Seeds germinate sporatically up to several months after planting. Use a sterile potting mix and bury the seeds to a depth of 2 seed diameters (8-10 mm). Keep the soil moist but not wet. Allow plenty of air circulation after the seeds have sprouted to help avoid fungal attack. These plants are quite prone to damping off (fatal fungal infection) when young, and many seedlings are lost.
Grow in partial sun till well established, but can be placed in full sun when the plants are more mature. Need adequate root space to prosper, so regular repotting is probably a good idea.
