September is the forgiving month in Preakness Valley, with cool nights, the humidity gone, and grass thickening again after the August grind. Yianni's Landscape Group cuts into that stretch with mower stripes laid straight enough to sight down, the way the open lawns at Preakness Valley Park run toward the tree line. Edging along drives and walks gives the whole property a drawn outline, and trimming clears the fences and foundations a deck can never manage. Then the leaves start, and the fall cleanup carries the season out in a few thorough passes. By the time the ground hardens, the yard has been brought cleanly from one end of the year to the other.
