Frost Damage
Asparagus is a hardy perennial; however early-emerging spears may be subject to late-spring frosts. Varieties, such as Jersey Giant and UC 157, which break dormancy early in the spring, may be more susceptible to frost damage than ones with a longer dormancy period, such as Guelph Millennium.
Frost-damaged spears appear dark-green and water-soaked, often becoming limp and furrowed as they thaw. After a severe frost, there is often a delay before the crown develops new shoots, leading to gaps in the harvest schedule. Removal of the damaged spear from the plant may help to reduce this delay.
Freshly tilled soil, and low-lying areas are often more prone to frost damage.
