Q.Would you recommend a bleach bath for peaches?
Because of brown rot in our tree and on some of the peaches we had to pick the peaches early. Should we wash them in a mild bleach bath to kill any fungus residue that may be still on the peaches to give them time to ripen without them rotting first? Will they ripen inside if they are still fairly green? What do y’all recommend for spraying the trees to prevent this?

For an anti-fungal soak, I prefer vinegar - white or apple - a couple of tablespoons in a bowl of water, soak the peaches for 5 minutes. I soak all my fruits and vegetables like this before I eat them or cook them.
