Seedling
2-3 weeksYoung plants develop 2-4 true leaves with a hairy stem. Seedlings are delicate and require consistent moisture.
Keep soil moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing once 2-3 inches tall.
Vegetative Growth
4-6 weeksPlants develop multiple stems and compound leaves. Stems become more robust and hairy. Height reaches 2-3 feet.
Maintain consistent watering. Apply balanced fertilizer at mid-growth stage. Support taller varieties with stakes if needed.
Flowering
3-4 weeksSmall, delicate flowers appear in axils along the stem, ranging from pink, red, or purple to white. Flowers bloom progressively from bottom to top.
Reduce nitrogen fertilizer to encourage flowering. Maintain moderate watering. Flowers attract pollinators.
Seed Pod Development
4-5 weeksFlowers fade and elongated seed pods form, containing numerous seeds. Pods turn from green to brown or reddish as they mature.
Reduce watering gradually. Avoid excess nitrogen. Monitor for pest damage to pods.
Harvest Readiness
1-2 weeks before harvestPods dry and become papery; seeds inside mature and develop full color. Pods naturally split or become brittle.
Stop watering. Allow plants to fully dry in the field. Check daily for shattering seeds.

Harvest Tips
Harvest when pods turn brown and begin to split naturally, typically 90-120 days after planting. Cut entire plant at soil level and hang upside down in a warm, dry location for 2-3 weeks to complete drying. Place a cloth beneath hanging plants to catch seeds as pods split and shatter. Thresh dried plants to release seeds, then winnow to remove chaff. Store dried seeds in airtight containers in a cool, dark location.
