The yucca is a popular houseplant because it is hardy and easy to grow. Its tall cane and crown of long green leaves provide a natural and low-maintenance decorative accent to any room in the house. The best way to propagate the yucca is with cuttings from the mother plant. These cuttings may be young side shoots or sections of mature branches growing from the main cane.
Use a sharp knife to sever a young side shoot from the mother plant. Be sure to cut close to the main cane so that the side shoot has a heel or enough woody bark from the mother plant to sustain root growth.
Apply a small amount of rooting hormone to the heel of the shoot to stimulate root growth, and then plant in moist potting soil.
Alternatively, use pruning shears to cut the trunk of a mature yucca branch into sections of at least 3 inches long. Mark the ends of the sections to show which end is the top and which is the bottom. This will ensure that the sections are planted with the top end up.
Allow the cuttings to dry out for three to four days by storing them in a cool and shaded location.
Apply rooting hormone sparingly to the bottom ends of the cuttings and plant them in moist potting soil.
The topmost section of the trunk, which has the crown of leaves, should also be allowed to dry out for a few days before replanting. Remove all the foliage leaving a few of the newest growths. With fewer leaves to sustain, the plant will be able to focus on root growth. Use a chainsaw to take cuttings from very thick yucca canes.
