I have 2 M26 apple trees which are 5 years old and bush shape. Some of the branches are quite long for my small garden. Can I support them in some way so they start going upwards as opposed to side wards?
You could tie them in a similar manner as you would when growing as an espalier, but as opposed to growing them in a horizontal fashion! you could tie the in a " Y " formation, at least this way you control where the branches grow not the tree!
