Has This Tree Had Its Chips?
I have lived with my garden since 1982 and this Beauty of Bath Apple Tree was already established. I have noticed this affliction has struck it from time to time. I am hoping it's just a sign of the dry summer we are having. I have enclosed a photo of an example of a particularly unfortunate branch. Do you think it spells the death nell for what is obviously an old tree?
This is not necessarily a dire sign for the health and longevity of the apple tree. It could be from dry conditons, but more likely a fungal infection. If that is all, only one or two branches in the tree, then just prune them out and dispose of them. If the issue is more wide spead in the tree foliar canopy then a spray program with biological fungicide or 70% neem oil may be in order. Consider dormant spraying during winter if you are not doing that already.
