I just noticed that 2 of the four apples I bagged (don't laugh,
that's the biggest crop I've ever had) fell off the tree. We've had
a lot of rain and some wind, and I wonder if the mechanical "sail" of
the baggies might have pulled the apples down. The bags had almost
no water in them, so I don't think that was a problem.
It's possible it was just the tree dropping damaged fruit, since I
was too late at bagging and every fruit showed signs of significant
insect damage when I bagged them.
