Growing, Harvesting and Storage

Brassica rapa grows best in well-drained, loamy soil with a pH between 6.0 and 7.5, requiring full sun to partial shade for optimal growth.

It thrives in cool climates and requires consistent watering, especially during dry periods, but should not be overwatered to prevent root rot. Regular weeding and mulching help maintain soil moisture and reduce competition from weeds, while periodic hilling around the base of the plant can support root development. Harvesting should occur when the leaves are young and tender, typically 45 to 60 days after planting, by cutting the entire plant at the base with a sharp knife or shears.

For storage, the leaves should be blanched, dried thoroughly, and stored in airtight containers in a cool, dark place or refrigerated to preserve their potency and extend shelf life.
