In New City the old Dutch Garden keeps its brick paths and low stone walls in careful order, and that same instinct — lines held, edges kept — is what Bob Destaso Landscaping brings to a lawn. October is the proving month around here, when the maples let go all at once and a yard can disappear over a single weekend. Mowing, clearing, the last cut taken low before the ground hardens: unshowy work that shows up immediately. A property that looks looked-after changes the whole street it stands on. Lawn care across New City and the rest of Clarkstown.
