The soil needs to be a well draining loam, which holds moisture. Ginseng definitely does not like wet soil!
Loose friable, light forest loam preferred. Soil quality affects the taste of ginseng. Organic matter 4 to 10% in the upper layer.
Modest water holding capacity in the top eight to twelve inches. Soil acidity should be between 5.5 to 6.5 Ph.
Ginseng likes a high organic and calcium rich soil. Raised beds 25cm to 30cm high. The most common point made by established ginseng growers, about successful ginseng cultivation, is to make sure that soil preparation is spot on!
