General Culture:
Sow late spring through autumn. Thin to 6?to 8?apart with 12?to 18?between rows, in fertile, moisture-retentive soil. Lack of moisture at any stage during growth leads to premature bolting. Rosette pak choi (Tatsoi) is a cool weather crop and can stand light frost, but wet winter weather is not to its liking. Floating row covers are helpful.
Noteworthy Characteristics:
Tatsoi is believed to be of ancient origin. Tatsoi has very thick, lustrous black green leaves arranged in an attractive rosette of quite regular, concentric circles, with some prostrate and some upright. Crinkly, crepe-like texture and extremely dark, black-green leaves make this an attractive plant with potential as a handsome border for flower beds and ground cover.
Slugs, snails, cutworms, and flea beetles can be a problem.
Uses:
Like regular pak choi, tatsoi can be used at all stages: seedling leaves, small rosettes, large plants, and young flowering shoots. Young leaves and small rosettes are used raw in salads and stir fry. Rosettes can be harvested at 45 days.
