Americans consume nearly 700 million cups of coffee a day (Zagat 2015), which means we generate a lot of coffee grounds in the process. Putting coffee grounds to use in the garden makes both economic and environmental sense. Many gardeners already use coffee grounds as an essential part of their compost mixture, but an increasing number of people are using them directly as mulch. Speculation abounds that coffee grounds repel cats, kill slugs, prevent weeds, aerate and acidify the soil, provide nitrogen, and attract earthworms. This fact sheet examines the science behind the use of coffee grounds in gardens and landscapes and provides recommendations for home gardeners to use coffee grounds appropriately.
