Cultural & Environmental Problems - Lawns

Lawn problems are tricky to diagnose. Most turfgrass issues are caused by improper management practices, not by insects or diseases. If you can't find the answer to your lawn problem here, Ask Maryland's Garden Experts. A digital photo can be attached to your question. Also, get advice on pruning, vegetables, insects and much more.
