Elizabeth Avenue runs busy outward from Union Square, and a turn or two off it the city goes suddenly residential — porches, driveways, and lawns fitted in wherever there was room. Green Lawns 4u Landscaping LLC keeps those yards on a set weekly loop of mowing, trimming and edging, with the walks blown clean before the crew leaves. Curbside grass takes a beating from traffic, foot travel and winter salt, so consistency does far more for it than any single big effort. Twice a year the heavier work comes around: cleanups when the ground opens up, and leaves once November settles. The result is a block that looks tended rather than merely mown.
