Union Hill in late March belongs to neither season — grit on the shoulders, old snow gone gray in the ditch, and the first green showing wherever the sun reaches. Superior Lawn Maintenance LLC works both sides of that line. Warm-weather work means mowing, trimming, edging and the cleanups that bracket the growing season; cold-weather work means plowing, opening walkways and salting. The changeover can happen in a week, sometimes overnight, and the trucks are ready either way. What stays constant is a property that never looks like it was left to fend for itself.
