A larger, leafier version of Tatsoi, Yukina has a more robust, upright habit producing big wrinkled leaves. Able to withstand both warm and cool conditions. Use it in stir-fries and steamed.
Greens in the cabbage family need rich soil with some lime for a pH of about 7.5 and adequate water so the growth is never checked. A good cover of mulch will insulate them from hot, dry spells of weather. Their most damaging pest are the caterpillars of the white cabbage butterfly. Dipel, derris dust and pyrethrum are all effective organic controls for these voracious pests.
