Allow the mature pomegranate plant to go dormant in the winter. The plant goes dormant when you do no see any signs of growth.
Select a stem for a cutting. Choose a firm, inflexible stem, 8 to 10 inches long and 1/4 to 1/2 inch in diameter.
Cut the stem off the plant using pruning shears or a thin, sharp knife. Remove any flower buds.
Coat the end of the cutting with semi-hardwood or hardwood rooting hormone.
Fill a container, 5 gallons or larger, with a potting mix containing 40% to 60% perlite.
Insert the cutting into the potting mix with the rooting hormone-coated tip pointing down. Leave 2 to 3 inches of the cutting's top exposed.
Maintain the cutting at 60 degrees Fahrenheit and keep the potting mix moist. Cuttings typically start rooting in eight to 16 weeks.
