If the roots are exposed to a hard freeze and dried out, they will die. This is caused by tilling. Bermuda can be turned brown by roundup but it often comes back.
Yup. Problem is NOTHING else will come back ... but that damned bermuda grass will!
I have a plan ... (Yes, I heard that collective defeated sigh men let out when a woman says "I have a plan" ... ). I'll let him till once. Just so he can get it out of his system. Good thing for him I didn't feel good last year and didn't get everything done the way I wanted it or there would be nothing to till ... Just wait until I show him what he needs to till up in the front yard ...
