The Elephant Bush (Portulacaria afra) is a popular succulent cherished for its woody stems and small, fleshy leaves, making it a favorite for indoor cultivation, bonsai training, and warm-climate landscaping. This resilient plant naturally develops a dense, shrubby form, but without intervention, it can become leggy and lose its attractive shape. Pruning is a necessary maintenance task that not only controls the plant’s size but also actively promotes a healthier, more compact structure. Regularly removing growth allows the plant to redirect its energy, ensuring it remains a vigorous specimen.
Why and When to Prune
Pruning the Elephant Bush serves several horticultural purposes, primarily focusing on managing its size and promoting dense foliage. Targeted cuts prevent the plant from becoming overly elongated or “leggy.” Removing the tips of branches encourages lateral branching, which results in a much bushier, more compact appearance. Pruning also allows for the removal of any dead, damaged, or diseased stems.
The best time to perform significant pruning is during the plant’s active growing season, generally spanning from late spring through early fall. Pruning during this period ensures the plant recovers quickly and produces new growth rapidly. Light maintenance, such as pinching off soft tips, can be done year-round whenever a stem is beginning to stretch.
Essential Pruning Techniques
Before beginning any cuts, prepare your tools to minimize stress and potential infection to the plant. Always use sharp shears, scissors, or pruners that have been sterilized with rubbing alcohol or a bleach solution. Clean tools ensure a smooth cut, which allows the wound to heal quickly and prevents bacteria or fungal pathogens from entering the plant tissue.
The two main techniques used for shaping the Elephant Bush are “pinching” and “cutting back.” Pinching involves removing only the soft, new growth at the very tip of a stem, often just using your fingers or a small pair of scissors. This minor removal immediately signals the plant to activate dormant buds lower on the stem, resulting in the development of two or more new branches from that point.
When a more drastic size reduction is necessary, perform a “cutting back” operation by slicing further down the stem. Make the cut just a few millimeters above a leaf node or a branch junction, as these are points where growth hormones are concentrated. Cutting slightly above a node directs the plant’s energy to that specific point, promoting the rapid emergence of new shoots. A clean cut allows the succulent tissue to dry and form a protective callus quickly, which is the plant’s natural defense against moisture loss and infection.
Utilizing Cuttings for Propagation
A practical benefit of pruning the Elephant Bush is the opportunity to use the removed material to start new plants. Healthy stem segments from the pruning process root very easily, making propagation a simple and rewarding conclusion to your shaping efforts. Cuttings ranging from two to six inches long are ideal for this purpose, though even smaller pieces often take root successfully.
After taking the cutting, allow the cut end to dry out and form a protective layer, known as callusing. This process typically takes between two to seven days, and it is a necessary step to prevent the cutting from rotting once it is placed in soil. Once the cut surface is dry and sealed, the segment can be planted in a well-draining succulent soil mix or placed in water, though the soil method is generally considered more reliable.
New cuttings should be kept in bright, indirect light and should not be watered until new roots have formed. With proper conditions, root development can begin in as little as one to three weeks, at which point you can begin treating the newly rooted plant like a mature specimen. This ease of propagation means that a single pruning session can quickly expand your collection of Elephant Bushes.
