      Fill 4-inch pots with a mixture of perlite and peatmoss. Place the pots in a container of water until the top of the soil is visibly moist.

      Sow one seed in the center of each pot. Push the seed into the soil to a depth that is twice the diameter of the seed. Cover the seed with the peat moss mixture and gently firm in place. Do not pack the soil hard or the seed won't germinate.

      Cover the pots with a clear sheet of plastic and place the pots in a bright area, out of direct sunlight. A south-, east- or west-facing window provides the right amount of light. Check the soil for daily moisture. If the soil feels dry, give it warm water. Remove the plastic when the seeds germinate.

      Water the soil to keep it evenly moist. The water should be warm to the touch.
