Scott's Sountern Bonus S or Ace 15-0-15 centipede? (Clemson: buy, university)

[lenniel]

Going to fertilize the yard tonight. 100% centipede on clay, about 3 years old.
Ace on 17 by 526 is selling a 15-0-15, not sure if that's just fertilize or weed/feed, or can do the Scott's Bonus S Southern weed/feed.

I know Scott's had a bad batch last year but I'm sure that's been corrected.

Anyone have an opinion on which to use (or a different option?)

I'd go with Ace or better yet Possum's. Scott's doesn't make a fertilizer with 15 nitrogen content.
I find that something that claims to do 2 things at once (such as weeding while feeding) usually doesn't do either well.

At this stage of the game, you're about a month late with the Weed Killer part. Ideally they should be two separate applications. The timing is the critical element here. Use Clemson's Horticultural website for guidance.

As for the "Feed" part -- that's just basic Nitrogen, the first number in the 15-0-15. Buy whatever is cheapest. You'll need another light application in August, and this stuff doesn't really store too well. Just buy enough to get you thru the summer.
