TSOI-SIM - Chinese Green
Brassica campestris chinensis: A chinese vegetable that belongs to the same species as Taisai and Pak Choy but is used and grown like Hon Tsai Tai and Autumn Poem which is a flowering Pak Choy. The leafy, cylindrical, long stemmed chinese vegetable resembles the Brassica rapa group, and has very tender young stalks, delicious leaves and yellow flower buds-just like Italian Rapine fall strain. Use tender young leaves, stalks and delicious flower buds in stir-fries, salads and soups.
CULTURE: Although this year vegetable is tolerant to cool temperatures like Fall Raab it will bolt to seed quickly if outdoor temperatures change from cool to warm too fast. Therefore, you should wait until about 2 or 3 weeks before your last spring frost, before seeding Tsoi-sim outdoors, in May, so that early, fast growing young plants can enjoy gradual warming weather as it matures. Real hot weather at harvest time will spoil the taste. Most commercial growers prefer to sow Tso-sim outdoors about Aug 15-25th to mature in late Sept in gradually cooling weather conditions, like Fall Raab or Rapone. Make 2 or 3 sowings at 5 day intervals so that buds may be harvested before they open and stalks are young. Sow @ 5 seeds per ft/30cm in rows 2 ft/60 cm apart 0.25 in/6 mm deep, thin plants 8 in/20 cm apart. Tsoi-sim prefers not to be transplanted bare rooted. If you need to start an earlier spring crop indoors, sow seeds Apr 1st into peat pots and transplant the pot outdoors May 15th.
