7 Use leftover coffee grounds to help your garden grow.
Coffee grounds are relatively high in nitrogen, which encourages healthy soil in gardens. They are also a great addition to your compost pile since nitrogen helps turns organic matter into compost. Coffee grounds are especially helpful to acid-loving plants like tomatoes, roses, azaleas and some fruit trees. To fertilize your garden with coffee, mix grounds with water for a liquid fertilizer, sprinkle them around the base of plants, or till them into heavy alkali soil to help encourage earthworms. The only thing to avoid is dumping coffee grounds in clumps since they can mold. Learn more from Fine Gardening and Science Daily.
