May at the Southold town beach: rosa rugosa blooming along the fence line, salt on everything, and the lawns finally thick enough to need weekly attention. Salty Roots takes them on with mowing, edging, string trimming and seasonal cleanups. Growing grass this close to open water is a negotiation — wind, sand and spray all get a vote — and the answer is simply showing up on schedule. Come back to a yard you cut last week and you can read your own work in it, which is most of the reward. The route covers Southold with Peconic, Cutchogue, Greenport and New Suffolk.
