fruit tree trellising
I live in a temperate climate. I want to grow some fruit trees around my fence. To maximize varieties I want to train them on a trellis and to graft different varieties on the root stock. I have space for 3 trees, so I'm hoping for 8 different varieties. Is this possible? Do I need any special root stock?
