Description
Brassica rapa var. chinensis. Jade Spring choi sum seeds produce a short season, fast-growing hybrid variety of Yu Tsai Sum (or Choi Sum) that produces raw stems with the texture of lightly steamed asparagus, with a sweet, mild taste. Stems will be 5mm - 1cm thick if grown and watered well. Early spring plantings may bolt. The incredible flavour will have you eating it raw, straight out of the garden, before it can be cut for stir-fries, salads, or soups. The plants in our trials have been consistently uniform and show few signs of damage from pests or disease.

| Starting |
Sow 3-4 seeds 5mm-1cm (¼-½”) deep in each spot you want a plant to grow. Thin to the strongest plant at a spacing of 15-20cm (6-6″) between plants in rows 30-45cm (12-18″) apart. |
| 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. |
