New to owning Apple trees. I have three red apples trees in zone 6b Michigan in this area of the property. Previously property was neglected for 30 years but tree is still very much producing according to neighbors.
Height of trees are 2 and 3 stories tall. Adjacent 3 story Barn used as direct reference.
I did a basic health pruning on 2 of the 3 trees so I would have a control sample of the changes I made 1 month ago. Washed tools in between each tree. This tree was not pruned. What do we think is going on here ? Recent Hot and Humid weather x 1 week.
We can say this is Tree #3 - my control.
Tree #2 - Beginnings of tent caterpillar on one branch which was pruned off back two bifurcations. There was a white line running along to the point of first bifurcation from tip of branch end. Disposed of debris in a bag and washed tool.
Tree #1 - seems to have no health issues to my eye.
