Grafting is something anyone can learn. Some species are easier to graft than others. The saying is “Apple is so easy to graft you can throw a stick at it and it will take”. Some of easiest species are apple, pear, and persimmon. One of the hardest to graft is heartnut. It is good to practice on easy to find wood before you do your first graft attempt. Practice always helps.
