The application timing for Trimec Southern Herbicide can vary from region to region. You do want to make sure that the weeds you are treating are actively growing at the time of application, and apply when temperatures are between 65-85 degrees. It is best to apply when the weeds are first growing, rather than when they are well-established. You may want to contact your county cooperative extension office to find out the best time to apply for the specific weeds you are treating in your area.
