Hi all, as you may of seen in another thread I've just gained some new trees, 2 Acer pal's, a Metasequoia and an Acer Platanoides.

The trees were, let's say, 'well rooted' and they didn't have pots, the only pot's I could get hold of were too big for the rootball so there is a lot of air around it.

Now, my question is, will I need to protect the rootballs over the winter until I can work them and get them into a correctly sized pot, if so, to what extent.
