By mid-October the color in Freehold drops out of the trees and settles into the grass, which turns deep and slow and holds it right through the first frosts. Huntergreen Landscaping likes this stretch of the year best — cool air, soft ground, mowing that finally lasts more than a week. The route becomes mowing plus cleanups, clearing leaves off the turf before they mat down and smother it, tightening the edges one more time before the season closes. A lawn put to bed properly in Monmouth County wakes up green weeks earlier in spring. There is real pride in that: work done in October that nobody notices until April.
