Along 23rd Street the sidewalks run for miles, and every one of them meets a lawn that either has an edge or does not. OCD Lawn and Tree LLC comes down firmly on the side of the edge — the line cut true, the turf held back off the concrete, the walk left spotless before the truck moves on. The cut and the trim work are done at the same pitch of attention, and trees and shrubs get shaped so nothing crowds a window or a walkway. In fall the leaves are cleared down to the last drift piled against the fence. Detail is not fussiness; it is the difference between mowed and finished.
