My lawn is mixed in the back yard and I live in North Texas. I want to get rid off my St. Aug in the bermuda as well as the crabgrass and nutweed. What can I apply over the whole lawn to kill these without affecting my bermuda. As of today the lawn is just staring to come out of dormancy.

Here are my suggestions:- apply 2-4 D to kill weeds and it will harm the St. Augustine.- nutsedge, try a product called Image (available at ACE or Home Depot).- if Image fails, buy some Manage weed killer (about $12 for a package to make 1 gallon of spray so you will have to spot spray… but it works)- For crabgrass, put a pre emergent down then get some roundup and spot spray the crabgrass. Place a piece of 4-6″ dia PVC pipe over the crabgrass and spray to keep from killing your entire yard.Good luck.
