The Donkey Tail succulent (Sedum morganianum) is a popular houseplant celebrated for its striking, trailing stems covered in plump, tear-drop-shaped leaves. These stems can grow quite long, making the plant an excellent choice for hanging baskets. A notable characteristic is the fragility of its foliage; individual leaves easily detach when disturbed, which aids propagation. This succulent is exceptionally easy to propagate, allowing gardeners to multiply their collection from fallen leaves or stem trimmings.
Essential Preparation Steps
Successful succulent propagation begins with selecting robust material and preparing the cut ends correctly. Choose healthy, plump stem segments or individual leaves free from damage or disease.
The most important preparatory step is allowing the cuttings to dry and form a protective layer, known as a callus, over the detached area. This callousing seals the wound, preventing rot caused by pathogens and excessive moisture absorption. Depending on the environment, this drying period typically takes between two and five days. Once callused, place the cuttings on a porous, well-draining propagation medium, such as a commercial cactus mix or a blend amended with perlite or pumice.
Propagation Using Individual Leaves
Propagating the Donkey Tail from single leaves is a highly successful method, utilizing the plant’s natural tendency to drop foliage easily. To ensure a clean, whole leaf necessary for new growth, gently twist the leaf from the stem, ensuring the attachment point remains intact. The cells responsible for root production are located at the base of the leaf where it joins the stem.
After the leaf has calloused for a few days, lay it flat on the surface of the prepared succulent soil mix. It is not necessary to bury the leaf, but good contact with the medium aids rooting. Over the following weeks, small roots will emerge from the calloused end, followed by the formation of a tiny rosette, the new plantlet.
Propagation Using Stem Cuttings
Using stem cuttings offers a faster route to a more established plant. Begin by using a sterilized knife or shears to take a clean, angled cut from a healthy stem, aiming for a segment a few inches in length. Remove the lower leaves from the cutting to expose the nodes, which are the points where new roots will emerge.
Set the prepared stem cutting aside in a dry, shaded place to allow the cut end to form a callus over a few days. Once sealed, insert the bare portion of the stem directly into the propagation medium. Ensure it is deep enough to remain stable and upright. Securing the stem prevents movement, which can disrupt root formation. Within a few weeks, the cutting will develop a robust root system.
Nurturing the New Plantlets to Maturity
After the initial propagation phase, providing the correct environment is necessary for the new plantlets to thrive. Place the container in a location that receives bright, indirect light, as direct sunlight can scorch the new growth. While the cuttings are establishing roots, the soil should be kept slightly more moist than for a mature succulent, but never saturated.
Watering should be done carefully, using bottom watering or gentle misting, to avoid dislodging small leaves or overwatering the developing roots. Once the plantlets are visibly growing and have developed a strong root system, they can be treated like a mature Donkey Tail. Leaf-propagated plantlets can be transplanted once the original “mother” leaf has completely shriveled. Stem cuttings can be moved to a larger pot once they are firmly rooted and show clear signs of new growth.
