Root "transplant"

[Isitangus]

Quick question-during root pruning, if I have a good size root that is just in the wrong spot/overlapping another root etc, rather than simply chop it off, can I transplant it into another spot. I imagine I would drill a hole of similar size, insert cut root, seal with cut paste and done? I would leave a number of fine feeder roots into the larger transplanted root/s.
Would this work?
I know one way to find out is just to do it but I'd rather succeed at something rather than fail and risk the plants health for fear of not asking the question.
Any feedback welcome.

Roots can be grafted Angus but it usually takes a little more than

drill a hole of similar size, insert cut root, seal with cut paste and done

Like any other graft you need to ensure cambium contact between stock and scion (in this case tree and root)
I have grafted roots on crabapple using wedge graft technique but only a few survived my clumsy first attempt.

I would say it would be worth a try. If your graft fails it is likely that new roots will start from the wound as the hole starts to heal so either way you win.

Very hard without an active upper tree growth

You woud be better to cutt your root off and the tre that as a root cutting 5this year, then grafting it back on next year when you can ensure it will survive.
Although with root grafting, there is no need to use the same tree as the parent.
