Asparagus, a beloved springtime delicacy, tantalizes taste buds with its crisp texture and delicate flavor. But how long does this verdant vegetable maintain its peak freshness? The answer lies in understanding the factors that influence its shelf life.
Factors Affecting Asparagus Shelf Life

Moisture: Asparagus tends to wilt and lose moisture quickly. Maintaining high humidity levels around the spears helps preserve their crispness.
Packaging: Proper packaging plays a crucial role in keeping asparagus fresh. Loosely wrapping the spears in a damp paper towel or storing them in a perforated plastic bag allows for air circulation and prevents excessive moisture buildup.
