I have a client that has an apple tree that was planted some years back (she says one hundred years ago - the house is almost two hundred years old). The apple tree is now rotten through the core. It is still alive, but it could easily fall with heavy rain or wind.
She wants us to cut the tree down, but she is very sad to have to do so as this species of apple tree no longer exists. I was thinking of somehow propagating the tree for her for no charge. If I succeed it will be great, if I fail no big deal.
Does anyone have any tips on how to go about this? I was thinking of attempting whip and tongue grafting. I am planning on using a piece of its own root to attempt this. Any advice?
