Wow, I'd be interested in learning to do that for other trees, could be a lot of fun with certain fruit trees.
I know my step dad has the most amazing old pear tree. This thing is about 40 ft tall and over 100 years old. It has just loads of pears that fall in the winter and are ripe in winter when there is snow, so you never worry about bugs since he is in Michigan with it.
If I could get a graft of that to grow, would be pretty awesome.
You should get a graft of that to grow. I grafted some on my old plum tree onto some wild plums here.
This is a short video I made of what works for me.
