For sowing first fill a wide pot or seed tray with a good quality compost. Lightly but firmly flatten and consolidate the surface. Water the compost so that it is evenly moist all over. Take a pinch of seeds and lightly sprinkle the seeds over the compost surface. Do not cover. Needs light to germinate. To ensure germination high humidity must be provided this can be achieved by pacing a sheet of glass or clear plastic over the container. A clear plastic bag would work equally well.
