re: too late to fertilize grass?

Actually, not having a true fall is a big reason not to fertilize late in the year. Our turf grass does not have time to slowly go dormant like other climates....it basically grows until frost. If you promote fresh new growth with nitrogen fertilizer, that can be killed with a good frost or early freeze.

I don't think its a big deal either way, but applying fertilizer after the end of August is not recommended. LSU AgCenter knows a lot more about plants, grass, etc. than a few folks on a message board. Their recommendations are based off of experience and research here in Louisiana.
