It depends on your needs.

Blueberries are berry-shaped and have strong storage resistance. It is best to put fresh blueberries in the refrigerator immediately after purchase. The best storage temperature is 1~3°C. If you want to eat fresh blueberries, never place them in a refrigerator below 0°C. It is not recommended to wash blueberries with water and then put them in the refrigerator, because the moisture can easily cause the blueberries to rot, so keeping the surface of the blueberries dry is a way to prolong the freshness of blueberries. First, wrap the plate of blueberries completely with plastic wrap, vacuum pack them, and then cover them with a plastic bag. Or place the dried blueberries separately on a layer in the refrigerator. Do not place them together with odorous foods to prevent odor contamination.

When the refrigeration temperature drops, transfer the blueberries into a plastic bag and store them in the freezer. “This way, the original flavor can be preserved for two weeks without changing.
