How to Plant and Grow Lisianthus
Plant Lisianthus Seeds: Sow lisianthus seed in cell packs or flats. Use a sterilized, soil-less mix. Press seeds into soil, do not cover. Kept at 70-80° F., germination is in 10-20 days. When 4-5 leaves have developed, transplant lisianthus seedlings into the garden, 6-8 in. apart. To encourage bushy growth, pinch back plants to the third node. Direct sowing of lisianthus seed is not recommended.
Grow Lisianthus: Full sun or part shade. Light shade in hottest climates. Lisianthus needs moderate water. Give regular moisture early in the season; avoid over-watering as plants become established. Does not like acid soil, does like regular feeding. Cut flowers are long-lasting.
