I'd think, too, that up where he lives he'd need to give it a LOT
of winter protection so those new roots don't get damaged by the
cold. If I understand Larch (and I probably don't) they normally
need very little winter pampering. A new air layer will, I'd
think.

Some coldie please confirm for him??
