Planting Instructions:
This seed should be sown directly outdoors since the long roots of this plant need space to develop and dislike being disturbed. After the last spring frost when the soil has warmed to 70-75°, plant several seeds together 1" deep and 6" apart in rich, well drained soil. The seeds will begin to germinate in 1-2 weeks. Thin to the strongest seedling per grouping. The use of a netting or screen can be useful to prevent birds or animals from eating the seeds as they develop. Keep soil moist.
