Noon in midsummer along the Route 12 frontage in Leominster, asphalt shimmering and the strips of lawn between the lots doing their best. LandPro Landscape Inc. keeps those greens honest — mowed on a rhythm, trimmed tight to signposts and light poles, edged wherever the grass tries to creep onto the curb. A property people only glance at from the road still tells them something, and a crisp edge says it plainly. Cleanups follow the year at both ends, spring open and fall close. Leominster, Fitchburg, Lunenburg, Sterling and Westminster are all on the route.
