What’s wrong with my non fruit bearing cherry tree?
5 year old tree. Healthy up till this year. Noticed a split in bark on main part of trunk 1 foot above ground. No blooms this year & very few leaves. Very nasty winter. Noticed similar trees in subdivision with same problem.
Your feeling about the severe winter are probably right. You may have a variety of cherry that's not as cold hardy as it could be. You might be able to repair damage, even at this date, as explained in this article: https://www.gardeningknowhow.com/plant-problems/environmental/tips-for-saving-cold-damaged-plants.htm
