Overview

• Coffee grounds pack essential nutrients—nitrogen, phosphorus and potassium—that feed tomatoes, cucumbers and other garden plants.
• Both filter coffee grounds and spent coffee pads can be repurposed as fertilizer by home brewers.
• Cooled and thoroughly dried grounds prevent mold and can be mixed directly into soil or watering cans.
• Earthworms gravitate toward coffee residues, improving soil aeration and structure for healthier roots.
• Quarterly applications reduce waste, slash fertilizer bills and cut reliance on chemical alternatives.
