What should be noted when growing Gastrodia elata in boxes?
① You must choose high-quality fungus logs, preferably those with many young rhizomorphs distributed evenly.
② The fungus logs must be free of contamination by other fungi.
③ If there are not many rhizomorphs on the fungus logs, you may appropriately add some fungus branches or secondary or tertiary solid spawn of Armillaria mellea. You can also cover the fungus logs with a layer of culture substrate for cultivating Armillaria mellea (because the substrate contains Armillaria mellea, which acts as spawn).
④ If a piece of fungus wood is placed parallel 3 cm beside a high-quality fungus log, once the fungus wood connects with and grows Armillaria mellea well in the later stage, it can continuously supply nutrients to Gastrodia elata. But do not plant the Gastrodia near the fungus wood; plant it near the high-quality fungus log.
