Sounds like you need lots of acidic mulch such as pine needles, etc. as well as acidic fertilizer

Yeap, they love acidic soils.

The recomended varieties for the lower south are brightwell,premier,climax,tiffblue,powderblue and alapaha

I recently planted a SharpBlue southern highbush. I live on the Texas coast. It's supposed to require 200 chill hours and is one of only two blueberry plants I could find with such a low chill hour requirement. (The other is Sunshine Blue.) Won't know until next year whether it produces berries.

Buchanan's in the Heights has a lot of blueberries that are bred for our area. They are sold every year at all of the Master Gardener fruit tree sales, too. And there are other nurseries that carry them, they aren't too hard to find, but you do have to read the labels. I don't grow them and don't know the varieties, but there are a lot to choose from now.

Rob, I've always been interested in growing blueberries. I'm near Houston, too. I have nearly 100% sun though there is some amount of shade under or near my trees. I am willing to amend my soil however much works really. I often make my own mulch even...
