Every autumn the hawks come down the Hudson past Lenoir Preserve, and if you happen to be working a lawn on that side of the city you look up more than you should. Superior Yonkers Landscaping Professionals keeps the work moving all the same — mowing, edging, string trimming, mulching, hedges kept clean-lined right through the season. Fall is the long chapter here: leaves off the turf, beds cut back, the grass sent into winter short and clear. Spring answers with its own cleanup, the seeding, the first cut that makes a whole street look alive again. The lawn is a small thing, and doing it right is not.
