Creating new succulent plants from existing ones is known as propagation, a simple process that allows gardeners to expand their collection without purchasing new specimens. Succulents are highly suitable for this method because their specialized anatomy allows them to store water and nutrients effectively. This inherent durability means they can survive and thrive even after a section is removed from the parent plant. Learning these straightforward techniques makes it possible to multiply a favorite plant easily.
Multiplying Succulents Through Leaf and Stem Cuttings
Propagation by cutting begins with selecting healthy plant material free of disease or damage. For leaf cuttings, gently twist the leaf from the main stem, ensuring the entire base remains intact, as new growth emerges from this point. Stem cuttings should be taken with a sterilized blade, making a clean cut just below a leaf node where growth hormones are concentrated.
After taking the cuttings, they must undergo callousing, a protective process against moisture loss and pathogens. The open wound dries out and forms a layer of scar tissue, preventing the cutting from rotting when placed in the soil. This period typically lasts between two to seven days, depending on the humidity and the thickness of the plant material.
Once fully calloused, the cutting is ready for the rooting medium, which must be highly porous and well-draining. A mix of standard succulent soil and perlite or pumice provides the necessary aeration without retaining excess moisture. Leaf cuttings are often laid flat on the soil surface, while stem cuttings are inserted shallowly into the medium.
Root formation is driven by plant hormones, such as auxins, which stimulate cell division at the wound site. For leaf cuttings, this often precedes the formation of a tiny “pup,” or plantlet, growing from the original leaf base. During this stage, the medium should be kept dry. The cutting relies on stored water and is highly susceptible to fungal or bacterial decay.
Initial establishment is complete once fine, white root hairs are visible, indicating the cutting is actively seeking moisture and nutrients. This rooting process can take several weeks to a few months, varying depending on the species and environmental factors like temperature and light exposure. The original leaf will eventually shrivel and fall off once the new plant is self-sufficient, having transferred its stored energy to the new growth.
Propagating by Division
A straightforward method involves propagating succulents through division, which relies on separating naturally occurring side shoots called offsets, pups, or “chicks.” These small plantlets form at the base of the mature plant, often connected by small stolons or growing adjacent to the parent. The advantage of this method is that offsets frequently possess their own rudimentary root systems, simplifying the rooting process.
A viable offset should be large enough to survive independently, typically reaching about one-quarter the size of the parent. To separate the offset, use a sterile, sharp knife to sever any connecting tissue cleanly. In many cases, a gentle twisting or wiggling motion is enough to detach it. Minimize damage to the parent plant’s root ball during separation.
Because these divisions often have existing roots, they require little to no callousing time before planting. The separated offsets can be potted immediately into small containers using a dry, fast-draining soil mix. This immediate planting allows the existing roots to quickly re-establish contact with the growing medium, reducing stress for the new plant.
Caring for New Succulent Starts
After a cutting has rooted or a division has been successfully potted, the focus shifts to establishing a care routine that encourages robust growth. New succulent starts require bright, indirect light to stimulate photosynthesis without damaging fragile, developing tissues. Placing them in a location with morning sun or filtered afternoon light prevents scorching caused by harsh, direct midday exposure.
The watering regimen for new starts differs significantly from that of established plants, especially during the initial rooting phase. While waiting for roots to appear, the medium should be kept mostly dry. Once roots are visible, the plant needs small amounts of moisture. This early watering is usually done by lightly misting the soil surface or applying a small amount of water around the base every few days.
Once the root system is established, the watering schedule should transition to the standard “soak and dry” method, though with less frequency than a mature plant. Allow the soil to dry out completely between waterings. Then, thoroughly saturate the soil until water drains from the bottom of the pot. This practice encourages the roots to grow deeper and stronger in search of moisture.
The choice of soil and container is a significant factor in the long-term health of the new start. A commercial succulent or cactus mix, often amended with extra inorganic material like coarse sand or perlite, ensures rapid drainage. The container must also have adequate drainage holes, as standing water is a primary cause of root and stem rot in young succulents.
When the plantlet has visibly outgrown its small starter pot, filling it with roots and showing multiple new leaves, it is ready for transplanting. Moving the rooted plant to a slightly larger, permanent home should be done carefully to avoid disturbing the newly formed root structure. The new pot size should only be marginally bigger than the current root ball to prevent the soil from retaining too much water.
