How should Gastrodia elata tubers be selected for use as seed?
Gastrodia elata tubers that are undamaged, free of pests and diseases, and not deformed are best for cultivation as seed. However, when seed is in short supply, tubers with minor damage can also be used for cultivation as seed after treatment. The treatment method is: first cut away the damaged part with a knife or bamboo strip, sun-dry the cut surface until it no longer exudes sap, and then plant it; generally it will grow as normal. When large white Gastrodia tubers are cultivated as seed, after 1 year they can become 1 large arrow tuber. When arrow tubers are cultivated as seed for asexual propagation, the "parrot beak"-like mixed bud at the top of the arrow tuber must be broken off, so that the arrow tuber will not produce an arrow (no longer bolt)
