There is a week in May when Preakness cannot decide on a single green: the new maple leaves are one color, the rhododendrons up at Laurelwood another, and a freshly cut lawn a third. Green Dreams Landscaping spends that week and the twenty after it mowing on a rhythm the grass can count on. Beds are edged into a real crescent, mulch goes down even, and string trimming finishes the corners no mower deck will ever reach. By July the schedule matters more than anything, since a lawn cut on time through the valley's humid stretch stays dense instead of going ragged. Come autumn the leaves come off in passes, and the yard goes into the cold looking deliberate.
