By August the corn stands taller than the truck and thunderheads build in the west most afternoons, so the trick is finishing the route before the sky opens. Heartland Landscaping Inc mows, trims and edges through Effingham's long humid summers, then comes back in fall to clear the leaves and put lawns down for the cold. Grass in this black-soil country grows with real appetite when the rain lands right. Cut too short in that heat and it burns; cut steady and it holds green into September. Knowing the difference is most of what the work is.
