If you’ve noticed small coils or mounds of soil appearing across your lawn, you’re likely looking at worm casts, and while they might not be the prettiest sight, they’re actually a sign of a busy ecosystem beneath your grass. 🍃
Earthworms play an important role in lawn health by helping to improve soil structure and recycle nutrients. However, on closely mown lawns, large numbers of worm casts can become frustrating, especially when they get flattened and spread across the grass.
Here are a few ways to help manage them:
🪱 𝐖𝐚𝐢𝐭 𝐟𝐨𝐫 𝐭𝐡𝐞𝐦 𝐭𝐨 𝐝𝐫𝐲 - Dry worm casts can be brushed away more easily without smearing soil across your lawn.
🍂 𝐊𝐞𝐞𝐩 𝐲𝐨𝐮𝐫 𝐥𝐚𝐰𝐧 𝐜𝐥𝐞𝐚𝐫 - Removing fallen leaves and excess organic matter can help reduce the food source that attracts worms to the surface.
🌱 𝐈𝐦𝐩𝐫𝐨𝐯𝐞 𝐬𝐨𝐢𝐥 𝐜𝐨𝐧𝐝𝐢𝐭𝐢𝐨𝐧𝐬 - Aerating your lawn can help relieve compaction, improve drainage and create healthier growing conditions beneath the surface.
✂️ 𝐀𝐝𝐣𝐮𝐬𝐭 𝐦𝐨𝐰𝐢𝐧𝐠 𝐡𝐚𝐛𝐢𝐭𝐬 - Raising your mowing height slightly during periods of high worm activity can help reduce the impact of casts on your lawn.
Remember, worms are valuable helpers in your garden, the aim isn’t to remove them, but to keep their activity balanced while maintaining a healthy lawn. 🌿
