fruit bushes overwintering advice please??

[Liz 89]

i have a cranberry, blackcurrant,redcurrant, whitecurrant and blueberry bushes, and at the moment they are all in an unheated greenhouse. i want to take them out over winter to make room in the greenhouse and i'm pretty sure all of them are ok (correct me if i'm wrong) except the blueberry. are blueberry bushes ok outside to overwinter? the reason i'm unsure is because the stems look more delicate on the blueberry bush than on any of the others. thanks for any help. xxxx

I have blueberry bushes in a boggy area and also some whitecurrants. They have been winter hardy since they went in a couple of years ago, although winters are quite mild in my area. They go dormant for the winter anyway, so cold damage is much less likely.
I'd expect yours to be winter hardy too.

My blueberry bushes were all fine outside over winter.

I have yet to keep a cranberry alive though and I know others have had the same problem, so that might be the one you want to do more research on!

My cranberry died last winter in a pot, was thinking of protecting my new one in the greenhouse this year but haven't decided yet.

None of these plants need to be in a greenhouse. They would be far better off in the open. In pots if you have no open ground, but certainly the blackcurrant, redcurrant and whitecurrant would be far happier in the open. They make very large bushes if planted in open ground, so you get far more fruit. As for cranberry and blueberry I haven't ever grown them so can't help.

They are all very hardy. Where cranberries and blueberries come from there is much harsher - well I should say there is actually severe - winter.

Hardy plants struggling like that in winter here is usually due to excess waterlogging and root rot and not the cold, won't have that problem with blueberries either, bog plants, as FB says. I think both cranberry and blueberry want an acidic soil/bog though. Good luck.
