East of town the Diablo hills go gold sometime in May and hold that color until the rains come back, which makes a green lawn at the south end of the bay look like a small act of will. South Bay Lawn Care handles the will part: cutting on a set interval, edging the walks and drives, trimming where the mower cannot go, and feeding and treating weeds so the turf stays thick through the hottest stretch. Cuttings go out with the truck at the end of every visit. In the wet months the schedule holds steady while the grass surges and the whole valley finally matches the yard. A lawn that stays green here is not luck — it is somebody's Tuesday.
