There is always a stretch in July when the valley goes three weeks without real rain and lawns all over Westwood start to pale from the road edge inward. Rainflow Sprinkler Systems knows that color and works against it — mowing high through the heat so the blades shade their own roots, trimming and edging without scalping the turf, keeping beds mulched to hold whatever moisture is left. A lawn that stays green through a dry August is not luck; it is a hundred small decisions made in the right order. When the rain finally comes back, the grass is ready to use it. That is the ambition in full: green when the block is not.
