Why does an apple stop potatoes from sprouting?
Apples, as part of the ripening process, give off ethylene gas, and this gas promotes the sprouting of the spuds, whereas, early on, it was claimed that ethylene gas prevented sprouting. Potatoes, as well, will cause the apples to get mushy and moldy more quickly.

What’s the difference between new potatoes and old potatoes?
New potatoes are just normal potatoes removed from the soil before they were fully matured. In contrast, normal potatoes are potatoes that were allowed to grow up completely before harvesting them. New potatoes are way smaller, have a higher water content, and are less resilient than normal potatoes.

Fruits and vegetables, FIRM
Cut off at least 1 inch around and below the mold spot (keep the knife out of the mold itself so it will not cross-contaminate other parts of the produce). Small mold spots can be cut off FIRM fruits and vegetables with low moisture content. It’s difficult for mold to penetrate dense foods.
