Late August, and the milkweed along the field edges south of Oswego fills up with monarchs stacking for a trip none of them has made before. Monarch Mowing LLC works those same weeks, keeping lawns cut while the grass makes its last hard push before autumn. Mowing on a steady cycle, trimming around trees and posts, edging where sod has crawled onto the sidewalk — all of it in one visit, start to finish. Clippings come off the drive and the walk before the trailer gate goes back up. A lawn kept on schedule through the tail of summer heads into fall without a scar.
