I know the majority of the OB promotes weed then feed so what do I use for this lawn grass mixture?

That's a tough one... Bermuda and Centipede require vastly different solutions, although of the same chemicals, to selectively combat weeds. Just about have to choose one over the other.

I have the same thing and I'm gonna try the Scott's turf builder weed n feed in the yellow bag. Says it's safe for Bermuda and centipede.

Nothing. I was just saying if you are doing liquid herbicide applications, the formulations are different for Bermuda versus other grasses.

It's "Southern weed and feed" by Scotts. It's got a picture of St Augustine on the front. I'm an idiot.

What should I do for my 90 percent Bermuda yard?

I think you talking about the bonus S in the purple bag. Get the turf builder in the yellow bag and you should be good. Just read on the back what grass is safe. I plan on using it this Saturday if the weather stays right.

If was the purple bag then you might have a big problem. My neighbor used the bonus s southern and it killed all of his Bermuda.

Try celcius wg by Bayer. It's about 100 per bottle but makes around 60 gallons. It kills everything but the grass.

The biggest problem with having both centipede and bermuda together is fertility. Bermuda needs higher rates of fertilizer, but centipede is very sensitive to over-fertilization. Too much nitrogen can cause decline.

As far as herbicides go for the most part, if it's safe on centipede it's generally safe for bermuda but not the other way around. Bermuda is tough as hell and can usually recover from just about anything.

I wouldn't hate that. I bought the house almost two years ago and I've never been crazy about the grass.

How long did it take to die? Did St. Augustine take over?
