September is fair season in Gwinnett, the nights finally lose their edge, and the ground is ready to be worked again. New Harvest Lawn Care & Solutions LLC leans into that window around Lawrenceville — core aeration to open compacted red clay, overseeding where fescue has thinned, feeding the turf so it roots deep ahead of the cold. Mowing and trimming continue on schedule while the leaves begin to fall and the beds get cut back and mulched. Autumn labor is the kind that pays out months later. It is a fine thing to see a lawn seeded in October come up thick in March.
