How do you raise silkworms?

It is generally recommended to raise silkworms in spring, when the weather is warm and mulberry leaves are high quality, giving higher survival, faster growth and more silk. Silkworm diet is mainly mulberry leaves; for white silkworms, from the 3rd-5th instar you can mix silkworm feed with leaves until cocooning; for colored silkworms, use differently colored feeds. When changing leaves, move them very gently with a feather or soft brush to avoid injury.
