Coffee grounds can be used in the garden and on the farm for so many good things. Here are just a few of them:
1. Sprinkle used grounds around plants before rain or watering, for a slow-release nitrogen.
2. Add to compost piles to increase nitrogen balance. Coffee filters and tea bags break down rapidly during composting.
3. Dilute with water for a gentle, fast-acting liquid fertilizer. Use about a half-pound can of wet grounds in a five-gallon bucket of water; let sit outdoors to achieve ambient temperature.
4. Mix into soil for houseplants or new vegetable beds.
5. Encircle the base of the plant with a coffee and eggshell barrier to repel pests.
6. If you are into vermi-posting, feed a little bit to your worms.
