Fog collects in the Greenbelt hollows on June mornings and burns off slowly, leaving the lawns up on Lighthouse Hill wet and gleaming until nearly ten. It's woodland ground here — shade in patches, roots close to the surface, grass that grows in moods rather than evenly. Prime Sprinkler handles that unevenness with regular mowing, edging where lawn meets the winding drives, trimming the wild margins back, and clearing beds so the plantings hold their shape against the tree line. A kept lawn beside deep woods is a conversation between two ideas of green. Getting the border between them right is the whole art of it.
