Seedling
2-3 weeksTiny seedlings with two round cotyledons emerge; first true leaves are small and slightly purple-tinged
Keep soil warm (70-75°F) and moist; provide bright light; thin seedlings to prevent damping off
Vegetative Growth
3-4 weeksPlant develops sturdy stem with increasingly dark purple leaves; bushy growth pattern
Pinch off top growth to encourage branching; maintain consistent warmth and moisture; fertilize every 2-3 weeks with balanced fertilizer
Pre-flowering
2-3 weeksPlant becomes fuller and more aromatic; purple flower spikes begin to form at stem tips
Pinch off flower buds to extend leaf harvest and maintain flavor intensity; continue regular fertilizing
Flowering
3-4 weeksSmall purple or white flowers appear on terminal spikes; foliage production slows
Harvest leaves frequently to delay flowering; allow some flowers for seed production if desired or remove for continued leaf vigor
Seed Production
3-4 weeksFlowers mature into seed pods containing small black seeds
Allow select flowers to go to seed; collect seed heads when dry and brown; save seeds in cool, dry conditions for next season
