Apple tree problems
I purchased two bareroot apple trees this spring: a Haralred and a Honey Crisp. Attached are photos of the issue I am trying to identify. Both trees are showing the necrosis, while none of my other apple trees are. As can be seen, it is the new growth which is most affected. There is brown necrosis on some of the leaves, while the other new leaves are malformed, curled, and eventually dying. I have looked closely for insects but cannot find any.
Can you help me identify this problem so I can take corrective action?
