Vertical cracks appearing in tree bark right now are usually a sign of drought stress, not disease, and Birmingham's shade trees are showing it after weeks of summer heat. ACE Tree Service is fielding more calls about this exact symptom this time of year.
Drought-stressed trees pull moisture from their outer layers first, and the bark can split as the trunk contracts under the strain. It looks concerning, but the tree isn't necessarily lost, what matters is how deep the cracking runs and whether other symptoms like early leaf drop are present.
Newly planted and younger trees are more vulnerable than mature ones and benefit from a professional look sooner rather than later. Our ISA Certified Arborist can tell you whether a tree needs deep watering, treatment, or just time.
