Answer: The only product I am aware of is Agralawn Crabgrass Killer. Made from cinnamon bark, it is an all-natural weed control used as a spot-treatment to kill crabgrass, basket grass, chickweed, clover, and other similar weeds. Safe for use around people, pets and the environment. 2 lb. container covers 100-200 sq. ft. As far as I know it is only available online from Planet Natural.
There may be similar products in your local garden center so check around. Best wishes with your lawn.
