Growth Stages

Seedling

2-3 weeks

Small plants with 2-4 true leaves emerge 7-10 days after sowing

Keep soil consistently moist but not saturated. Provide bright light if growing indoors. Thin seedlings to prevent crowding.

Vegetative

3-4 weeks

Plant develops larger leaves and a strong root system; main stem thickens

Apply balanced fertilizer every 2-3 weeks. Ensure consistent watering. Monitor for pests. Mulch around base to retain moisture.

Branching/Head Formation

2-3 weeks

Plant forms multiple side shoots and begins developing floret clusters; stems elongate

Switch to higher-nitrogen fertilizer to support head development. Maintain steady moisture. Begin checking for pest damage regularly.

Head Development

1-2 weeks

Florets cluster tightly on terminal and lateral buds; heads reach harvestable size

Continue watering consistently. Avoid overhead irrigation. Check daily for insects. Side shoots will develop if managed properly.

Harvest-Ready

Variable; harvest window 1-2 weeks

Heads are compact, firm, and bright green with tight florets; side shoots may be visible

Harvest when heads are firm but before flowers fully open. Morning harvest ensures best quality and flavor.

Milder and less sulfurous than common broccoli, Daqingmi works well steamed whole or lightly blanched. The thin stems are fully edible and tender. [source]

💊

Cruciferous vegetable nutrition

Medicinal

Like all broccoli, Daqingmi contains sulforaphane and other glucosinolates with antioxidant and anti-inflammatory properties. Rich in vitamins C, K, and fiber. [source]

Harvest Tips

Harvest the main central head when it is firm and dark green with tightly clustered florets, typically 2-3 weeks after flowering begins. Cut 5-6 inches below the head with a sharp knife. Side shoots will develop and can be harvested for 4-6 weeks afterward. Early morning harvest yields crispest heads. Harvest before florets begin to loosen and flower.

Fun Facts
