Cutting a stem from one plant to create another plant is a process known as propagation. This is not only the simplest way to grow a hibiscus plant but also ensures that the new plant is identical to its parent. Since hibiscus cuttings do best when taken from new or softwood, take cuttings from an established hibiscus in spring or early summer.
Find a leaf node on the hibiscus plant that is at least 5 to 6 inches from the tip of the selected stem. Use pruning shears to make a straight cut just below the leaf node.
Remove all the larger leaves on the stem but allow a few of the smaller leaves to remain at the top. Dip the bottom end of the stem into rooting hormone.
Fill a 6-inch garden pot with a 50-50 mixture of moist potting soil and perlite.
Create a hole in the center of the soil with your finger. Put the hibiscus stem into the hole and press the soil back into place.
Cover the hibiscus stem with a clear plastic bag or use a clingy plastic wrap to cover the pot and stem. Take care to ensure that the bag or wrap does not place too much pressure on the stem.
Set the pot in a partly shaded area that remains out of direct sunlight. Check the soil every few days to ensure that the soil is still wet.
Spray the soil with water from a spray bottle as needed. Do not allow the soil to completely dry. Roots generally appear in about eight weeks. Transfer the stem to a larger pot and continue to water.
