What is the easiest way to kill bermuda grass in existing flower beds? I don't want to disturb my plants.

The only way know to kill bermuda is to pull it out. No matter how many times you cut it, it keeps coming back. It seems the more I cut my bermuda grass, the more thicker it grows and kills out more weeds.

Yeah, what he said No tilling, it will just drive the roots/runners deeper and compound your problem.

After removal, a good physical barrier which goes below and above the surface and don't spare the string trimming. Bermuda is an extremely aggressive weed er... grass.

I've had great luck with a layer of old newspaper in flower beds. Two years ago, I had two large beds that were absolutely overgrown. I pulled a lot of the grass and cut the rest back to ground level. Then I put down about five layers of old newspaper covering all the ground between plants and covered it with a good layer of cedar mulch. I repeated the process last year, and this year I have hardly any grass in either bed. The plants were not negatively impacted at all -- as a matter of fact, they seem to like not having to compete with the grass anymore! This year I plan to just lay the paper at the edges of the beds, where I might get some "creep over" from the lawn.

One thing that has helped but gotten rid of the bermuda grass is digging a 4-5 inch trench in front of your flower beds. I did this last fall and when i see the bermuda grass coming in, i can pull it up right away with no problem. Robbie
