By the second week of April the pollen has come down over everything in Johns Creek — cars, mailboxes, the surface of the pond at Newtown Park — and then one good rain washes it away and the grass takes off like it has somewhere to be. That is the season Weed Pro Lawn Care is built around: weekly mowing through a Georgia summer, when an afternoon thunderstorm can put three days of growth into a yard overnight. Strings trimmed tight along fence lines and the low banks off Cauley Creek Road, hard edges cut in along the drive, clippings blown clear of the walk before the truck pulls away. The heat is real from June into September, so the day starts early and follows the shade around the house. And in the long evening light out toward Shakerag, a lawn mowed that morning is still holding its stripes.
