When sowing, take out the upper layer of the fungus bed, remove the soil from the lower layer, spread the withered and wet leaves on the lower layer, flatten it slightly, spread the seeds evenly on the leaves, cover with a thin layer of wet leaves, sow the second layer of seeds, cover the soil with 3 cm, cover with a layer of moist leaves, put into the soil layer of fungus, and finally cover the soil with 10 cm 15 cm.

Planting method of Gastrodia elata

1. Cultivation time: Gastrodia elata cultivation is generally from late October of that year to April of the following year.
