Barb from Malden, Mo writes,
What is the best time of year to spray Sahara? Application would be cracks in asphalt.
According to page 3 of the Sahara DG Herbicide product label "For annual weed control Sahara may be applied either preemergence or postemergence to the weeds; however, a late preemergence to early post emergence is the best method of choice in most situations. For perennial weed control Sahara is only effective when applied postemergence and will not control perennial weeds that are not emerged at the time of the application".
