I've heard a lot of things:
- Pick them all on Labor Day.
- Set them on cardboard in the basement to ripen.
- Don't pick too soon.
- Don't pick too late.
- They must be chilled before the ripening process will start.
- Put them by ripe bananas.
My head is spinning from all the pear ripening information and I still am lacking one ripe pear.
Maybe our tree is a dud.
