Early May in Chestnut Hill, and at seven the dew is still on everything, the lawns silver and the woods by Hammond Pond just leafing into their first thin green. Chilton Lawn Care starts the cutting season then and keeps it running: weekly mows, edged drives and walkways, trimming around fences and beds, and clearings at both ends of the year. Grass here grows fast in a wet spring and needs a hand to look as though it grew that way on purpose. There is real pleasure in the moment the last pass closes the pattern and a yard reads as one unbroken green surface.
