Bacterial canker cherry
I’m fairly sure this is bacterial canker on our cherry tree-what would you do about it? My book tells me to cut out the infected material but as it is a fairly young tree with a slender trunk (which is where the infection is) I think this would barely leave enough healthy trunk for support. I was hoping it might fight back over the summer but it just seems to have spread. Is it a goner? It is a shame, pretty tree which gave us ten delicious cherries this year 😢.
