Now you're the smartest all around plant guy that I know, so I figured that I'd ask you this. We have an apple tree, the previous owners of the house took really bad care of it, but as soon as we moved in we took cars of all of the trees really well. But for two seasons, the apple tree would get blossoms but never any fruit. I've also been pruning it, but our trees tend to think of me as 'The Barber of Seville' when it comes to pruning. Anyway, this year I threatened to cut it down and move our Apricot tree to it's spot. Two weeks later, the apple tree is actually making fruit and a good amount.
So here's my question, what makes an apple tree make apples? I know it wasn't my threat, or was it?
