First prepare the soil by adding compost or aged manure then dig in well. Make a wide trench with the trowel. Water the bed well the day before planting then don’t water again until the seedlings have emerged.

- Plant the Seed
Plant the seed ½ inch (12mm) deep and 8 inches (20cm) apart along the trench. Seedlings will emerge in 10 to 14 days.
After the seedlings emerge water well. Fertilize with liquid fertilizer 2 weeks after the seedlings have emerged then every 2 weeks for the best results.
