It is best for it to live symbiotically with the white mushroom family fungi Armillaria mellea and Mycena osmundicola, so that the seeds can sprout, form round corms, and grow into healthy Gastrodia elata tubers. Mycena osmundicola provides nutrients for seed germination, and Armillaria mellea provides nutrients for the protocorm to grow into a Gastrodia elata tuber.
2. Choosing the planting site
For planting Gastrodia elata, it is best to choose gently sloping land and valley gully land that is half shaded and half sunny and rich in organic matter.

During the tuber enlargement period, spray the medicinal material Gendaling solution on the leaf surface, which can promote the transport of leaf photosynthetic products (nutrients) to the root system, improve the nutrient conversion rate and the ability to loosen soil, make the rhizome expand rapidly, and greatly increase the content of active substances. In the high-temperature summer season, use shade nets or branches to shade and cool the plants, and prevent trampling by people and livestock.
