Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds emerge within 7-10 days; seedlings develop first true leaves and establish root system

Keep soil consistently moist. Provide warmth (65-75°F preferred). Thin seedlings to proper spacing once 2-3 inches tall

2

Vegetative Growth

4-6 weeks

Plant develops branching stems, increases leaf mass, and grows toward full height of 1-2 meters

Ensure full sun exposure. Water regularly during dry spells. Light feeding with balanced fertilizer mid-growth. Stake tall varieties if needed

3

Flowering

3-4 weeks

Bright yellow flowers appear at branch tips and main stem; flowers are small but numerous and attract pollinators

Maintain consistent watering. Reduce nitrogen to encourage flowering over foliage. Pollinate manually if bee activity is low

4

Seed Development & Maturation

3-4 weeks

Flowers fade and seed pods develop; seeds gradually darken from light to dark brown/black over time

Reduce watering slightly to allow seeds to mature and dry. Monitor for pest activity. Avoid overhead watering to prevent fungal issues

5

Harvest & Drying

1-2 weeks

Seed heads dry on plant; seeds become fully black and hard, ready for collection and storage

Allow seeds to fully mature before harvesting. Dry harvested seed heads in warm, dry location. Thresh to extract seeds

Harvest Tips

Harvest seed heads when they are fully dry and seeds have turned black (typically 90-120 days after planting). Cut entire seed heads and dry further in a warm, well-ventilated location for 1-2 weeks. Thresh by rubbing heads between hands or against a screen to separate seeds. Store dried seeds in cool, dry conditions for up to 1 year.
