[Apple-Crop] Pick Your Own Apple Freeze Damage

[Win Cowgill]

Kurt- Apples will begin freezing at about 28F- if the event is 4 hours or longer significant damage will occur.

Fruit that experienced only a mild (~28°F or above) freeze of short duration (less than 4 hours) may recover and be perfectly salable, but should not be considered candidates for long-term storage. If this is the case, wait until the fruit thaws out the next day before harvesting.

Note: Temperatures in the low 20’s and teens will make the fruit unsalable.
I have been guiding the growers I work with in NJ, NY and PA to have all fruit harvested by Friday pm if they wish to sell it.

Daytime highs on Friday are expected to be only 34 and on Saturday 41.  We would love to be able to maintain some apples on our trees until Thanksgiving for PYO uses only.  Do any of you have any experience with this?  Will the apples maintain a sufficient amount of quality to be able to be marketed to a rather non discriminating PYO cliental following the freeze event with the expectation that the apples will be used quickly for fresh use and not stored?  Are these apples suitable for cider?
