From what I can gather from some of the posts, once you lay sod, St.Augustine in my case, it is almost impossible to get phosphorus down to the roots to lower the PH level of the soil. I understand that I need to put sulphur on it too. Is there a site where it will tell me what and how much to put down for sodded grass? I found tidbits on it here and there, but nothing that shows what combination I can put down together. Can I put superphosphate and sulphur together for example? Will this burn the grass?
