Sigel is a small grid of streets with Shelby County farm ground pressed up against every side of it, and in late spring that ground is the loudest green anyone sees all year. Wolke Nursery Landscaping LLC keeps the lawns matched to it — mowing on a regular turn, trimming around trees and posts, edging the walks until the concrete has an outline again. Storms build off to the northwest on summer afternoons and leave the grass running ahead of schedule by morning. A yard mowed, trimmed and blown off carries a settled look that nothing else quite gives it. When the leaves finally come down toward Thanksgiving, the fall cleanup takes the whole place back to bare and orderly.
