6-10 weeksFirst true leaves develop; plant slowly establishes root system and reaches 2-4 inches
Maintain consistent moisture and humidity; do not let soil dry out; begin fertilizing lightly with balanced fertilizer every 2-3 weeks
Vegetative Growth
8-12 weeksPlant develops bushy foliage with oval-lanceolate leaves; reaches mature height of 12-24 inches
