Rootstock propagation by root cuttings?
Anyone know if any fruit trees can be propagated with root cuttings? Right now I have apples and cherries. I'd eventually like to try my hand at grafting but I don't want to accidentally mess up one of my existing trees.
I heard that taking root cuttings is a fairly easy process, just get access to the roots, take some small pieces of pencil width roots and plant them in the ground.
I just don't know if this process generally works for fruit trees though. Has anyone tried this out or have any info about it?
