The best hour in a Marietta summer is the one just after sunrise, before the humidity settles in and while the streets toward Smyrna and the Silver Comet corridor are still quiet. Clean Air Lawn Care starts there, working through mowing, edging and trimming while the dew is still on and the cut is clean. Yards here run to Bermuda in the sun and fescue in the shade, each wanting a different height and a different week, and the mowing is set accordingly. Beds get weeded and mulched, hedges get taken back to a shape, and autumn's leaf load gets moved off before it smothers what is underneath. By the time most of the neighborhood is on its second cup of coffee, the lawn is done and the walk is swept.
