My lawn is mainly St. Augustine grass. I recently noticed some invasion of Bermuda grass any recommendations on killing the Bermuda without damaging the St. Augustine?

This is a tough process. You might try putting out atrazine based weed and feed. Atrazine hurts and sometimes kills bermuda.

Also mow the grass high to encourage St Augustine.

Good luck.

In my experience, atrazine slows down the St. Augustinegrass and allows the bermudagrass to come back stronger.

Atrazine will kill St.Augustine if you put on too much. Been there did that.

You could spend the big money and buy some Prograss from you friendly Lesco salesman. That’s what I did. It takes 3 applications, but it only controls, does not eliminate the bermuda grass. So far, I’ve put down one application. I mixed it with atrazine.

The bulk of experience in Texas is that St Augustine in full sun will easily choke out bermuda, nutgrass, and every other grassy weed with deep watering and mowing high.
