Blue Heron Park keeps its ponds tucked behind the oaks, and the streets around Annadale and Eltingville borrow that quiet. Asap Landscape & Design works both ends of the calendar there — mowing, edging, trimming, mulch, planting and design work, cleanups when the weather is willing; plowing, shoveling and salting driveways and walkways when it is not. Designing a yard and then maintaining it means watching an idea take root across a few summers, a rarer pleasure than it sounds. In winter the same yard becomes a question of clearance and traction, and it gets the same attention. Same ground, different problem.
