I sprayed for Creeping Charlie about 3 weeks ago. I used a product called "Drive" which was highly recommended. I also sprayed another yard for Dandelions with weed b gone max. There hasn't been a thing die. I can't find out anything about the fall habit of plants sprayed in the fall. I was wondering if the chemical is working on the roots and will keep the plant from growing in the spring. Anyone have the answer to this?
