Japanese mustard spinach must be kept well watered throughout the growing period to reduce bolting and prevent flavour loss. Harvest young komatsuna leaves as required, picking only a few leaves from each plant. Alternatively allow heads to mature and harvest the entire plant as you would cabbage. If flower buds appear pinch them out to prolong cropping.
Alternatively sow komatsuna seeds singularly in module trays filled with good quality, moist seed-sowing compost. Place in a propagator or seal container inside a plastic bag at a temperature of 15-20C (59-68F) until after germination which usually takes 7-14 days. Once germinated, grow komatsuna plants on in cool conditions until all risk of frost has passed and they are large enough to plant outdoors at a distance of 30cm (12") apart. Water the plants thoroughly after planting. Sowings made in late summer will continue cropping into winter if protected by cloches, or if sown in frames, under glass, or in pots on the windowsill.
