About the variety

Beka Santoh is a loose-heading Japanese Chinese cabbage maintained in the open-pollinated seed trade. Kitazawa describes vigorous growth, pale frilled leaves and white petioles. The supplier supports its use in Japanese soups and sukiyaki; an exact introduction date is not documented here.

Starting seed

Sow 1/4-1/2 in. deep for mild spring weather or late-summer planting. Keep moist at 60-70 F; allow about 4-10 days to sprout. Thin to 12 in. apart, rows 18 in. apart. Use sun and fertile soil; prolonged cold or heat may trigger bolting.

Care through the season

Maintain even moisture and remove weeds while small. Rotate brassica beds and use insect netting before flea beetles or caterpillars arrive. Grow for a cool harvest; extended cold on young plants can induce flowering, and summer heat can reduce leaf quality. Fall sowings often avoid spring cold followed by heat.

Harvest and use

Cut tender leaves or whole loose heads about 25-40 days from sowing; harvest before flower stalks rise. Refrigerate and use promptly. To save seed, keep several healthy plants and isolate them from other flowering Brassica rapa; collect dry pods before they shatter.

Saving seed

These open-pollinated brassicas are insect-pollinated. Keep several healthy, typical plants for seed and prevent crossing with other flowering varieties of the same species. Some plants need a cold period before flowering. Let pods mature, then cut and dry them under cover before they shatter; clean, label and store seed cool and dry.

Common problems

Check young leaves for flea beetle holes, aphids and caterpillars. Use row covers early, inspect regularly, and remove badly diseased plants. Crop rotation, drainage and steady watering help limit root disease and stress. A flowering stem means the leafy harvest is ending; use the leaves promptly.
