While a “frost crack” is the technical term, “exploding trees” is a bit more exciting. 🌳💥

As a deep freeze heads our way, headlines and social posts about "exploding trees" are everywhere, and although it can technically happen, the less exciting headline of “cracking trees” is usually more appropriate.

When it gets cold enough, the liquid sap inside trees can freeze. When this happens, the sap expands and puts intense pressure on the inside of the tree. If the tree can’t handle that much pressure, it physically cracks.

As you can probably imagine, cracking open a tree takes a lot of force. A loud cracking or popping noise often occurs when the physical crack forms. While these cracks can certainly be startling, a true "explosion" would be rare.

A large crack seldom kills the tree, but it can be an entry point for insects, bacteria and fungi that can contribute to eventual tree decline.

Property owners seeing a large crack in a yard tree are urged to consult an arborist to determine if there is a risk of the tree falling or dropping large branches.

Mother Nature is a force to be reckoned with.

We were able to pick this wind-damaged Spruce in one piece. Keeping the road open and the power lines safe.

This particular Spruce was directly exposed to west winds and failed into and hung up in an adjacent Spruce.

Videos and timelapse of this project coming soon!

Quick little Spruce this morning got the 🪓.

04/08/2025

This Red Oak lost a few large tops in the past and has a significant number of dead branches. Dead or dying tops are a common symptom of root issues as they are the most difficult place to deliver nutrients to. Upon further inspection you can see there is significant root decay. The root flare and buttress roots on the northern side of the tree are contrasted by a distinct lack of flare on the southern side. A common sign of girdling roots below the ground line. To keep the area safe for kids to explore, this Red Oak was recommended for removal.
