What does the silkworm baby eat besides mulberry leaves? Can you raise silkworms all year round?

In the earliest spring, you can give him some bitter vegetables before the mulberry leaves germinate, but the silkworm baby still doesn't want to eat them ~ ~ If the tussah also eats tussah leaves, the general silkworm only likes to eat mulberry leaves, and the other leaves basically won't touch ~ ~

In autumn and winter, when the temperature is not high, silkworm eggs will not hatch and there will be no leaves. Generally, you can raise silkworms in spring, summer and early autumn, and it will be over after a year of cold weather.
