Kolomikta. If that works, you might be able to use the existing roots to
grow another variety, and possibly dwarf the Argutas."
What I suspect would happen is something I saw happen with European
Plums grafted onto less than vigorous rootstock. The scions grew twice as
fast as the rootstock resulting in curious misshapen growths. Some tipped
over when the rootstock couldn't support the top growth. Bark tended to
split at the graft causing dry-out. If a similar thing happens with
Actinidia, it would definitely be a conversation topic.
