Last thing I want to do is to green up the crab grass I'm trying to kill.
We typically recommend waiting atleast 24 hours up to 7 days in between applying herbicides and fertilizers to avoid overstressing the turfgrass unless previous applications have shown tolerance to using a fertilizer and herbicide together. The Drive XLR8 Herbicide Crabgrass Killer does advise that a liquid nitrogen fertilizer can cause some yellowing therefore a small test application would be recommended if deciding to tank mix. Please review the product label for tank mixing instructions prior to mixing in your sprayer.
