Why Does the Peace Lily Benefit from Coffee Grounds?

Houseplants, including peace lilies, have long been known to benefit from the use of used coffee grounds as a natural fertilizer. Permit me to elaborate in case you’ve ever pondered the reason for that phenomenon.


The spent grounds from your coffee are an excellent supply of nitrogen, which is a primary ingredient that many houseplants require. In particular, peace lilies thrive when given a combination of nitrogen, phosphorus, and potassium in their soil. In spite of the fact that you could always utilize fertilizer that was created commercially, why not make use of the coffee grounds that you already have on hand instead?

Organic Matter

Your peace lily’s soil will benefit, not only from the nutrients that are included in coffee grounds but also from the organic compounds that they give. The addition of organic matter to the soil in which your peace lily is growing can be of great assistance since it will increase the amount of aeration available, it will increase the amount of water that will be retained, and it will improve drainage.


The soil that you use for your houseplants can either be acidic or alkaline, which is also known as basic. It is important to understand the distinction between the two since some houseplants may thrive in soil with a higher acidity level while others cannot. The same can be said for soil that possesses higher alkalinity.

Even though coffee grounds have the potential to increase the acidity of your peace lily, not all grounds are effective. Because the acidity of the coffee grounds is stronger, you must add them in without washing them beforehand.

In addition to this, you should incorporate the coffee grounds into the soil as soon as possible instead of waiting a few days (or weeks). The more recently harvested they are, the more acidic they are.

The ideal soil pH for growing peace lilies is between 5.8 – 6.5, which is regarded to be acidic. Therefore, the grounds from your coffee machine are an excellent medium for your peace lily.


Did you know that some types of microorganisms, including earthworms, might really be beneficial to the plant you have in your home? It’s accurate!

They will consume the decaying organic materials when it becomes available to them. Even better, the earthworms’ movement and movement through the soil of your peace lily plant helps to aerate it while they do so.

If you truly do not want to, you do not need to search your garden for earthworms to put in the soil of your plant. You can do this, but it is not necessary. It should only take a small amount of compost in your indoor garden, provided that it is made up of organic materials and fallen leaves, in order to attract earthworms.
