Passing on a lesson learned

[Orkine]

When you graft CHerimoya onto pond apple to use as interstock, graft as close to the main trunk as you can on the branch you pick.

I did a few grafts where I went further away from the trunk to find a point where the root stock and my scion matched in diameter.  I got successful takes and the cherimoya is growing vigorously. The cherimoya is growing so much faster than the pond apple and the branches are sagging.  If I let things go I expect a couple of them will snap.  I may have to stake them up and hope they gain enough strength to hold on to the grafted plants.  I don't plan on grafting on the cherimoya until next spring but at this rate I may have to try in the fall.

So for others doing this, consider grafts close to the trunk or alternatively cut and do a bark graft on the trunk instead of grafting on the branches.  You can then graft on the cherimoya branches.
