Examine the carrion for a healthy stem. Cut or pull away a piece of a stem close to the base.
Set the cactus piece aside allowing the cut end to callous over. The end must be dry and sealed over. The length of time the end takes to be calloused over depends on the humidity in the air and the thickness of the cut.
Fill a 6-inch pot two-thirds full with cactus mix, or mix your own with equal amounts of potting soil and perlite. Over the top of the soil, add 1 inch of sand. Leave the drainage holes uncovered because you want the water to drain through the soil quickly
Insert the calloused end into the sand. Firm the sand down and around the stem with your fingers to hold the cutting in place.
Fill a container with 3 inches of water and place the pot into the water. Soak the pot in the water until the top of the sand is visibly moist.
Allow the pot to drain out excess water. Place the pot in a warm bright window.
Water the soil thoroughly two to four weeks later. An indication that the carrion needs water is to look at the stem. If it looks as if it is shriveling it needs water. Water the same as you did in Step 5. Wait another two to four weeks before watering again. It takes three to six weeks for the roots to form.
Feed the carrion with liquid fertilizer once a month. Mix and apply according to label directions.
Place it in full sun in a room that maintains a temperature above 55 degrees Fahrenheit.
