Mulch Mulch is straw, tree bark, old hay, yard trimmings or any other organic matter that farmers spread around plants to prevent weeds from growing and to keep vital nutrients in the soil. Mulch creates a wonderful environment for earthworms, which help create healthy soil. It also protects crops from pests and regulates soil moisture and temperature. In many cases, the mulch itself decomposes into rich soil and becomes a long-term fertilizer. | |
