Ashley from Houston, Tx writes

Can I applied a Weed n Feed following an application of Hi-Yield Atrazine Weed Killer on St. Augustine?

I want to fertilize my St. Augustine after applying Atrazine.

Answer:

You could potentially use BioAdvanced 3 in 1 Weed and Feed For Southern Lawns on your St. Augustine lawn. We suggest waiting at least 1-2 weeks after applying Atrazine since the BioAdvanced product includes a post-emergent as well as pre-emergent herbicides.
 
You can also always purchase a separate fertilizer if you do not need other herbicides at this time. We have more tips and product suggestions in our St. Augustine Care Guide here.
