Start with Dang Shen as a simple perennial root crop for beginners.
Seeds or young plants, a garden fork, compost.
Plant in early spring or late summer for best results.
Choose a well-draining soil with plenty of organic matter. Ensure containers are at least 30 cm deep.
Direct sow seeds 2-3 cm deep, or plant young plants about 15 cm apart in rows 60 cm apart.
Keep the soil moist and mulch lightly to retain moisture. Watch for signs of damping off.
Water regularly, especially during dry spells. Fertilize with compost tea every 4-6 weeks.
Prune dead foliage in late winter to encourage new growth and prevent disease spread.
