Growing Environment of Ganoderma lucidum:

Ganoderma lucidum usually grows in mountain forests with high humidity and dim light, and it mainly grows in the roots of rotting trees or their trees, not on the branches of pines and cypresses, as described in some literary works.

Reishi is not a plant and cannot photosynthesize on its own, but can only take in nutrients from other organic matter or decaying trees. Ganoderma lucidum is a hard, sporny and slightly bitter large fungus. When it reaches maturity the reishi spews out powdery spores which reproduce.

Nowadays, wild reishi is rare and the quality is not easy to control. Today, Hainan Island in China produces the most abundant strains of reishi, and most of them are grown artificially in the market.

More famous artificial cultivation of Ganoderma lucidum in mainland China is Wuyi Mountain in Fujian Province. In Taiwan, the more famous Ganoderma lucidum producing areas are Taipei, Shiding and Hualien.
