Oooops......
I know the apple orchards in CNY have to deal with stuff like that regularly.
Once the fruit trees set their flower buds, a freeze will kill them and they have no crop as the trees will not set new flowers. So they have giant burners and fans to try to keep them from freezing during late season freezes and frosts.
You’re right about the burners and fans. The problem here was that we had temps in the mid-20’s for two nights. Much worse than a frost. We are praying for all fruit growers in this area!
