This is the cherry plum I am trying to save in my new back yard (tree was overgrown with weeds for years and we just moved in an I have been restoring the backyard). Any help or suggestions would be awesome. So far I have not done anything except some pruning. Tree doesn't need the timber brace underneath but I have placed it there while I have been working.
If you're clearing a new garden and you want to plant other things,to be quite honest,I'd have the tree removed. It's only a matter of time till rain penetrating the fractured stump causes rot to occur (if it hasn't started already) and when it does, you may find the bough that is arcing off to one side suddenly falls. Sad though it may be, I'd recommend removing it and having the stump bored out to a depth of 12-18 inches, which should take care of any large roots left behind.
- Cut cleanly the part that I marked with red color in the photo so that the remaining surface is flat, but not horizontal, it should make rain go away from the tree (meaning from the trunk that is still alive).
Remove the leaves that are most damaged.
(optional) Hang some bird feeder, bird bath or similar ornament somewhere in the tree.
Leave everything to Mother Nature.
