I have approximately 18000 square feet of centipede grass in my yard here in western north carolina. I used an application of Milorganite on my yard once in the spring and once in the fall. I have had great results. The centipede grass was put down as a sod one year ago. It is now very thick and lush just by the two applications I have used so far. Milorganite has been very effective in getting my centipede sod established and looking great.
