Canning peaches in stages
Can I peel/slice peaches one day and can them (whole peaches and peach salsa) the next?

You could, but the quality of the peaches would not be as good. Peaches will brown once the peeled or sliced peach is exposed to air. If you did peel/slice on one day, store them in the fridge in a solution of 3 grams (3,000 milligrams) ascorbic acid (vitamin C) to 1 gallon of cold water.
