Cranbrook Road runs under a canopy so deep that September light reaches the lawns in coins and slivers. Modern Tree & Landscape llc keeps those shaded yards mowed, trimmed and edged, where grass grows thin and slow and every pass asks for a gentler hand than it would in full sun. Cleanups lift the litter of the canopy off the turf so whatever light there is can actually get through. It is a quieter kind of lawn than the open lots on the east side of town, and it wants different treatment. Birmingham's trees are the reason people fall for these streets — the lawns just have to live underneath them.
