Peaches are basically introverts. They should be stored on their shoulders and not touch one another. If you must bag them, don’t put to many in one sack. And remember, they need to breath because of the ethylene gas they omit. So use paper (fridge only) or plastic with holes cut in it.
So how should you store them based on their ripeness?
Ripe peaches – If it’s ripe but you aren’t ready to eat it, put it in the fridge. You’ll need to check on it frequently though.
Not quite ripe – Store them on the kitchen counter, on their shoulders.
Firm peaches – Place them in a paper bag to ripen faster. Include a very ripe banana in the bag or an apple if you wish to speed up the ripening process.
