Product ID: 3872
Very dark green komatsuna.
Compact plant with good heat and cold tolerance. Better uniformity and yield than open-pollinated varieties. Traditionally used in Japan either steamed and seasoned with soy sauce, or in stir fries and soups. It is also excellent braised or, at the baby leaf stage, used in salads. Avg. 9,600 seeds/oz. 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.
AVG. SEEDING RATE: For bunching: 1 oz./830', 1 lb./13,000' at above spacing.
SEED SPECS: SEEDS/OZ.: Avg. 12,650.
