The callus helps prevent rotting when the cutting is placed in the rooting material. Place cuttings in a rooting medium of equal parts peat moss and sharp sand. Place in a sunny location and water occasionally. Too much water should be avoided. Pot the cutting after roots have formed.
Offsets are sections found at the base of the plant.
Rooted offsets can be separated from the parent plant and potted immediately. Unrooted offsets should be treated similarly to cuttings. Most species of cacti may be propagated from seeds. A simple way of germinating cactus seed is to spread the seed on the surface of moist, sterilized soil and barely cover with sand. Place the container in a plastic bag and seal.
