    Hello i have a flowering cherry tree kwanzan planted in a large pot but it has developed a brown scaly patch on its trunk which is spreading. I thought it could be canker but there isn't any gum or sap oozing out and when i scratch the surface of the infected trunk it still seems to be green underneath. Does anybody know what it could be and how to treat it? Thank you

    Certainly looks like canker, are there any leaves on the tree?

    You'll never have much success growing a tree of that size in a pot btw, they'll only last so long.

    I see from your last pic it hasn't ringed the trunk yet, once it does that the growth above will die. The branch which was broken or pulled off in your first pic was most likely the entry point for the disease.

    No guarantee but cutting out the affected area back to healthy wood is the way to go.
