Do Coffee Grounds Help Against Clover In The Lawn?

Coffee grounds have become an established nitrogen addition in home gardens. The ground beans affect soil texture, making it difficult for clover to become more established.

Coffee grounds: effect

Coffee grounds are not a miracle cure for clover in lawns. Rather, it is a measure to strengthen the lawn and adjust the soil texture to prevent clover from spreading further. This is made possible by the nitrogen released from the coffee grounds to the soil and grass roots. Clover most often occurs in lawns when there is a nitrogen deficiency or the soil is too alkaline. Coffee grounds effectively combat these conditions because in addition to releasing nitrogen, the soil becomes more acidic. The bottom line is that using coffee grounds as a fertilizer would limit clover development in the long run until the soil reaches the desired condition of exhibits. This method should work particularly effectively with the following clover species:

  • ommon horn clover (Lotus corniculatus).
  • White clover (Trifolium repens)
  • Purple clover (Trifolium rubens)
  • Arabian snail clover (Medicago arabica)
  • Yellow sweet clover (Melilotus officinalis)

Note: Do not use coffee grounds when dealing with wood sorrel (Oxalis). Wood sorrel depends on acidic and nitrogenous soils, which would increase the infestation by using the powder.


Essential for the optimal application of coffee grounds against clover is the dosage. Clover species are very persistent and must be controlled over a long period of time to remove them from the lawn.

The correct dosage can only be determined by experimentation. Since coffee grounds are used as fertilizer, you should follow the dosage recommendations below:

  • maximum 50 grams per square meter
  • check lawn a few days after application
  • Adjust dosage depending on the amount of clover
  • Determining the exact dosage is not easy
  • several trials may be necessary

If you want to try coffee grounds against clover, you must apply them correctly. When applying it is especially important. that the coffee grounds are properly incorporated so that they do not lie on the surface of the lawn. Otherwise, the nitrogen cannot be released to the soil.

This is accomplished as follows:

  • do not apply when it is raining
  • spread coffee grounds on the lawn surface
  • work it into the top layer of soil with a rake
  • do not dig up the lawn
  • Water the lawn as usual

Tip: The coffee grounds must dry out completely before application, otherwise mold will form in the lawn. Apply it only cold.
