I've had my Crimson Queen since she was just a stick (Graft from Ebay) and she grew before my eyes, and at one point planted her in by backyard. Recently during a storm, a huge branch from another tree fell on her and broke about 90% and left 10% by nearly thread. I did not have the mental strength to try to put together what was lost. Fast forward about two weeks, I am thinking of taking some steps to try what's possible. -As an immediate action, I have thread grafted one of the tiny branch from whats alive to the rootstock. I will wait to see if that works out, but meanwhile, I have another thought and that's where I need your help. I also have a Red Filigree that's growing for the last 2.5 years without much progress on the size (I know they are extremely slow grower, so I'm just letting it grow in the backyard). Will it make any difference in the growth rate if I attempt 'Thread Graft" with the Red Filigree to the rootstock Crimson Queen was Scion to? My plan would be to move the Red Filigree to a pot, thread graft against the injured Crimson Queen's Root stalk and if it takes, keep the Red Filigree's non grafted part, later take crimson queen part still stuck to the tree off and turn it into a bigger Red Filigree? Is it possible?
