The Refrigerator is Stuffed With Discarded Onions.
When onions are kept in cold environments like the refrigerator, they are more likely to go bad. Mold starts to grow on onions as soon as they are exposed to water. If they are kept in the crisper, they will go bad more quickly because there is less air circulation in there.
Growing onions successfully requires a climate that is both dry and well ventilated. They should be stored in a bowl or bag made of mesh at room temperature. To prevent them from oxidizing, make sure they are kept out of the direct sunlight. Onions have a shelf life of up to three months if they are stored in the pantry.
