Will grapefruit mould and how long?

Answer 1

Yes, grapefruit can mold if stored improperly or kept for too long. Typically, if kept at room temperature, grapefruit may start to show signs of mold within a week or two. In the refrigerator, they can last longer, usually up to three weeks, but it's important to check for any signs of spoilage regularly. Proper storage in a cool, dry place can help extend their freshness.
