Green 70 D Improved
Asian Green Seed
Product ID: 4031
Heat-tolerant choi sum.
Very similar to Gunsho, just a few days later to mature. Choi sums are among the most popular vegetables in Hong Kong, Taiwan, and China. The stems are a vibrant bright green, very sweet and tender, and are usually harvested just before, or as the first few buds are opening. The stems regrow for cut-and-come-again harvest. Excellent in stir-fries, steamed, or in soups. Avg. 200,000 seeds/lb. Packet: 250 seeds.

CULTURE: Sow from early spring through midsummer. May be sown into late fall in mild climates or when overwintering in a high tunnel or other protected structure. For full-size bunching: sow 15 seeds/ft., 1/4" deep in rows 12-18" apart. Most varieties do not require thinning; see individual product descriptions for varieties that do. For baby-leaf production of 'Tokyo Bekana', which is the only "Asian green" we recommend for baby leaf, see the Baby Leaf Brassica Greens culture.
SUCCESSION PLANTING: Sowing every 7-10 days will provide a continuous harvest of both budding/cutting and heading types.
INSECT PESTS: Flea beetles are best controlled by covering with floating row covers from day of sowing.
HARVEST: Budding/cutting types (choi sum and kailaan): harvest when the buds are just mature, or a few are just blooming. Multiple harvests are possible for these types. Heading types (celtuce, Chinese cabbage, and komatsuna): may be harvested from medium to full-size, depending on local market preferences. These types are suitable for single harvests.
