If you drink filtered coffee, don’t throw your coffee grounds away. They are excellent for the garden.
Coffee grounds are a great source of nitrogen, just what your leaves love, though it’s not a quick nitrogen fix. The nitrogen in coffee grounds is released slowly. However, phosphorous (for roots) and potassium (for fruits and flowers) are immediately available.
Coffee grounds will also help to improve the texture of your soil, especially as the worms get to workt. With a pH of about 6.5, coffee grounds are fine for most plants. You can also mix coffee grounds with grass cuttings to form a mulch – on their own they may prevent moisture getting through to the roots of your plants.
