1. 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 turn organic matter into compost. 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. Avoid dumping coffee grounds in clumps since they can mold. Learn more from Fine Gardening and Science Daily.
