Should I wait to replace that tree with a new one or soil is not affected by bacterial canker?

Is most of the damage south facing?

Unfortunately, not only.

To find out about involved details do a web search on bacterial canker of stone fruits.

Hi Embothrium, I did. I found hundreds of images and some looked somewhat similar and some looked different. That was the main reason why I decided to post this question here. I know a lot about figs but I am not that knowledgeable about plums or other stone fruit trees.

I know that young trees on Citation rootstock are susceptible to this disease. It was another clue.

However, I do not know. I hope it is not bacterial canker. I like this tree. It has a nice shape and produced great fruits last year and is blooming now. However, I also have a very young multi-bud pluot tree nearby and I do not want that one to get sick too.

My peaches in San Jose got canker in a lot of branch crotches. The fruit was still excellent and the tree vigorous. I just left it alone. My canker didn’t start like that time will tell though

That tree drowned to wet the young parts tree was dormant that part die as soon needs water.

gator_rider1, could you please give me more details. Do you think my tree does not have canker? Is there anything I can do at this point?
