Hello I am in zone 7a.

1) I have my Caroline raspberries in approximately 3-5 gallon pots. When I take them into the garage for the winter I would like to cut all the branches down to 1-2 feet from 3-5 feet. Will doing this ruin next years fruiting on this years canes or does it not matter as long as I don't cut them below dirt level?

2) I also have a couple of potted pomegranate trees that I want to plant next spring. Can I bring them into the garage just like the the raspberries or do they need special treatment?

3) Potted blueberries and Figs I assume they can go in the garage the same way as the raspberries?
