I saw a thread on this earlier this year but I couldn't find it. I need a good fertilizer/pre-emergent program for a very large area (5+ acres) covered in common bermuda. I'm on the edge of zone 7a / 7b (I think). I'm more used to fescue, but here's what I'm thinking... May - starter 18-24-12 June - 24-5-11 with 5% iron July - 18-0-18 August - 18-0-18 ? September - 5-10-31 ? What would you use? and where would you incorporate the pre-emergents. Thanks!
