In February a bermuda lawn in Forsyth County is straw-colored and looks like nothing whatsoever is happening, which is exactly when the year gets decided. Kemko Lawn Service works that calendar, putting pre-emergent down before the crabgrass gets its chance, then feeding, treating broadleaf weeds and aerating in their turns. Timing beats effort in turf: a week early is fine, three weeks late is a whole summer of chasing. By May the dormancy has flipped to solid green and the weeds simply never showed. That quiet absence is the entire point of the program.
