The best time to sow is March and April when the soil is rich with organic matter and ready for the summer ahead.
Propagating licorice is easy. It can be propagated from cuttings, division or seeds.
Growing Licorice from seeds
Soak the seeds for at least 24 hours in lukewarm water and then sow seeds in seed starting mix, which you can make yourself from these seed mix recipes. Sow the seeds at a depth of 1/2 inch. Cover the seeds with soil and keep it evenly moist until the seeds germinate. Germination occurs within two weeks. Optimum germination ranges around 68 F (20 C). Leave space of 2 feet between each plant.
