The Elephant Ear Succulent, formally known as Kalanchoe beharensis, is a unique plant recognized by its large, felted, gray-green leaves that resemble an elephant’s ear. This species is often confused with the tropical Alocasia or Colocasia plants, but Kalanchoe beharensis is a true succulent native to Madagascar. Propagating this distinctive plant is a straightforward process that allows gardeners to easily expand their collection. The method capitalizes on the plant’s natural ability to regenerate, but successfully growing new plants requires careful attention to sanitation and the specific needs of succulent tissue before planting.
Preparing Tools and Medium
Before taking any cuttings, gathering and sanitizing the necessary tools is important to ensure a clean process. Use a sharp, sterile instrument, such as a clean knife or a pair of gardening shears, which should be wiped with rubbing alcohol to prevent the transmission of pathogens to the parent plant or the cuttings. Cutting with a dull or dirty blade can crush the plant tissue, leading to a higher risk of rot and failure during the curing phase.
The choice of propagation medium directly influences the success of root development in succulents. A well-draining substrate is required to prevent water retention, which can quickly lead to the decay of the cutting. A specialized commercial mix formulated for cacti and succulents provides the ideal balance of aeration and drainage. Alternatively, one can create a suitable mix by combining standard potting soil with inorganic amendments like perlite, pumice, or coarse sand.
Timing the propagation to coincide with the plant’s active growth cycle helps maximize success rates. The best time to take cuttings is typically during the warmer months of spring or early summer. Choose a parent plant that is mature and exhibits robust health, as cuttings taken from stressed or diseased plants are far less likely to thrive.
Taking and Curing Cuttings
Propagation can be achieved using either stem or leaf cuttings, with the stem method often providing a faster path to a mature plant. When taking a stem cutting, locate a healthy section and make a clean cut just below a node, the point on the stem where a leaf or branch originates. The cutting should be approximately three to four inches long. Carefully remove the lower leaves from the stem to expose about an inch of bare stem that will be inserted into the rooting medium later.
Leaf cuttings are also a viable option and are taken by gently removing a whole, healthy leaf from the parent plant. It is important to ensure the entire base of the leaf remains intact, as this is where the meristematic tissue is concentrated. Since this tissue initiates root and shoot growth, a partial or damaged leaf base will significantly reduce the chances of successful propagation.
Regardless of the type of cutting taken, the next step is the curing process, which is vital for succulent propagation. The fresh wound must be allowed to dry completely in open air for several days. This drying period facilitates the formation of a protective layer of scar tissue, commonly called a callus, over the cut surface. Planting the cutting before this callus has fully formed allows moisture and microorganisms to enter the wound, resulting in rot.
The callousing process usually takes between three to seven days, though this timeframe can vary based on the humidity of the environment and the size of the cutting. The ideal location for curing is a dry area away from direct sunlight, allowing the wound to harden without drying out the entire cutting prematurely. Once the cut end feels firm and dry to the touch, the cutting is ready to be placed in the propagation medium.
Encouraging Root Development
After the callus has formed, the cutting can be shallowly placed into the prepared, dry succulent medium. For stem cuttings, insert the bare stem just deep enough to stand upright, ensuring the calloused end is in contact with the soil. Leaf cuttings should be laid flat on the surface or placed vertically with the calloused end barely touching the soil.
Providing the correct environmental conditions is necessary to encourage the dormant tissue to begin producing roots. Place the container in an area that receives bright, indirect sunlight, which provides the energy needed for cellular activity without scorching the delicate tissue. Maintaining a consistently warm temperature in the range of 65 to 75 degrees Fahrenheit further supports the metabolic processes required for root initiation.
It is necessary to withhold water immediately after planting the calloused cutting, as the new plant has no functional roots. Watering too early will dissolve the newly formed callus and expose the tissue to decay. Wait approximately four to eight weeks, which is the expected period for the first fine roots to begin to develop.
Once this period has passed, a very light watering regimen can be introduced, focusing on infrequent applications. Lightly misting the surface of the soil or using a bottom-watering technique provides minimal hydration without oversaturating the medium. The goal is to stimulate root growth by offering a slight moisture source while still encouraging the plant to seek water. After a few months, gently testing the cutting by giving it a slight tug will reveal if roots have anchored it into the soil. When the cutting offers resistance, the new Elephant Ear Succulent is ready to be transitioned to a larger, permanent container.
