Q.weeping cherry tree
The bark has a split about 1 foot down and is peeling away from the tree. Do I put something on it and wrap it or just wrap it? It was planted in May and seemed to be doing fine up till a few days ago.
This can be fairly common on thin barked trees, such as the Weeping Cherry Tree.
These type of bark injuries are not likely to be fatal to your tree, but can invite insects or disease.
In the past covering the wound was the care recommended, but that is no longer the case.
You can use a clean and sharp knife to clean up the edges of the split if needed. This can aide in healing.
The tree will attempt to heal by forming a callus over the cut edges.
If you see any signs of issues, I would use a Neem Oil application on the wound, but only if necessary.
Neem Oil works as both an insecticide and fungicide and is organic.
