I realize that at about 85 degrees weeds start to shut down and won't absorb much weed control product, but I was wondering if any of you guys had any tricks to help weed control work better in the heat. It is frustrating to know that after 1 o'clock or so none of my weed control is really working as it should be. I need to go back often and do follow-up sessions early in the morning. I am currently using Speedzone. Thank you for all of you expert opinions. I've had great experiences with this site and all the help I receive.
