I have a crapapple tree that has shown some interesting behavior the
past couple years. Here's some history.

It's a fairly large tree, and when I got the house it was very lush. I
should have had it pruned then, as it turns out. In about 2000, a major
section split off from the main trunk and fell over. I had the whole
tree pruned and reshaped at the time, which reduced its size
considerably.

I was concerned over the following years that it might die, but it's
rallied and looks pretty good.

Now the odd part. Starting last year, one branch of the tree has
started to blossom in the fall. The last of them just fell off, so
figure around mid-September. This year's have set some fruit. I don't
know if the same branch blossomed in the spring when the rest of the
tree did, and as we had a spring freeze here I can't tell by looking
for mature fruit as they were all killed.

Has anyone heard of such a thing? To the best of my recollection, only
these two most recent years have shown this. The branch is close to the
driveway, so it's very noticable.

Sounds like a stress reaction from hard pruning. Temporary.
