We're testing alternative silkworm feed like mulberry leaf substitutes. Some use artificial diets with soybean powder or local leaves such as lettuce or loquat. It's tricky because silkworms are picky—they need specific nutrients and texture. But when natural mulberry runs low or you want cheaper, sustainable options, these alternatives help keep farming going. So far, results vary; some silkworms grow slower, others produce different silk quality. It's a work in progress.
