In the last Pomona ,Fall 2009 Jim Noted that he has found if the Peach pit
does not freeze the tree won't be hardy. Is this because the seeds that are
not hardy don't survive the extreme cold to germinate or does it actually
increase the hardiness of the potential tree. I've often started hardy and
less hardy seeds just by giving the proper chilling ( in the Fridge which
does not freeze but will germinate earlier and can be started inside
earlier) because this gives my little tree more time to mature before it has
to harden off for the winter. This is a interesting observation. Any
further info on this topic Jim.
