Coffee grounds have always been considered a very good fertilizer for the soil. For this reason alone it is a pity if the coffee grounds that are produced every day are thrown into the garbage can and not on the compost. Why is coffee so good for compost?

Coffee grounds are good fertilizer - also for compost

Always put coffee grounds in the compost

Coffee grounds (without additives) should always be composted if you have the opportunity. He

  • enriches the soil with nutrients
  • loosens the substrate
  • feeds earthworms

That is why coffee grounds are ideal for compost

Coffee contains a number of nutrients that are also found in commercial fertilizers:

  • phosphorus
  • potassium
  • nitrogen
  • tannic acid

Nitrogen promotes the formation of leaf green, phosphorus stimulates flower growth and fruit ripening, while potassium strengthens cell structure.

Coffee grounds in the compost are particularly suitable for plants that like slightly acidic soil. Cucumbers, tomatoes and courgettes also appreciate fertilizer made from coffee grounds. Only seedlings you should not provide with this fertilizer.

Fertilize roses with coffee grounds

You don't necessarily have to compost the coffee grounds. You can also just sprinkle it under your roses. Particularly good fertilizer is obtained if you also mix it with banana peels.

Do not compost wet coffee grounds

If coffee grounds are put on the compost too wet, they will mold very quickly. This also applies to the composting of large quantities.

Let the coffee grounds dry out on a plate first so that they become nice and crumbly. Then it can also be better mixed with other materials such as ash, banana peels and other compost materials.

You can also compost paper coffee filters. Of course, other coverings such as capsules must not be put on the compost!

Note PH value

Coffee grounds slightly acidify the soil. Compost with a lot of coffee grounds is therefore not very suitable for plants that don't like it so acidic. However, by adding lime, you can ensure that the soil does not become overly acidic.

Check the pH of your soil by having a soil sample tested by a lab. Then you are on the safe side.
