Coffee grounds are not just a waste product after enjoying a fragrant drink, but also a versatile material with many useful applications. They are rich in organic matter and nutrients, which makes them an excellent fertilizer for plants. Coffee grounds help improve the structure of the soil, adding essential micronutrients such as nitrogen. In addition, they have a slightly acidic nature, which can have a beneficial effect on the growth of some plants, especially those that prefer acidic soil, such as rhododendrons or blueberries.
Another interesting use for coffee grounds is pest control in the garden. Their texture and smell can repel unwanted guests such as ants and slugs.
