I have an area about 700 -800 sqft that i killed of bermuda grass(w/Round up). A few weeks ago, i power rack this area to get rid of dry roots so i can sod it this fall. And now dead roots are gone, but the bermuda gass start to come back!They are 10 to 15 of them in various spots. Everytime it rains i will see new one come up. It is almost Fall and i want to sod my yard! What will it be the best way for me approch. Should i wait until i get rit of it complately and sod the area next year? If i sod it now will it kill of the new growth bermuda grass?
