Learn about the benefits of this method and how to do it correctly. Keeping lawns in good condition, especially on hot days, is a concern for many people. Although some resort to using chemicals to make it grow, there is a natural alternative that has several benefits: sprinkling ground coffee grounds. Coffee is rich in nitrogen, potassium and magnesium, three essential nutrients for healthy, colourful grass growth. In addition, it improves the structure of the soil and attracts microorganisms that help the grass recover more quickly.
The main benefits of using coffee in the garden
- Provides nutrients without chemicals: coffee acts as a mild fertiliser, gradually nourishing the grass and restoring its green colour.
- Improves soil quality: when mixed with the soil, it loosens it, retains moisture better and promotes drainage. Ideal for compacted soils.
- Attracts earthworms: Earthworms are allies in the garden because they aerate the soil and make it more fertile. Coffee attracts them naturally.
- Repels insects and ants: The aroma of coffee acts as a mild repellent against ants, snails, and other insects that often damage the grass.
- Reduces bad odours: Coffee absorbs odours and leaves a pleasant aroma in damp areas of the garden.
This technique helps keep your lawn healthy.
How to apply ground coffee to your lawn: step by step
- Collect used ground coffee and let it dry thoroughly to prevent mould from forming.
- Sprinkle it evenly over the lawn, especially in yellowed or weakened areas.
- Use a soft rake to lightly work it into the lawn.
- Water lightly so that the coffee is absorbed without forming mud.
- Repeat the process every 20 to 30 days, especially in spring and summer.
Where to use it and what precautions to take
Coffee grounds are ideal for areas where the grass has difficulty growing or is yellowed, as well as for areas that get a lot of sun and dry out quickly. Although it is a safe method, it is important to take certain precautions, such as not applying too thick a layer, as this can cause excessive moisture. Avoid using damp or fermented coffee and do not use it more than twice a month, as too much can acidify the soil.
