How do you get rid of invasive bermudagrass in shrub and flower beds?
A. I am assuming you mean that the beds are relatively free of bermuda but get occasional encroachment from the edges. There are several methods that will work but all will require weekly attention during the summer months. The nonchemical method will require hand pulling, trimming and digging the areas infested. The bermuda will invade either on the surface of the bed as runners (stolons) or underground as rhizomes. Water the area you are going to clean up. As the bermuda spreads from the lawn into the beds, it can be pulled back easily in wet soil. Bermuda that appears and won’t pull up easily is probably attached to rhizomes.

After the soil is thoroughly wet, try pulling the it up with the rhizomes attached. If the rhizomes are left in the ground, the bermudagrass will reappear. If it is reappearing in the same area, then spray the clumps with an
