Plant in a sunny spot which receives at least six hours of sun and ensure the ground is well moist before planting. The seeds also need oxygen to germinate, hence too much water in the soil would literally drown the seeds to death.
If possible, soak the seeds the night before planting to make sprouting a little smoother. This should, however, not worry you too much.
Plant four to five seeds in a small circle around the centre, spacing them about 15 to 20cm apart. Do not sink the seeds more than one inch into the soil; just enough to block light and hide them from birds.
