April on Cronomer Hill is mud and meltwater and then, almost overnight, green — the Hudson Valley never eases into spring so much as it arrives all at once. ALL SPRINGS LANDSCAPING meets it with rakes and mowers: cleanups that pull the winter out of the beds, the first cut of the year, edges re-cut where frost heaved them crooked. Through summer it is mowing and trimming on a set week, mulch refreshed, shrubs kept in their shape. Come October the leaves off the big maples along the 17K corridor are gathered and gone before the rain glues them down. A yard tended all the way around the calendar looks different, and anyone driving past can tell.
