There are probably others that have more expertise than me about containers and cold weather, but my guess is that it would be OK to plant them now if the small green pots they came in are actually the containers they have been growing in and not just some little pot of sawdust or peat that they stuck the bare root plant into to sell. Even then, I'd probably feel more comfortable putting them in a garage or similar when it gets below 30 degrees at night.

Thank you, my garage is not very well lit, should I put a grow light up?

I agree with Scott said. I will add a little. Not knowing for sure what you have makes it a little harder to give advice. I will share part of what I've been told. I have always planted in the ground and not in containers also. So not a lot of experience with containers. I received some blueberry plants one year not much later than this. But they were still dormant and bare root. And they said to plant them and put mulch around them. And they did fine. I would only pot up if I could move the big pot inside at night. I saw some blueberry plants at our local Wally World outside and all leaved out. If yours is like that then I would make sure they were inside when freezing temps hit. You can mulch or insulate to protect the roots too a certain degree but the leaves can get burned bad if it gets too cold on them. Jay

Well I should have been more clear, I am sorry for that. The plants were inside the store planted in smallish green pots in what looks like peat moss. There are small green buds on the ends of the 2' tall stems. They are summit and ozarkblue variety. My garage is a bit dark I have them now by a sunny window in my house. The man in the store said to plant them in 5 gallon containers with half peat moss, and keep the soil acid. Which I plan to do with epsom salt and water. But I am wondering if I should transplant them into the containers now or wait, keeping them where they are. The green pots are about 8" around, 8" deep or so.

Thanks

If you are going to keep them where they are I would probably transplant now. I know many like to wait. If you just have buds and no leaves they are probably just breaking dormancy. I'm sure Scott has more experience than I do. I've only ordered plants from two sources. And know one said it was better to transplant them while still dormant or just breaking dormancy than after they had leafed out and were growing. And that has always been the advice I've followed.

I thought of leaving them where they are until after the last date, due to all the wild changes in weather we are having, them move them outside to a sunny spot after that. I would just keep them in the house, but I fear they would get too big and my window is too small :)
