Spring reaches East Islip late and then all at once — the oaks at Heckscher State Park hold their bare gray until the last minute, and one warm week later everything south of Montauk Highway is growing fast. Trimarchi Landscaping & Designs meets that surge with mowers and trimmers and a full round of cleanups, hauling off the winter's leaf litter and giving beds and borders their shape back. South Shore ground drains quickly and the turf answers well, which makes for a long cutting season and a lot of Saturdays. What stays with you is the after: a lawn striped even, the trimmer run tight around every post and hydrant, the driveway blown clear so nothing tracks inside. Week by week from thaw to frost, one East Islip yard at a time.
