By the middle of June a Long Island lawn grows faster than anyone can keep up with alone. Around the old barns and gardens at the Islip Grange the grass goes ankle-deep in a week, and every yard on the surrounding streets does exactly the same. C & A Landscaping keeps that pace for its customers — a weekly cut, clean edges along the walks, trimming where the mower cannot reach, and cleanups at either end of the year when the pin oaks let go. The reward is plain and visible from the sidewalk: an even lawn, sharp at every border, cut before the weekend rather than after it.
