>From my experiments its no different EXCEPT if a bark graft is not under the
snowline, often even hardy varieties winterkill for me. Keep in mind this
is in -40C stuff. They apparently don't winterkill in milder climates.
However whip and tongue grafts of equal sized scions and branches from a
small trees seem fully hardy at extremely cold temperatures for me.

"Also I felt I needed to leave a few shoots that were on the trees base to
grow to feed the roots a little. Surely cutting a 5 " tree at near ground
level kills most of the roots?"

It probably does kill a lot of the roots. Its got to be a heck of a shock
to the tree, you would think. However, I've had great success with the
"cutting off at ground level and bark grafting" on trees 3" and less in
caliper. I did do some 4 and 5 inch trees this spring, about a week ago.
Worst case I figured the grafts wouldn't take on the 5 inch trees, and a
zillion root suckers would come up, and then I'd just regraft some of the
root suckers next spring. I'll let you know how grafting the 5 inch trees
works out for me. Keep in mind I'm doing this on really tough Ranetka and
Siberian Crab rootstock, not the dwarfing rootstocks.
