Walnut Creek runs down into Lake Eureka at the edge of town, and by late May the whole low ground goes so green it seems to be showing off. Cornerstone Landscaping Services keeps up with that push — the weeks when grass gains an inch overnight and one skipped visit takes two cuttings to forgive. Mowing on schedule, trimming around shed corners and clothesline posts, edging where turf meets concrete so a yard has its boundary back. The spring cleanup comes first, though: raking out the winter mat, opening the beds, hauling off the limbs that came down in the March wind. Around Eureka and the farms toward Goodfield and Congerville, a kept lawn is simply how a place says it is lived in.
