Mulching With Coffee Grounds
Mulching is an effective practice in gardening as it helps retain moisture in the soil, suppress weed growth, and regulate soil temperature. Coffee grounds can be an excellent option for mulching, as they offer many of these benefits and more.
To use coffee grounds as mulch, first, ensure that the soil is properly watered. Then, apply a layer of coffee grounds around the base of your plants, ensuring the layer is about an inch thick. Ensure the coffee grounds do not directly touch the plant stems, as this could promote rot. After applying the coffee grounds, lightly water the area to help them settle into the soil.
Coffee grounds, being dark in color, absorb sunlight and help warm the soil. This is particularly beneficial in cooler climates or during the early spring when temperatures are still low. Additionally, coffee grounds act as a natural weed suppressant by creating a barrier that inhibits weed growth. This saves you time and effort by reducing the need for frequent weeding.
Benefits of using coffee grounds as mulch:
- Retains moisture in the soil
