poor limb attachment angles (narrow crotches). In other cases it looks like proper techniques for limb removal were not followed and the tree had a hard time sealing over the resulting tree wound. If this tree had been trained 50 years ago to a single (and taller) trunk with wide-angled lateral limbs many of these wood rots could have been avoided.
Later in my trip to Georgia, I came across an orchard with the largest collection of poorly trained trees I have ever seen.

|No central leader|

|Narrow crotch may lead to split trunk in the future|
