Reading holds a canopy of maples over its side streets, and for about three weeks in October the lawns beneath them are more leaf than grass. Radocckia Tree Care LLC keeps those yards in order — mowing, trimming, edging, mulch, and the raking and hauling that turns a buried lawn back into a lawn. Grass under old trees wants a lighter hand and a closer eye on what the shade is doing to it. Properties across Reading, North Reading, Wilmington, Lynnfield and Wakefield fill the schedule. The last cleanup of the year, done right, is a small gift to next April.
