Use Of Pre-Emergent and Post-Emergent

Posted by gatorinsc Florida (My Page) on

I live in the central part of Florida and was advised that this is about the time of year to apply a pre-emergent. The problem is that I already have broadleaf weeds that have appeared. Can I use a pre-emergent and a post-emergent at the same time? If not, should I spray Atrazine now and then wait a while to use a granular pre-emergent?

Also, which pre-emergent would you suggest for St. Augustine grass? I received a list of about 8 of them from the local extension office and didn't know if one or two of them work the best?

Thanks in advance for your help!

RE: Use Of Pre-Emergent and Post-Emergent

I have had great success with Scotts Bonus S, which is formulated for southern St, Augustine lawns. It will kill existing weeds. I had a real problem with wild strawberries and Bunus S killed them. As will all weed and feed products, you need to be mindful of root zones of trees and shrubs.
