Hello, this is my first post Before everything, thanks for sharing so much useful information. The temperature zone where I live (Romania, Brasov, Southern Carpathians mountain region) is 6, based on this map http://www.uk.gardenweb.com/forums/zones/hze7.html Currently I have 3 Wollemi Pines, one still potted, the others planted out this year in the garden. I hope they will survive temperatures that definitely can go well bellow 12 Celsius. I intend to document their winter survival by taking pictures of them and a thermometer showing the exact temperature at that moment on the most freezing days and hopefully of their new growth next spring. I have reason to believe they will survive as the Wollemi Pine shown in the first picture was already planted out in February last winter during a warmer period (until then it had been kept potted outside by the house wall, in a sheltered position). Afterwards, there was again a period of freezing and snow (unfortunately I have no picture of that), very encouraging for me as I know it had already survived freezing temperatures. The second one was planted out in July, and now for the second time shows new lateral growth this summer, which I am afraid will not have the time to harden off.
I agree. And I am prepared for the worst outcome. I intend not to give them any extra protection other than against full sunlight. But at least I will know for sure what are the chances for a wollemi pine in this zone. And though I don't like keeping any tree potted indefinitely, I will have to do so with my third wollemi pine.
Surely you are wasting your time and the plants as you have much too cold a climate for this species.
