Double grafting for apple belgian fence
I'm planning on putting in an apple Belgian fence next dormant season and want to make each leader a separate variety creating a multi grafted tree. At this stage I think I'll buy root stock and the scions and graft them myself. What I am worried about is fitting 2 scions onto a 1 year old rootstock. Is it possible to chip bud using dormant scion wood? Or should I slice the inside of each scion down so that they both fit on a cleft graft.
Any idea other ideas anyone has would be welcome
