By noon in July the asphalt along the Golden Isles Parkway shimmers, and the only shade for a mile is whatever a stand of pines happens to throw. Boss Landscaping LLC works straight through it — mowing, edging, cutting hedges back into shape, clearing beds and hauling debris off before the sky opens up to the west. Brunswick grass in high summer grows like it has somewhere to be, so the schedule stays tight and the passes stay straight. There is a moment at the end of a property, blower shut off, when the yard just sits there squared away. That is the part worth the heat.
