How to select and prepare the land with licorice
The rhizome of Glycyrrhiza uralensis has a strong germinating ability and extends horizontally under the surface to the surrounding of the old plant. One licorice can send out dozens of new plants in several years. Artificial cultivation, sowing for 3 years, new plants can be seen at a distance of 3 to 4 meters away from the mother plant. Its vertical rhizome can also take root, and the depth of the root system varies according to the soil quality and the depth of the groundwater table, generally within the range of 1 to 2 meters, sometimes up to more than 10 meters, with deep roots absorbing groundwater to adapt to arid environmental conditions.
