The seeds of lobelia are very small and should be mixed with some dry sand to make sowing easier and to prevent the forming of clumps of seedlings that are difficult to transplant. Sow indoors in seedtrays filled with moist pottingsoil mixed with sand. Sow the seeds as evenly as possible and press them gently in the sowing medium. Don't cover the seeds up because this is a light germinator. Put the trays away in a light room with a temperature of 18 - 20 °C. Keep the temperature as even as possible and don't let the temperatures drop to much during the night. Cover the trays with a lid to keep the moisture inside.
Remove the lid when the seedlings emerge. Transplant the seedlings to separate pots filled with moist potting soil 4 weeks after the germination. Harden the plants of by putting them outdoors during the day or putting them in a cold frame during 10 days in the beginning of may. Put them outdoors on a sunny plot with free draining and fertilized soil in the middle of may, when there's no longer any danger of nightfrosts. Keep the plants about 10 - 15 cm apart. Lobelia doesn't tolerate drought and must be kept moist all times.
