Gardeners are being urged to sprinkle used coffee grounds on their lawns this April to promote greener, healthier grass. According to specialists at Turf Technologies, the nitrogen and phosphorus in coffee grounds can revitalise turf, making it an eco-friendly alternative to synthetic fertilisers.
Used coffee grounds contain about 2.5% nitrogen, a key nutrient for grass growth. Unlike some artificial fertilisers, the nitrogen is slow-release, feeding the lawn over time without the risk of burning. The grounds also improve soil structure by supporting beneficial microbes, enhancing water retention, nutrient cycling, and drainage.
Earthworms are attracted to coffee grounds, which helps aerate the lawn and boost microbial activity. The experts recommend applying grounds between April and May when grass is actively growing. Simply scatter about a cup per square yard of turf, water gently to help them settle, and reapply every month or two for a “thick, green turf”.
To avoid clumps, spread the grounds evenly using a rake. Let them cool and dry before use. This simple, sustainable practice turns kitchen waste into a valuable lawn treatment.
