Greetings!
We just recently moved to SD, and the previous owners of our house left us their two dead and two live apple trees. In the year that we've been here, the disease that seemed to have killed the two other apple trees has killed the smaller of the two apple trees that were still alive. We now only have one tree still alive, and the disease has begun attacking it.
Here are some pictures of the still-live tree, all three being of the trunk: (the black color isn't a shadow, I assure you. It's the tree's ailment)
And here is a picture of the most recently killed tree:
A friend suggested I spray apple cider vinegar water on it in case it is a fungus. My questions:
Is it too late?
Should I apply the apple cider vinegar water?
Also, I don't know the exact cultivar (I suspect honeycrisp), and I'm not sure if the cultivar's identity will help to save the tree. Just in case, I included a picture of a bloom from the tree:
I would appreciate it if any of you are able to save my apple tree!
