Landshark: If you're spraying PM me for a mix. Centipede is not a real green turf but apple green. Iron incorporated with micros as Greendoctor will do wonders for the turf especially on this sand, hardly no soil except what is appended. For what it is worth: 8 out of 10 males are color blind to some extent. If color of turf is bothering anyone, get a second opinion from your wife or close friend.
