I have a good customer that wants me to spray for all their weeds, then go in and overseed their yard this fall. The yard mainly has crabgrass and clover so I was planning on hitting it with Q4 - I'll have to look at the label for the time period on seeding after though. Note: I do not treat their lawn, nor do they have it treated during the year, so yes it is full of CG, however they do have a decent stand of fescue. My question: Does it make sense to spray now that its getting closer to fall considering the CG will be dying out? Or should I convince them to not worry about spraying. If you did recommend spraying, when would be best considering the scenario? Thanks.
