Evening at Founders Landing in July: the bay flat as a plate, kids still off the dock, and the lawns along the way holding the last warmth of the day. Palencia Landscaping and Tree Service Inc. tends those properties with mowing, edging, string trimming and spring and fall cleanups. Southold in summer asks for consistency more than anything — a week missed in July costs two weeks of catching up. The measure of a good visit is what the place looks like at dusk, when low light finds every edge. Southold, Peconic, Greenport, Cutchogue and East Marion are all on the route.
