Sprinkle grounds liberally around your plants, or the perimeter of your garden, to deter pests such as ants, slugs, and snails. If you work the grounds deeper into your soil, you'll attract these little garden helpers. Coffee grounds are rich in nitrogen, so they make excellent green matter.

Adding coffee grounds directly to the soil as a fertiliser can be a good option. Coffee grounds are rich in nutrients, especially nitrogen. They also have some amount of other nutrients like potassium and phosphorous. Overall, this means that adding coffee grounds to your garden can work fairly well as a fertiliser.
