Ripening green apples from downed tree
The applesauce I made is good and tart but an unappealing green.
Dixon County Nebraska
I think it is too early in the season for the apples to ripen off the tree. At this time they are still growing and storing starch for when they ripen. Closer to ripening they will ripen if exposed to ethylene, a ripening hormone, given off by ripening fruit such as bananas. You could put a ripen banana with them, but I suspect they will just shrivel up.
