Late March along the timber at Humiston Woods is all mud and birdsong, and the lawns in town wake up about a week behind it. Chief Tree Services & Landscape LLC meets that turn with the first mow of the year and then keeps to it, cutting, trimming, edging and clearing winter's litter off the turf. Through summer the work is rhythm; by November it is the cleanup that puts a yard to bed. Then the plows go on, and the job becomes driveways opened, walks cut clean, and salt down while the sky is still grey. Pontiac gets both halves of its year handled by the same set of hands.
