India Brook keeps time for this corner of Morris County — high and loud with April melt, low and clear by August, iced at the stepping stones in February. DWS Landscaping, LLC keeps the same calendar. The green months mean mowing, edging, string-trimming the fence lines and mulching beds until a hillside lawn looks combed. The cold months mean plowing, shoveling and salting those same properties, so nobody has to change phone numbers in November. Cleanups bookend the whole thing: the wet mat of leaves in autumn, the winter's grit and twigs in spring.
