Brown/dead patches, thinning grass, or visible lawn pests/grubs

Likely cause

A fungal disease, grub infestation, or a watering/mowing-schedule issue.

What to try first

• Tug on the dead patch — if the grass lifts up easily like carpet with no roots, that points to grubs, not disease.
• Note if the pattern is circular/spreading (often fungal) vs. scattered (often watering or pet damage) — helps the pro diagnose faster.
