Silkworms are surprisingly picky eaters, with their diet almost exclusively consisting of fresh mulberry leaves. These leaves provide all the nutrients the silkworm needs to grow and spin a fine silk cocoon. In fact, their entire life cycle depends on having a steady supply of these specific leaves, which is why silkworm farming is often tied to mulberry cultivation. While they might nibble on other plants in a pinch, they’ll only thrive and produce quality silk on a mulberry leaf diet.
