The best method to start a crop of Lisianthus is from seed, although tissue culture and rooting of cuttings are also possible. Seeds germinate within 15 days at 25°C. During the first 60-90 days after germination, temperatures above 25°C should be avoided to prevent heat stress. The optimum temperature is considered near 10°-15°C. Seedlings should be transplanted before the stem elongates and root disturbance should be minimized to prevent wilting when the plants show visible buds. More than 60 days of 16 hours of long days are required to accelerate flowering by about 15-25 days. E-mail: plants@royalvanzanten.com
