I am trying to grow centipede grass in Columbia South Carolina. My yard is nothing but weeds. I seeded last year and it started to take, but this year it all died. A soil test was recommend by a friend and here are the results. It looks like the Phosphorus is 10 times what it should be. Can I add new soil to the yard, or do I have to dig it up and replace. There are spots in my yard where even weeds wont grow. Thanks!
