I have a number of blueberries in pots in my backyard, and have had blueberries in pots for years. Right now I'm putting some new Azalea soil in the pots and working it into the top inch or so of soil.
The plants I started out with are not the ones I have now, but here's the current line-up:
- Duke
- Jubilee
- Darrow
- Sharpblue
- Misty
In the past I've had, Blueray, Bluecrop, and Earliblue.
The trick with blueberries in pots is to keep them super happy. Give them a Azalea Mix Soil, and top it off with some redwood bark to keep the soil moist when it's warm out... Keep them pruned (take out any dead branches, and any that are growing toward the center of the bush, and any that are crossing each other), and well watered when it's hot out (containers soil dries out faster).
