Lisianthus - Key Growing Information
SOWING: Transplant: Greenhouse production is highly recommended. Sow 12-13 weeks in deep cell packs before last frost. Light is needed for germination, but a fine layer of vermiculite covering the seed will help control algae growth. Keep the soil evenly moist, but not saturated and maintain 70-75°F (21-24°C) soil temperature. Provide good air circulation until emergence. Reduce moisture levels once emergence has occurred and allow to dry out slightly between waterings to prevent algae growth. After emergence, reduce the temperature to 60-70°F (16-21°C). Avoid stressing the plants with high temperatures over 85°C (29°C) and overwatering during this stage to prevent rosetting (the resting stage). Early transplanting is recommended. Transplant no later than the fourth leaf stage, approximately 55-60 days. Direct seeding is not recommended.
