In June the big cottonwoods along Frenchtown's drainage ditches let go all at once, and their seed drifts across the yards like a slow, warm snow. Family Roots Lawn Care works those backyards — around swing sets, the worn path a dog has made along the fence, the thin shade circle under a silver maple. Mowing, trimming, edging and cleanup are the tools, but the aim is a yard people will actually use on a Saturday. Nothing elaborate is needed for that: grass cut even, lines held, nothing left behind in the drive. A lawn that invites you out onto it is doing exactly its job.
