Sun scalding and frost cracking are similar and occur during the colder months, but sun scald is typically less severe. A sharp drop into freezing temperatures can result in cooling rapidly within the bark. Destroying developing tissues of the inner bark, especially when frosts and freezing temperatures occur during early autumn just before dormancy or in late spring when dormancy has ended. Direct sunlight onto the bark during winter months can also cause the tree to slip out of dormancy. Sun scald may happen at any time of the year, but damage via sun scald is typically more severe during cold weather. Damage may not be noticed immediately after scalding has occured. Injured bark will appear as sunken with discoloration, cracking, and peeling. Check back for preventative tips.
