I have a large, overgrown plum tree that produces a ridiculous amount of fruit.
It's been largely neglected for the past 2-3 years and is in need of a major haircut.
How hard can I prune it back? It is like 12-15 feet tall (branches growing straight up). I want to take off like the top third but don't want to kill it off.
Is there any way to encourage branches to form lower on the trunk?
Also, if anyone has any recipes for using up 20kg plums I would be grateful! Bonus points if there are any that don't require stoning first ...
