Cracks in tree trunks, stunted leaf growth and thin canopies are all signs your tree is struggling. Diagnosing the cause of the symptoms is the first step in improving your tree’s health.
Several factors can cause bark on trees to crack and peel. Trees planted too deep and pruned with flush cuts are more subject to frost crack and sunscald.
Girdling roots can also result in stunted growth and dieback on trees. These circling roots place pressure on the expanding trunk and stop the flow of water and nutrients between the roots and leaves. It is usually a flattened trunk, decline or other above ground symptom that indicates there is a problem below ground.
Physical injury to the trunk or improper pruning can also result in poor wound closure. Proper care is about the only option at this point. Make sure the tree is properly watered and mulched to reduce further stress.
A bit more information: Consider contacting a certified arborist when these types of problems arise. These tree care professionals inspect the tree, evaluate its condition and recommend possible treatment options, including the removal of a hazardous tree.
