Zulfiqar - I think you will get more meaningful input if you start a dedicated thread. Certainly seems like you have a significant issue.
My guess is that what you have is canker caused by the bacterial pathogen pseudomonas syringae. All of my heirloom cherry trees got it and all of them survived. However, Iâm in zone 8b, so the mild climate probably helps the trees recover.
I half-jokingly call this âice blightâ because the bacteria facilitates ice formation within the wounds so it can further invade the tree. I donât fully understand all the details but if you google pseudomonas syringae ice nucleation you can learn more. If you have cold winters and you really want to save the tree, you could make an insulating sleeve with rockwool (rodents donât like it) around the affected area during the cold months.
I posted this pic in another GF discussion the other day, but itâs pertinent here too. You can see what a severly infected cherry tree looks like when it heals the canker wound.
Thank you sir for replyingâŚ
Thanks for sharing, Zumo. I will look up that pathogen and its treatment. Iâm in 5B/6A, so it gets pretty cold here reasonably often. The good news is that this tree is in a large container on wheels, so I can roll it in the garage.
