In my retirement I am learning to graft.  Over the last few years I have 
grafted Minnesota varieties to hardy Bud 9 and Bud 115 rootstock.  These were 
for the 3a/b zone 50 miles north of Duluth, MN. Now my daughter may be moving 
and I may have to keep the grafted apples in zone 6a along the Ohio River.  
What can I expect from the performance of northern apples in a moderate 
climate?
