Seedling
2-3 weeksSmall paired leaves emerge; plant is delicate and low-growing
Keep soil consistently moist. Thin seedlings to proper spacing when 2-3 inches tall. Protect from strong winds.
Vegetative Growth
4-6 weeksPlant develops sturdy stem with numerous oval-shaped leaves along the length; bushy appearance
Maintain moderate watering. Apply balanced fertilizer every 2-3 weeks. Pinch off top growth if plant becomes too tall to encourage branching.
Flowering
3-4 weeksSmall, pale pink, lavender, or white tubular flowers appear in leaf axils, typically starting from lower stems and progressing upward
Continue moderate watering. Reduce nitrogen fertilizer to encourage seed set rather than excessive foliage. Ensure consistent warmth.
Seed Pod Development
3-4 weeksFlowers fade and seed pods (capsules) form, elongating and maturing into dark, hard shells containing seeds
Reduce watering gradually as plants mature. Support tall plants if needed. Monitor for pests. Pods will split when fully mature.
Harvest & Maturity
At maturity (day 90-120)Seed pods mature, turn brown-black, and naturally split open to reveal black seeds
Stop watering 1-2 weeks before harvest. Harvest pods when they begin to naturally split or cut entire plant and dry for seed extraction.

Harvest Tips
Harvest when seed pods begin to naturally split (usually 90-120 days after planting). Cut or pull entire plants and hang them upside down in a dry location to allow pods to fully mature and split. Alternatively, harvest individual pods by hand once they've turned brown-black. Collect seeds in a cloth or container placed beneath the drying plants. Store dried seeds in an airtight container in a cool, dark place for up to 2 years.
