The Q&A Archives: Bermudagrass in St. Augustine

Question: I just laid down a sodded St. Augustine lawn and have quite a bit of Bermudagrass growing among the St. Augustine. Will St. Augustine choke out the Bermuda or vice versa? Is there a way to get rid of the Bermudagrass without harming the St. Augustine grass?

Answer: I have observed that the two turf types often co-exist for a long time rather than one eliminating the other.

Here are some points to consider regarding what conditions may favor one species or the other:

In the shade, St. Augustine has the edge.
In drought conditions, Bermuda has the edge.
Infrequent mowing schedules may favor St. Augustine a bit.
Taller mowing heights may favor St. Augustine.
Bermuda is more tolerant of heavy foot traffic.

I don't know of any herbicide that will kill Bermuda but not harm St. Augustine.
