In the next 2 weeks, im going to re sod my back yard. Im going to spray with round up to kill the grass that is there now and then rake it up once its dead. After this is done, im a lost puppy. I have seen some that say to roto till the yard and some who say don't roto till and aerate instead because the ground will be mushy for a long time. Im live in South Carolina, Charleston area to be exact and am going to put down Palisades Zoysia. My backyard only gets a few hours of sun every day. What soil supplements do I need to put down? Here is what the yard looks like now.
