|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. You may have to start all over, removing both turfs and planting the one you like best.
