Corms are harder compared to bulbs. Yes, it is possible. Natural vegetative propagation occurs by means of roots, underground stems, subaerial stems, aerial shoots, leaves and bulbils. Corms can be propagated by cutting the corm into sections and planting. The young corm, at first about the diameter of the flower-stalk, grows continuously, till in the following July it attains the size of a small apricot. For example, Tuber of potato, the rhizome of ginger. The storage organ may look like a bulb, but it has no layers like a true bulb. The chamber is well watered immediately after planting.
