I live in Cary NC( Zone 7 ). I am getting ready to lay empire zoysia sod this weekend. I was wondering if there would be any benefit to applying some organic fertilizer before I lay the sod, and raking it in? I was thinking it may activate the soil a bit. I tilled and leveled the yard this past weekend. If so, any recommendations for a good organic fertilizer? I was thinking perhaps corn meal. I also have a small bag of starter fertilizer that I was planning on spreading a day or so before I lay the sod. Thanks!
