Coffee grounds are beneficial for plants in multiple ways. They enrich the soil with nitrogen, improving plant growth. Additionally, coffee grounds help in water retention, weed suppression, and attracting earthworms. They’re particularly good for acid-loving plants like tomatoes, roses, and azaleas. However, use them sparingly, as too much can harm plants due to excess acidity. A thin layer mixed into soil or compost works best.
