Seedling
4-6 weeksTiny green leaves emerge; plant is fragile and slow-growing initially
Keep soil consistently moist but not waterlogged. Provide bottom heat (70-85°F) to accelerate germination (8-14 days). Use grow lights 12-14 hours daily.
Vegetative Growth
3-4 weeksPlant develops 2-3 sets of true leaves and builds branching structure; compact, bushy form characteristic of Japanese varieties
Transplant to larger containers when 2-4 true leaves appear. Harden off gradually before outdoor planting. Begin feeding with diluted liquid fertilizer every 2 weeks.

Fruiting & Development
4-6 weeksLong, slender purple fruits develop from pollinated flowers; fruits elongate to 8-10 inches with glossy purple skin
Thin to 2-3 fruits per cluster. Support heavy fruit-laden branches with stakes or cages. Maintain even watering and weekly feeding with balanced or potassium-rich fertilizer.
Harvest
