August can go three weeks without rain here, and a Tuckerton lawn on sandy ground will tell you about it by the second one. GreenScape Irrigation LLC sets its clocks for first light, when the air is still cool off the bay and water soaks in instead of burning off. Zones balanced, heads aimed, the run times tuned to what the grass is actually asking for rather than a guess. When the first hard cold comes in off the water the system gets blown out and put to bed; in spring it wakes up tested, head by head. Green through a dry August is not luck — it is a valve opening at the right hour.
