Frost tolerant

Bok choy can tolerate light frost, but exposure to cold temperatures in spring can trigger early bolting. In autumn, exposure to light frost can improve bok choy's flavor.


Mix a light application of a balanced organic fertiliser into the soil prior to planting.


Often planted with lettuce, mustard, kale, escarole, tatsoi, mizuna and other greens found in oriental salad mixtures. Miniature varieties are available for square foot gardens and containers.

Rows: 20cm (7") with 25cm (9") row gap (minimum)

Sow and Plant
