Maple tree question #851195

Asked September 25, 2023, 3:27 PM EDT

Hello, I have a maple tree with a large crack up the trunk. I believe it is a crimson king maple about 20 years old. I really don't want to lose it, it is a great shade tree for my back porch. I am attaching pictures of the crack in it's trunk. Do you know what is causing the crack and what can I do to help it? The branches seem to be healthy. Thank you!

Thankyou for using Ask A Master Gardener! I really hate it when big beautiful trees crack like that, it makes me so sad.  Apparently, maple trees are prone to what is called frost cracks.  This occurs when temperature swings are severe. I found this article explaining the cracks.

I hope this helps to understand frost cracks!  Enjoy your beautiful tree!
