I have had my property a little over 20 years. It was a old abandoned farm with about 50 acres of woods. 30 acres of way overgrown pastures (I'm guessing it wasn't farmed atleast 20 years prior to me buying it. The last 5 or so years I have found 7 decent sized wild apple trees buried in the tag alder. I have released them and they are producing a lot of apples now. Every fall I have taken a few hundred apples from my trees at home and throw them everywhere, along with dumping them into piles for the deer on this property. What are the chances that these trees are from the apples I just threw out? I have 2 growing near the road that I know I didn't put apples within a 100 yards. Is it a better chance that they brought in by birds? They are not old enough to be left over from the farmstead.
