I have alot of branches to graft on the tree I am considering to graft ,so I will make different combinations and see what works. I am now considering of adding one or two apple varieties also, and a branch or two of pure medlar . I imagine it as a frankentree ,will be quite interesting .
I am still not sure if a can graft both the desired plant variety and the interstock at the same time, say pear - medlar -apple like in the same day ,dunno If I explained it clear enough ☺☺😀
As for the varieties ,all of the plants I will be taking the grafts from are unknown varieties to me, so I guess in a way this will be mostly an experimentation . The thing is I already have the apple tree of unknown variety , and if I will use the apple variety winter banana as interstock I would have to buy a plant just for the experiment, but I may do just that if thats the best chance of having pear grafted onto apple .
