Growing Licorice From Seeds
Licorice (Glycyrrhiza glabra) seeds require a little preparation to get ready for planting. Without proper treatment, licorice seeds germination rate is only around 20%. With proper care you can expect a 70-80% germination rate. Licorice is hardy in USDA hardiness zones 6 through 11.
Growing Your Licorice Seeds From Seed In 5 Simple Steps
# 1 | Place a handful of moist potting soil in a plastic bag and push your licorice seeds 1/2-inch into the soil. Place the plastic bag in your refrigerator. Check the moisture content of the soil in your bag each week, but only add water to keep the soil from drying out. Keep the seeds cold in the fridge for 60 days to break their dormancy. Take care to avoid saturating the potting soil in the bag with water during the chilling period.
# 2 | Remove the seeds from the potting soil in the bag after the 60 days. Rub your seeds on a sheet of sandpaper or rough stone several times to break the seed coat.
#3 | Choose a planting location for your licorice plants that will receive full sun exposure. Loosen and moisten the soil around the planting location. Use enough water to ensure that the upper 3-4 inches of soil is moist.
#4 | Push one seed 1/2-inch deep into the loosened soil. Cover each seed with a thin layer of soil but avoid compressing the soil. Seeds will germinate in 10-20 days.
