Unwrapped!

That's it, I've decided it's not going to freeze any more. The treeferns have been unwrapped for the warm season! They seem to have done fine over the winter as far as I can tell... a bit dry on the trunks and a bit damp on the inside which is decidedly the Wrong Way Round. Have to keep any eye on them, and if it doesn't rain over the next few days I'll soak the trunks. I just hope there's no rot on the inside.
We'll see!
