Succulent propagation is an efficient and cost-effective method for expanding a plant collection or salvaging an overgrown specimen. Growing new plants from a cutting is particularly favored for succulents due to its high success rate and simplicity. This technique creates genetically identical copies of the original plant, avoiding the variability that comes with growing from seed. The process involves distinct phases that ensure the cutting develops the necessary structures to thrive independently.
Preparing the Cuttings
Select material from a healthy, mature plant, ideally during the active growing season of spring or summer. Choose a stem segment or a plump, undamaged leaf to serve as the cutting. Use a sterilized, sharp tool, such as a clean knife or scissors, to make a quick, clean severance that minimizes damage to the plant tissue.
For stem cuttings, aim for a length that allows one to two inches of bare stem below the lowest leaves for insertion into the soil. Gently remove leaves with a slight wiggling motion to ensure the entire base remains intact. This base contains the meristematic tissue where new roots and the “pup,” or baby plant, will form.
The Callousing Phase
Immediately following the cut, the vulnerable tissue must be allowed to dry and heal through a process called callousing. This step is necessary because the succulent’s water-storing tissue would rapidly absorb too much moisture if planted immediately. This absorption leads to rot and fungal infection, so the cutting must form a protective layer, similar to a scab, to seal the wound.
The callousing period typically takes between two and seven days, depending on the cutting’s size and ambient humidity. In humid environments, the drying process may take longer, sometimes up to a week. Place cuttings on a clean surface, such as a paper towel, in a dry, shaded area away from direct sunlight. Once the cut end has developed a tough, dry, and slightly puckered seal, it is ready for the next stage.
Planting and Initial Rooting
After a firm callous has developed, introduce the cutting to a rooting medium that is extremely well-draining to prevent water retention. A commercial cactus or succulent mix, often blended with grit, perlite, or coarse sand, provides the necessary aeration. Plant stem cuttings one to two inches deep into the soil, ensuring the lowest leaves sit just above the surface.
Leaf cuttings are typically laid flat on the surface of the soil, though some varieties can be placed upright with the calloused end barely touching the medium. Keep the cutting in a location that receives bright, indirect light during the initial rooting phase, as direct sun can cause the unrooted plant to dry out too quickly. Water sparingly, using misting or very light watering only after the callous has formed. This encourages the cutting to produce roots by seeking moisture.
Establishing the New Succulent
The rooting phase transitions into establishment once the new plant shows clear signs of growth. Successful rooting is indicated by the emergence of tiny white or pink roots, which may be seen at the soil line, and the appearance of new leaves or growth from the stem tip. A gentle tug on the cutting should also reveal resistance, confirming the roots have anchored into the soil.
The watering strategy must now shift from light misting to deep, infrequent watering, following the soak-and-dry method used for mature succulents. This involves thoroughly saturating the soil and then allowing it to dry out completely before watering again. The new succulent should be gradually acclimated to the higher light levels appropriate for its species, which prevents the plant from becoming “leggy” or stretched. Continued care focusing on full soil drainage and adequate light ensures the cutting develops into a robust, mature plant.
