How is white asparagus grown?
White asparagus, known for its delicate flavor and white color, is not a different type of asparagus but rather green asparagus that has been grown in the absence of sunlight. To achieve this, asparagus spears are covered with soil or other materials as they emerge from the ground. Without exposure to sunlight, chlorophyll production is inhibited, resulting in the distinctive white color.
The process of growing white asparagus is labor-intensive and requires specific conditions:
- Soil: Asparagus prefers well-drained, sandy soil with a pH of 6.5-7.0.
- Planting: Asparagus crowns (the root systems) are planted in trenches and covered with soil.
- Darkness: Trenches are gradually filled in with soil or other materials such as black plastic, straw, or hay to block sunlight from reaching the spears.
- Harvesting: White asparagus is ready to harvest when the tips of the spears begin to break the surface of the soil. It is typically cut just below ground level.
Growing white asparagus can be more challenging than growing green asparagus due to the extra care required to prevent greening. However, the unique flavor and appearance of white asparagus make it a prized delicacy.
