By mid-July the heat settles onto the west side bungalow blocks and the green pushes back hard — grass shooting up between cuts, hedges leaning out over the walk, everything reaching. Green Guys Lawn Care & Maintenance, L.L.C keeps that energy in bounds with regular mowing, edging, trimming and cleanup, week after week through the long middle of the summer. There is real color in a Detroit lawn in July, deep against red brick and a white porch rail, and it only reads that way if somebody keeps it even. The mower stripes run one direction this week and the other direction the next, so the turf never picks up a bad habit. A small thing, and the whole block notices.
