Using the silkworm food grater, grate enough mulberry food to lightly cover all the worms daily. This amount will increase as the worms get larger. For large worms you can also cube the mulberry food, feed only what the worms can eat in one day.
If using fresh leaves, feed enough leaves to cover the worms with a layer of 2-3 leaves. For smaller silkworms chop the leaves up with a knife and sprinkle enough leaves to lightly cover the silkworms. Use only the newly emerged soft leaves for newly hatch silkworms from eggs.
My worms are not moving are they dead? Silkworms do not move much, your worms are not dead. Silkworms will turn black when they die, and become deflated.
