The reason for applying CGM in the fall is to stop the spring wildflower weeds from sprouting. If you have a dense turf, you don't need CGM. If you have a thin turf, then the answer will depend on where you live and when the spring wildflower seeds sprout in your neighborhood. For the spring application we look to nature for the answer. It seems that the summer annual weed seeds sprout about the time the forsythia flowers are in full bloom. We have not identified a similar "natural" timing device for fall, but if anyone knows of one, or could suggest one, we'd all appreciate it.
