In south Texas, while we grow many beautiful plants, we're limited to the plants that don't need lots of chilly time in the winter. Visiting Tennessee is like another world, garden-wise.
On looking up blueberry requirements, I discovered that most of them need as much chill time as many peaches. There are some low-chill types but they still have one other major requirement: really acidic soil. It's the kind of soil found in much of eastern Texas, but not in the region of Texas I live in. 😢 Sad as it makes me, we probably wouldn't be able to keep a blueberry plant alive. Much less happy and fruitful.
