Locust Tree Bark Splitting and Dead Branches: Heat, Drought, and Proper Pruning

A locust tree showed bark cracks with reddish wood underneath, dead branches, and a history of sucker removal seven years prior. The owner asked if pruning now was safe and what caused the splitting.

Answer: Environmental Stress and Maintenance

Extreme heat and drought cause bark cracking. Dead branches can be pruned any time. Steve recommends deep watering: apply 1 inch of water (measure with a pan under sprinkler) every third day for two weeks, then weekly unless heavy rain occurs. This supports recovery and reduces further stress.
