Hello! Can you help identify what is going on with my dwarf honey crisp apple tree? I recently noticed the bark seems to be eroding away. I've looked online.....is this some type of canker? I have not been doing any spraying. The tree is approximately 5-6 years old (planted ~3 yrs ago) and this spot goes about 1/2 around the tree. I looked the rest of the tree over and the 2nd picture is the only other thing I saw of possible concern....some cracking where the tree was grafted...not sure if this is a concern or not. If you could give your best guess what the first picture is, how to treat it, prevent it....and if this is too far gone and I should replace this tree or is there hope to treat and recover to make it a productive tree. Two years ago it had a bunch of delicious apples. Last year it had only a few blooms and no apples....based on some online reading I assumed it was because I pruned it pretty hard the previous winter. I was hoping for a bounce back year with more delicious honey crisp this year!
