greatest unanswered mysteries of fruit trees
I think it's been a bit dull here lately so maybe this will liven things up a bit. Let's hear your observations of strange and mysterious fruit tree behavior, things that you have no logical explanation for, and see if anyone else can diagnose or at least theorize what's going on. I'll start with this...
Uneven fruitset- Why do some trees set all their fruit on just a couple of branches where the fruit is all clustered up and the entire remainder of the tree is barren? I've often seen this happen with apples and European plums.
A similar question I put out last year was about same variety trees (Damson plums) a few feet from each other that had born similarly the previous season but in the current season one tree was barren while the other was loaded with fruit. Never got what I considered a very satisfactory theory for that one.
I welcome answers and new questions.
