Brassica oleraceae var. chinensis. At only 15-20cm tall, this petite green has vivid white, succulent petioles and dark green, nearly round leaves. Dwarf White Stemmed pac choi have a mild, sweet flavour that works well in salads and stir-fries. Try adding thinly sliced pac choi to any noodle dish, or any vegetable soup recipe. Thin plants to 30cm so that they can grow to full size. Dwarf White Stemmed pac choi seeds may be grown from early spring to late fall, and the seeds do not require warm soil for germination. This variety forms nice, tight, urn-shaped heads with broad leaves.
How To Grow, Timing: All are cool season plants that grow quickly and then bolt. Direct sow with frost protection (a cloche or heavy row cover) as early as late winter, or without protection from four weeks before the last frost date to eight weeks after. Sowing short rows every 2-3 weeks allows for a fairly constant harvest time. Sow again in late summer, and provide frost protection as the first frost date approaches.
How To Grow, Seeding: Sow 3-4 seeds 5mm-1cm deep in each spot you want a plant to grow. Thin to the strongest plant at a spacing of 15-20cm between plants in rows 30-45cm apart.
How To Grow, Growing: Ideal pH: 6.0-6.8. 1 cup of complete organic fertilizer will provide sufficient nutrition to 3m (10′) of row. Choi Sum is harvested just before it flowers, so keep a close watch on each row. Pac Choi can be harvested at any stage, but if you want full-sized plants, watch for signs of bolting. Flower buds will appear at the centre of each plant, and a stem will form quickly as the plant turns from urn-shaped into a tall cone. Harvest as quickly as possible once flower buds are visible. Keep plants well-watered throughout their growth.
