Ask a Consulting Arborist Q&A: Bark and Trunk Concerns

Q: Maple trunk is splitting. Is it growing, or is there something wrong?

Q: Our maple tree's trunk appears to be splitting. Is it just growing, or is there something wrong with our tree? A bug? Disease?

A: The maple has suffered from "frost cracking" caused by severe cold that literally pops open the trunk when it has sap in it. The damage appears to be very bad and looks to have happened over several years. With such severe damage, the tree will suffer decay and possibly other damage from insects and disease and will probably never be healthy or structurally strong. Damage is likely to continue, as the maple is one of the most prone to this type of damage. The tree should be considered for removal and replacement with a more adaptable species.
