Why add coffee grounds to your plant soil?

Coffee grounds make great compost.

They are rich in nitrogen, phosphorus, and potassium. In fact, coffee grounds contain as much or more of these nutrients as manure does.

Coffee grounds have been shown to increase the acidity of soil which is good for plants that prefer acidic soils such as blueberries and azaleas.

A study was done on potted plants that had half their soil replaced with coffee grounds. The results showed that the plants were larger and greener than those left in normal potting soil!

Coffee grounds are great for increasing drainage of your soils which is essential if you water frequently or live in a humid climate. They can be used to make a capillary mat to improve your plant’s growth.

Coffee grounds are also used in hydroponic growing systems because they contain antifungal properties which help prevent mold and bacteria from developing.

Coffee is an organic product, so it contains no chemicals that can harm your plants. There are many ways you can use coffee grounds with your plants.

10 plants that like coffee in their soil


You should add coffee grounds to rose soil because coffee grounds are acidic. Some plants, including roses, require acidic environments in order to thrive.

Coffee grounds have a pH level that is acidic, which will increase the acidity of the soil.

Coffee grounds lower the pH level of soil when they are applied to it, making them a great addition for plants such as acid-loving roses.


Coffee grounds are also great for tomatoes because they add acid to the soil.

Tomatoes prefer a pH level in their soil that is slightly acidic, which makes using coffee grounds an excellent addition.


Blueberries taste great when they are tart and sweet, which is why it’s important to make sure the soil has a pH level that is slightly acidic.

That way, blueberries can grow in an environment where their flavors come out strong.

Like tomatoes and roses, coffee grounds have a pH level of around six or seven, making them another good addition for plants such as blueberries.


Azaleas are another acid-loving plant, so coffee grounds would be a great addition to their soil.

Like with all the other plants mentioned in this post, azalea’s prefer an acidic environment where they can thrive.

Coffee grounds have a pH level of around six or seven that is slightly more acidic than neutral, which makes them perfect for adding to the soil of your azaleas.


Like azaleas, carrots also prefer a slightly acidic environment in their soil.

Carrots prefer an acidity of 6.0 to 6.5, which is relatively close to coffee grounds that have a pH level of around six or seven.

Coffee grounds are not only beneficial because they lower the pH level of soil, but also because they help increase organic material in your garden and make nutrients more accessible.


Acidic soil is also beneficial for radishes, which makes coffee grounds a great addition to their environment.

Coffee grounds can lower the pH level in your garden and give you healthier and more plentiful vegetables.


Cabbage can be used to make coleslaw, sauerkraut, and other dishes.

It’s important for cabbage plants to have soil that is slightly acidic because they love the flavors of an environment where the pH level is around six or seven.

Your used coffee grounds can provide your cabbage with the acidity that it needs to grow!


Rhododendrons are another plant that prefers an acidic environment in their soil.

Like azaleas, rhododendrons thrive when they have a pH level of around six or seven in the soil where they grow.

Coffee grounds will help your plants get closer to the ideal acidity that they need for optimal growth! Who needs fertilizer when you can just use coffee grounds?


Next on the list are hydrangeas. These plants require a pH level of around five or six, which is very acidic.

Coffee grounds contain acids that will help increase the acidity in your soil and make it more suitable for hydrangeas.


Lilies also prefer a slightly acidic environment in their soil, which makes them another good fit for coffee grounds.

Like hydrangeas, lilies do best when the pH level of their soil is around five or six.
