Rockland grew up around shoe shops and brick blocks, and the old rail bed still draws a straight green line through town. DiTullio Landscaping LLC. works both halves of the calendar along those streets — mowing, trimming, edging and cleanups while the ground is working, then plowing driveways, clearing walks and salting steps once it locks up. A town built close needs its snow put in the right pile and its grass cut to the right line; there is little room for either to be wrong. The satisfaction is identical in July and January — a property that has plainly been handled. Two seasons, one habit.
