Fill a seed starting tray with potting soil. Water until the soil is moist. Insert the seeds just below the surface of the soil.
Set the tray in a greenhouse or a portable propagator. Keep the soil moist to the touch. Once the seedlings have sprouted, you can transplant them to individual 4-inch pots. This will take about two weeks. Keep the seedlings indoors for the first winter.
Remove all weeds from the planting site in the spring. The site should have constantly moist soil and receive full sun or partial shade.
Dig planting holes that are twice the width of the plant's containers and just as deep. Remove the plants from their containers, and lower one into each hole.
Firm the soil around the base of the plant. Water until the soil settles. Continue watering frequently enough to keep the soil moist at all times.
