How to store blueberries
Sort the moldy blueberries from the fresh ones.
Look for berries that have white, fuzzy mold and toss them out. The mold can be found around the stem area.
You will also want to discard any berries that are too soft or wilted looking; they are too ripe and will rot quickly. Sorting the bad berries from the good ones will prevent mold from spreading.
