Late July in Manchester, the air over Route 21 goes heavy by two in the afternoon, so the work happens early or it happens late. Caster Oil&Lawn keeps to that clock — mowing while dew is still on the blades, trimming and edging as the light stretches long and gold across the old rail grade. Lawns run wide out here, and the moment the engine cuts and the whole yard settles into one even sheet of green is the point of the whole day. Seasonal cleanups bookend the year, thaw litter in spring and the drop in fall. Manchester, Farmington, Hopewell and the villages nearby.
