Fill a seedling tray with moistened potting soil. Sow the talinum seeds on the soil surface, spacing them 2 inches apart in all directions. Press on the seeds lightly so they are in full contact with the soil, but do not bury them, as they require light to germinate.
Mist the soil surface with water, using a spray bottle. Cover the tray with clear plastic and set it in a sunny area where temperatures remain between 70 and 75 degrees Fahrenheit.
Remove the plastic and mist the soil with water as necessary to maintain a moist growing environment. Talinum seeds take up to 30 days to germinate.
Remove the plastic once the first seedlings appear. Water when the soil surface feels dry.
Transplant the seedlings outdoors after all spring frost danger has passed. Space the plants 12 to 16 inches apart so they have room to spread as they grow.
