Generally
For short-term storage, oranges can be kept at room temperature on the counter for up to a week. For longer-term freshness—up to three to four weeks—store them in the refrigerator. It's best to keep them loose, in a mesh bag, or in a bowl with good air circulation to reduce moisture buildup and mold growth.
