In the spring I grafted an exiting wild apple on my old apple tree. Unfortunately the grafting has died, although it seemed to grow callus and connect in early summer. Did I store the twigs for grafting under bad conditions? Did I do a technically lousy grafting? Did some happy little bird clean its beak and break the graft? I don’t know, and it shall not keep me from grafting some other time. It’s funny, and does a grafting take on it’s great.
I’ve been told, that some professionals now have grafted this wild apple, to learn if it deserves to be grown in plantations or gardens. If it is a healthy tree, I’m sure we will get access to it for our gardens, at least from some of the specialised nurseries.
