How to use coffee grounds as fertilizer

Coffee grounds

We love coffee: More than seven kilograms of coffee beans are consumed in per year on average by one person. In most cases, the resulting coffee grounds will be disposed of without further ado. There is a good reason not to do that: you can continue to use the coffee grounds as fertilizer for your plants!

 Coffee grounds is great as fertilizer

Coffee grounds is a purely herbal product, and it contains relatively many nutrients . For example, coffee beans contain a lot of protein, in which nitrogen, sulfur and phosphorus are collected. While the protein is decomposed by the roasting process and subsequent brewing, many minerals remain in the processed bean powder.

But that’s not all: during roasting, so-called humic acids are produced, which is why the coffee grounds have a slightly acidic pH. Plants that like an acidic humus soil, therefore, are particularly suitable for coffee grounds treatment. These include blueberries, rhododendrons or hydrangeas. 

How to fertilize plants with coffee grounds

Dry coffee grounds before fertilizing! To fertilize your plants with the existing coffee grounds, you should first collect the brown powder in a container. Make sure that the coffee grounds dry well, preferably in a sieve or a plate. Otherwise, mold can form!

Incorporate coffee grounds when fertilizing! After drying spread the powder around the roots. Then you work the coffee grounds in the top layer of soil. If it remains loose on the surface, it can not develop its fertilizing power. To support the effect, cover the fertilized soil layer with a bit of mulch. If you repot your balcony or house plants , you can also enrich the soil with dry coffee grounds.

Be wary for houseplants

When fertilizing house plants with coffee grounds you should be careful, because here the powder can not mix well with the earth and is not decomposed. It threatens mold growth! Therefore, you should first mix the coffee grounds with plant soil and then replace the top layer of earth against the coffee soil.
