Q: Who should I call for Brown patches on lawn in San Jose?

For this problem in San Jose, call a Landscaper.

Irregular brown or dead patches on an otherwise green lawn can be caused by fungal disease (brown patch, dollar spot), grub damage beneath the surface, dog urine burn, compacted soil, sprinkler coverage gaps, or drought stress. The pattern and timing often reveal the cause: circular rings suggest fungus, spongy turf that peels back like carpet indicates grubs, and patches near sidewalks point to heat stress or salt damage. A landscaper can diagnose the root cause, apply targeted fungicide or grub control, adjust irrigation, and reseed or sod the damaged areas to restore a uniform lawn.
