I laid the tarp down over the infected area in order to bake the Bermuda to a crisp. Let's hope this works!
Hopefully the heat and lack of light will weaken the Bermuda and even kill it off. If any root remains alive I know it could easily come back so after I remove the tarp I'll double dig the area and try to take out any roots I find.
What strategy have you used effectively against Bermuda grass?
