May turns the corner of Jericho Turnpike and Route 111 into a green tunnel almost overnight, and the yards behind it grow just as fast. Gappsi, Inc. runs its lawn work on that spring surge — cutting on a tight schedule so no property ever looks unattended, trimming close where mowers cannot reach, edging the walks back to a clean line. Cleanups open and close the season, clearing winter's leftovers in April and the leaf fall come November. Every job ends the same way, with the hard surfaces blown clear so the finished lawn is the only thing you notice. Smithtown, the Village of the Branch and the surrounding towns are all within the route.
