them over the compost heap, in a thin layer or scatter them. Make sure you dont just lump them in. They work better when they are distributed evenly and thinly.

Coffee Grounds Are Green Compost

No, coffee grounds are dark brown, not green, you may say, but this does not apply to compost colors. Compost colors are based on the two main nutrients we mix in: brown is carbon rich matter while green is nitrogen rich matter.

This is actually true most of the time: if you throw in fresh leaves, they are rich in nitrogen and green if you throw it brown organic matter, you will add lots of carbon.

But coffee grounds are an exception: they are brown in color but rich in nitrogen, so they count as green compost.

This leads us straight into the next point, which is how to use coffee grounds.

How Often Should I Put Coffee Grounds On My Plants

How to Use Coffee Grounds for Plants

Most plants will enjoy up to a weekly dose of coffee grinds on their soil. But all plants are different, and for some, such as cucumbers, its better if they only have coffee grounds every two or three weeks or as needed, which can be determined by the soil makeup.

So, when you start to give your plants coffee grounds, you must introduce them slowly to give your plants time to adjust. Begin by giving your plants a small number of grounds, just a teaspoon or two, every two weeks.

If your plants seem healthy and fine, you can try giving them grounds every week. But if your plants show any signs of illness, such as yellowing leaves, reduce the number of grounds you give them.

You can give your baby plants coffee grounds when you plant them into a pot or the earth for a bit of extra nutritional support. And you can add coffee grounds to mulch too.

Pro tip: If you mix coffee grounds with crushed eggshells then that mixture makes a perfectly balanced N-P-K fertilizer.

However, you shouldnt put coffee grounds on any kind of seedlings because this will stunt their growth. And always be cautious when you scatter coffee grounds in your garden if you have pets. Coffee grounds can be problematic or even poisonous for some animals, including pets like cats and dogs.

Coffee grounds inhibit the growth of some plants due to the caffeine they contain. Some plants also dont like the extra acidity that grounds tend to add to the soil.

Make Alkaline Soil Acidic

Perform a soil test to determine the pH level of the soil. Mix coffee ground and soil with a 35% ground-to-soil ratio. Spread the coffee grounds on the soil. Cover the grounds with bark mulch, compost, or leaves.Till the coffee grounds in the soil are about 6 to 8 inches deep.

This will improve magnesium, phosphorus, potassium, and other nutrients. For every cubic yard of coffee ground, about 10 pounds of slowly-released nitrogen is made available to the plants over the long term.

Plants that like acidic soil will also benefit from the addition of coffee grounds to the soil. Coffee grounds are good for vegetables, including cucumbers, because they enhance tilth and promote microorganism growth.

Pro tip: for the perfect compost, you should have a 4:1 ratio of brown to green organic matter.

If you have vermicompost, the great news is that your worms will love it if you give them used coffee grounds. Worms seem to enjoy the taste of it, and they benefit from having gritty food, such as coffee in their diet. Give your worms a cup of coffee grounds each week, and you can even give them paper coffee filters too.

So How Can Coffee Grounds Be Used Safely In The Garden

The trick is dont use too much in any one place and mix with other materials.

Incorporated with other organic materials, moderate amounts of coffee grounds are useful as mulch and in compost and worm bins.

I regularly take home the waste grounds from our office coffee machine. They are a good source of added humus to the garden and along with the use of gypsum and other types of mulch are gradually improving the quality of my heavy clay soil.

Very fine grounds can become compacted and in dry conditions, they form a water-resistant barrier. For this reason I stir them into the existing mulch or the top layer of soil rather than applying a solid layer of coffee mulch.

In the compost bin, I add them in alternate layers with kitchen scraps and garden waste and add a handful of lime every few weeks. The worms enjoy a helping of coffee too. But dont feed too much at once and add plenty of other material to vary their diet.

Dont add coffee grounds to garden beds were you intend to sow seeds or transplant small seedlings.

On the other hand, you can use the growth inhibiting nature of coffee grounds to slow down weed growth in garden beds that wont be used for six months or more.

To use coffee grounds as fertilizer, simply sprinkle them onto the soil surrounding your plants. Summary Coffee grounds make great fertilizer because they contain several key nutrients required for plant growth. They can also help attract worms and decrease the concentrations of heavy metals in the soil.

Benefits Of Using Coffee Grounds On Houseplants

Apart from helping the environment and saving on costs, the reason it is beneficial to use coffee grounds on plants is quite simple: coffee beans contain nitrogen, which is an important element for growth.

In fact, just about 10% of a coffee bean is nitrogen, which is very important in the germination of seeds. It also affects the growth of plants, including their height, chlorophyll content, and development of the roots.

This points to the benefits of using coffee grounds on your houseplants, especially when they are still young.

The coffee grounds also help to act as mulch, which means that the soil they are mixed with will retain more moisture and the minerals and nutrients have more to cling to. They can also help to keep the temperature of the soil constant.

This sounds like a good thing, which it is for some plants, but there are plants that specifically need looser soil that is well-drained.

These plants would be negatively affected by having coffee grounds in the soil and too much water retained around their roots.

Coffee grounds are also wonderful natural pesticides to use.

Tips For Adding Coffee Grounds To Your Plants

The fact that some plants go well with coffee grounds doesnt mean you should add them mindlessly. Youll want to follow some tips if you want to ensure you gain the desired results.

For coffee composts, you should perfectly adjust the mix ratio to avoid over-acidity. Add coffee grounds to the soil with a recommended ratio of 1:3 or 1:2. Otherwise, you can just use an online compost calculator.

Overuse can result in suppression of the plants roots, a dramatic decrease in soil bacteriasome of which are quite beneficialor trapping the soil worms. So, suiting the compost ratios and amount is pretty important.

When applying, scrub the compost into the soil or at least let it cover the topsoil with a layer of a minimum thickness of 1.5 inches. Also, take care to evenly distribute the compost to avoid aeration blockage in certain areas.

To use the coffee grounds as mulch, you can go through the same procedure but with a few tweaks. After covering the soil, all you have to do is to use wood chips, so they act as organic mulch layers. This will accelerate the soils germination. Such a process is often used while planting soya beans, cabbage, and sugar beet seeds.

Fertilize With Coffee Grounds

Add coffee grounds directly to the soil in your garden. You can scratch it into the top couple inches of soil, or just sprinkle the grounds on top and leave it alone. In smaller amounts, especially when mixed with dry materials, coffee grounds will give up their nitrogen. Used coffee grounds are actually nearly neutral in pH, so they shouldn’t cause concerns about their acidity. Be careful not to use too many coffee grounds or pile them up. The small particles can lock together, creating a water resistant barrier in your garden.

You can also make coffee ground “tea.” Add 2 cups of used coffee grounds to a 5-gallon bucket of water. Let the “tea” steep for a few hours or overnight. You can use this concoction as a liquid fertilizer for garden and container plants. It also makes a great foliar feed you can spray directly on the leaves and stems of your plants.
