Thanks for the question.

Getting a broken branch to heal is not like getting a broken bone to heal. Just tying the broken branch back into its original position is no guarantee that it will fuse again with the main trunk. Taping it into place will certainly not hurt but has a strongly likelihood of not being successful. Applying any type of dressing or sealant is usually not recommended. Only time will tell. I’m reasonably confident that you will soon see on the reattached branch the leaves beginning to droop and turn yellow. Monitor what is happening in the reattached branch. Periodically scrape a small piece of bark away from the reattached branch. If the underlying tissue is green, the branch is alive and there might be hope for its survival. Once the underlying tissue becomes brown, the branch is dead and should be removed. You may have to continue doing this checking into the 2025 season.

If nothing else, consider having a professional, licensed arborist make an onsite inspection and assessment. Sometimes there is no charge for this.

The usual outcome for a situation such as yours is that the broken branch does not recover. At that point you will have to decide whether to completely remove the branch, which may negatively impact upon the tree’s overall appearance, or remove the entire tree and replace it. Might be a tough call.

You have a great tree, albeit somewhat uncommon. Too bad about what happened though there probably nothing that you could have done to prevent things.

Good luck. Thanks for consulting us. Get back to us with any other related questions.
