14 days after the 1st application to spots I missed plus to spots I did not miss that don't seem to be responding? Or should I wait the full 3 weeks. After 3 weeks is a 2nd application recommended?
You could potentially reapply Drive XLR8 Herbicide Crabgrass Killer at a 14-day interval as long as you are treating established turfgrass and the turf is not otherwise stressed. Typically, you will need at least 14 days to start seeing the full results of an application of this product. Be sure that you are using a methylated seed oil surfactant such as Duo Stick for best results.
If you would like to share more about what weed(s) you are targeting, then we can assist you with more specific information.
