I am located in southern Indiana and have tall fescue for a lawn. I
had my soil tested this spring and it showed that my soil was extremely
lacking phosphorus and potassium. This spring I put down some 6-24-24.
But from what I have read for fall fertilizer, you want a higher
nitrogen content. So, what should I put down now? My initial thought
was to put down some 13-13-13, but then I saw some 18-24-12 at HD, but
it cost about double what the 13-13-13 was. I understand the numbers
and how to calculate lbs per bag, so I was thinking to just put down
about 1.5 times as much 13-13-13 to get me about equal to the 18-24-12.
Or should I stick with my soil sample and put down 6-24-24?
