    I had covered my blueberry pots with bubble wrap as I was warned that blueberries wouldn't survive the winter.

    Essentially, my father-in-law told me that they can't survive the cold, which didn't seem right to me as all the info I had read online seemed to suggest they were okay with the cold. Since I couldn't get any specific temperatures that might be considered too cold for them, I decided to be careful, just in case.

    Sinking the pots in the soil wasn't an option, so I decided to insulate the pots. The web articles I read suggested jute sacks or bubble wrap.

    Bubble wrap was easier. Husband's office had metres of that stuff being thrown out.

    So, sheets of bubble wrap around the pots... even the little 9cm one. And fleece during the worst of the snow brought in by the Beast from the East, but mostly they were all exposed. They were outside the whole time, right next to the west-facing wall of our house.

    They managed just fine.

    Pot size could be an issue - I had some in 35ltr bags, and some in regular 2ltr pots - I probably would have brought the little ones into the polytunnel if I'd had time before the storm hit, but they survived fine anyway, my plot is fairly sheltered. 9cm pots might not fare so well in a cold snap?
    He-Pep!

    I wasn't really expecting the blueberry plant in the small pot to survive. It was one of those plants I wasn't quite invested in. I wrapped it up because I had bubble wrap to spare, and was pleasantly surprised to see it made it through.

    Thank you for advice, Runtpuppy. This winter will have raspberry and strawberry in pots to produce early fruit (which they did well this year). One of the blueberry in a pot died, think vine weevil, so they are now in a bed.

    Just a quick update on the Blueberries in the tunnel, all are full of blossom so hopefully I'll have a good crop which the birds won't get at, I have removed the plastic from the door and replaced with wire mesh so there's ventilation and as the tunnel is a Keder I have an opening at the other end which helps as well, I've been watering the plants once a week, does anyone have a Keder tunnel, I've had mine 15 years and it's still in great shape, it came with a 10 year guarantee and the company emailed me after 10 years to see if I was still happy with the tunnel

    Thanks for the update - always interesting to know how things are progressing.

    I bought some blueberries on offer last year and kept them in containers outside over winter - been mild here so hard to tell if that was a good idea or not. Anyway I moved them in to the poly-tunnel a few weeks ago to pot on and have left them inside for now, as I don't need the space yet as I plan on putting tomatoes there later. One is flowering now and the others have buds on, so fingers-crossed :-)
