Found this on NPR.  A way to make a tree not require so many chill hours for fruiting.

That is interesting. Chill hours necessary for synchronized blossoms for pollination is now off because of climate change. Go figure.

They are attempting to influence when the male trees blossom with horticultural oil, with unpredictable, hit and miss results.

Maybe they should buy 100 acres in each of the next Zones heading north and  . . . .

Thank you for the interesting post.

Interesting. Seems to me that part of their problem is they have monocropped all the exact same hybrid. I think a mix of cultivars would have slightly different bloom times and more chance of synchronized pollination. They are trying to force monocrops to behave, whereas I prefer to mimic nature.
Interesting...
:D
