Ok, I've got my Pre M , Post M , my early spring iron fertilization and my final pre m applications decided. What are you guys using for your apps. in the southern states? I'm gonna be doing 2 apps. : 1 in the 2-3 week of april and 1 in the 1-2 week of aug. What kind of break down would you recommend? 18-0-10 or 15-5-10 or 20-10-10 or any other sugestions. I'll be spraying only zoy, cent, st. A, bermuda.

Slim: A soil analysis will tell you that. Generally for our soil; no Phophorus (middle number) will be needed. Something like 15-0-15. Take it to you local county extention agent for analysis.
Your application of maintanence fertilizer should be done a week or so after green-up. Warming up of the soil for 7 days in a row will tell you when to put down your pre-em. Remember that you've got to catch that weed-seed before it germinates and sends out that hair root. Because of that you may be putting down your pre-em earlier. If timing is right and you use a quality pre-em product, your post-em could be just a spotting with the backback unless you've got to blanket for sedges and kylinga. Be careful what you put on that centipede and St. Augustine. Your just north of Charleston. We're in Murrells Inlet.

Thanks RAI

This is what I have so far.

1. Mid Feb. .20% Stonewall 0-0-7
2. Mid-late March 5-10-31 10%Fe + Spot spray 2,4-D
????????Aeration(Depends on customer)????????????
3. Mid April 20-0-10 Slow release + Spot spray ...
4. Mid August 19-0-11 Pre M .86% or + Spot spray ...
15-3-7 Pre M .86% or
16-0-8 all mineral or
20-0-10 slow release or another
5-10-31 10%Fe
5. Mid Oct. 0-0-7 .20% stonewall + Spot spray ...

Ofcourse theres no one size fits all program but this is what i'll be baseing my programs around.

Mainly looking for feedback on application 4. Do I need preemergent that early? Also anyone ever have problems spot spraying with 2, 4-D or simazine?

You don't need to do this--2-4-D will kill centipede and St. Augustine in a heartbeat. There are special mixes with low quanities of Dicamba which is the killer in the 2-4-D. Again--know what you're doing. Fertilizer, in my opinion, is wrong analysis. I'd go with the 20-0-10 (little high in N) in April and forget this. You're going to find out and a late fertilization just before grass goes dormant where it will build up in the root is all you will need until after greenup. That big time shot of N in the early spring will shock your turf.
The other grasses are not something that I take care of a lot.
Again, 2-4-D is generally bad for spot spraying centipede and St. Augustine UNLESS YOU USE THE RIGHT ONE. Southern Ag makes "Weed Killer with Trimec" Check it out as it is blended for centipede and St. Augustine. But still I'd go half rate on them.
PM me if you have any specifics.
