Pak Choy (Pak Choi)
Sow in full sun during the cooler months and part shade during the hotter months. Pak Choy grows quickly in a rich, moist soil. Mulch to conserve moisture and water regularly. 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.
