Hi LL. Mine will be moved into a cold greenhouse lined with bubble wrap. I will sink the pot to its neck in the compost filled bed. I do have a heater I can put on at night if I think it's going down below -10C and I can also cover it with a couple of layers of horticultural fleece for added protection.
Next spring I will start wtareing gently when the temps get around 5 to 8C which is when I expect it to start thinking about growing again and then I shall take it out again after the worst frosts and pot it into a bigger pot for it to grow on and get bigger.
Mine will be planted out when it reaches a pot size I can no longer carry with OH so 60cms max or 90cms if I use one of my plastic terracotta effect pots which are so much lighter. I keep mine on the terrace in summer and it gets full sun most of the day but has a saucer of water to keep it moist. When it does get planted out it will be at the edge of my unlined pond where it can get its roots deep into moist soil. It will be in full sun but they can take partial shade too.
