Many Columbia mornings open with fog pooled in the American Bottom below the bluffs, a soft white sea that burns away as the sun clears the fields to the east. AQ Lawn & Tree LLC works the yards up on the high ground, where grass grows thick and wants cutting week after week once spring takes hold. Each lawn is mowed level, then trimmed along walks and drives until the lines sit clean against the concrete. By the time the last of the mist lifts off the floodplain, a freshly finished yard is catching the full light of day. Lawn care here keeps pace with a bluff-top town that greens up fast and stays that way.
