Hi Barry, I know exactly what you're talking about, it has been bloody cold around here recently, with the ground not being able to thaw before the next freeze, and often the frost not even to melt, but the best idea would be to leave them in the mini greenhouse, which if its one of the ones I'm thinking off will be unheated and hold out the worst but still be enough to chill them through to keep them asleep, all my deciduous trees, Hawthorns, Acers, the lot are in my unheated greenhouse with both vents open, they still freeze, but they're protected from the winter winds.

I would, in your situation, put the trees on the floor or the greenhouse(providing its not concrete, if it is pad it out a little with fleece or old bedsheets), open the vent(s), or unzip the door, but leave it hanging so it still blocks out some of it. Just keep an eye on moisture levels, and if its gona get really cold like the reported -14c I've heard on the radio in some parts of the country, zip it up, or close the vents for the night.

-Good Luck-

-Matt-
