North Georgia sits right on the seam where cool-season and warm-season grasses both try to make a go of it, which is why September matters so much here. Turf Masters Lawn Care of Woodstock uses that window for aeration and overseeding, opening up compacted clay and giving new seed a real chance before the nights cool off. The rest of the year runs on mowing, edging, trimming and cleanups that keep the stand thick and the weeds outnumbered. Turf built up in the fall is what carries a lawn through the following August. Few things in this trade beat walking a yard in October and seeing new grass come in even.
