East of the village the ground lifts into low sand ridges left behind by an ancient lake, and oaks stand where that water once ended. Timber Crest Landscaping keeps South Holland lawns in trim under those trees and out on the open blocks: mowing on a set rotation, trimming close around posts and fences, edging the concrete so the turf stops in a line. October is the long stretch here, with leaves down off the oaks and everything raked away before the ground stiffens. Spring then finds the yards ready instead of buried. The reward is simple enough, a lawn that looks tended from the street on any ordinary Tuesday.
