Problem with Maple Trees

Asked July 23, 2019, 10:40 AM EDT

We had a client email us about her two maple trees that are in her yard. "The bark is splitting of the trunk. It is almost 80% separated from the trunk. It’s leaves are already turning red and have been for at least 3 weeks." The client lives in town. I have attached 3 pictures for you to look at. Can you tell what may be happening and if there is anything she can do about it? Thanks,

Thank you for contacting Ask an Expert.

It is not uncommon to see bark splits on maples in our area. It usually is not harmful on a healthy tree but your client's trees may not be healthy. I would suggest an evaluation by a certified arborist. These look like they may be on the out lawn area and in most cities they would be owned by the city. Perhaps there is a city arborist who could evaluate them. It is difficult to diagnose a problem with only pictures which is why I suggest a visit from an arborist. Here are some links you might find useful.
