East Norwalk runs out to the water at Calf Pasture, and the soil out that way is sandy enough to drink a July rain and want more again by Thursday. F.Pinho Irrigation and Lawncare LLC works with that ground instead of against it — irrigation kept running through the dry weeks, mowing and trimming on schedule, edges held sharp along walks and driveways, beds cleared when the season turns. Water in the right amount at the right hour is the difference between a lawn that browns in August and one that stays green clear to the fence. Salt air, sun coming off the Sound, long evenings: it is a good place to grow grass if someone is paying attention. It shows in the color.
