Regular watering and fertilization can promote healthy growth and prevent pests and diseases. With proper care, Wōsǔn can be harvested in as little as 50 days, making it a rewarding crop for gardeners and cooks alike.

Wōsǔn can be stored for up to 5 days in the refrigerator, but it’s best consumed within 2-3 days for optimal flavor and texture.
When handling Wōsǔn, avoid washing it excessively, as this can cause the leaves to become waterlogged and develop off-flavors.

If you’re having trouble finding Wōsǔn in stores, consider growing your own or substituting with other leafy greens. Some farmers may also offer Wōsǔn at farmers’ markets or through community-supported agriculture (CSA) programs. As interest in Wōsǔn grows, it’s likely that availability will increase, making it easier for cooks to access this unique and flavorful ingredient.
