April in Thornton is a wager — a wet, heavy snow one week, and the next week the lawns come up so green so fast you can watch it happen, with Longs Peak still white on the western skyline behind them. Trifecta Lawn Care works in three moves. Mow, so the stripes run true across the yard. Trim, so the fence posts and the mailbox stand in cut grass instead of a shaggy collar. Edge, so the walk gets that hard clean line where the turf stops and the concrete starts. Repeat it week after week from green-up to the last cut of the fall, and a Thornton yard holds its shape all the way through.
