I have seven blueberries that I'm trying to decide how to pot. They are 3-4 years old, in 1-gallon pots. I have 22" decorative pots that I would like for them to have as a permanent home, but for this year, I think they would swallow up these little guys. I am considering putting them in 5-gallon pots for the first year or two, then transplanting to the bigger 22" pots.

If I do this, should I use the black nursery pots from Greenhouse Megastore? Or are they too thin? These will be sitting on my second story deck, and I'm afraid those nursery-style pots are too flimsy and will cook the roots. I see many of you talking about your 5-gallon or 15-gallon pots...are you talking about these thin black pots?

Where do you get your pots for the type of use I'm describing? Thank you.
