A marker in Rutland notes the geographic center of Massachusetts, which makes every road out of town a road downhill. Green Gardens Landscaping & Nursery works the lawns around that center — cutting at a height the summer sun cannot scorch, trimming around foundations and posts, edging so a bed keeps a clean lip all season. The year opens with a thorough spring cleanup and finishes with an autumn one, and in between the visits are unhurried and done the same way each time. A yard that looks composed does not happen by accident. It happens on a Tuesday, every Tuesday.
