The snake plant (Dracaena trifasciata, formerly Sansevieria trifasciata) is a resilient and popular houseplant known for its striking, upright foliage. Its ability to tolerate a wide range of indoor conditions, including low light, makes it a favorite among enthusiasts. Propagating this succulent is a straightforward process, allowing owners to multiply their collection using methods like division or rooting leaf sections.
Multiplying by Dividing the Plant
Division is the most reliable method for quickly creating a new, substantial plant and is the only technique that preserves the specific color patterns, or variegation. This process involves separating the underground stems, called rhizomes, which connect the individual leaf clumps. The entire plant must be removed from its container to access the root ball.
Once the plant is free, remove excess soil to expose the thick, fleshy rhizomes. Using a sharp, sterilized knife or shears, cut the root ball into sections. Ensure that each new division contains at least one healthy leaf or pup and an accompanying portion of the root system. Sterilizing the cutting tool prevents the transfer of plant pathogens.
Each separated section should be immediately potted into its own container using a well-draining soil mix, like one formulated for succulents. This method offers the fastest results because the new plants already have an established root structure. The new pots should be sized appropriately to avoid holding excess moisture, a common cause of root rot.
Rooting New Plants from Cuttings
Propagating the snake plant using leaf cuttings is an effective way to create multiple new plants from a single leaf, but it requires more patience than division. Begin by selecting a healthy, mature leaf and cutting it at the base of the plant using a clean, sharp implement. This single leaf can then be cut horizontally into several segments, each measuring between two and four inches in length.
Identify the bottom, or proximal, end of each segment, as roots will only grow from the part closest to the mother plant’s roots. Many growers make a small notch or an upside-down V-cut on the bottom edge; this serves as a visual marker and also increases the surface area from which new roots can emerge. Variegated varieties, such as the popular ‘Laurentii,’ will revert to solid green when propagated this way because the leaf cutting only contains the non-mutated green tissue capable of producing a new plant.
The cuttings can be rooted in either water or soil, but both require a period of drying, or callousing, for one to two days after the cuts are made. Allowing the cut surface to heal forms a protective layer that helps prevent the cutting from rotting when introduced to moisture. For water propagation, the bottom inch of the cutting is placed in a jar of water, which should be changed weekly to maintain oxygen levels and prevent bacterial growth.
When rooting directly into soil, the calloused cuttings are inserted about a half-inch deep into a porous, well-draining mix. Soil propagation is considered more stable and less prone to the rot that can sometimes occur in water. While water propagation allows the visual monitoring of root development, soil propagation bypasses the stressful transition from water to soil once roots have formed.
Post-Propagation Care and Transplanting
The success of new snake plants depends on the care they receive immediately following the propagation process. All newly potted divisions and cuttings should be placed in a location that receives bright, indirect light, which encourages robust root and leaf development. Maintaining a warm environment, ideally between 60°F and 80°F, is also beneficial for stimulating growth.
Divisions can be lightly watered immediately after repotting to help the roots settle into the fresh soil. Cuttings must be treated differently; if they were not allowed to callous for a few days, wait a week or two before the first light watering to ensure the cut end has healed. Overwatering newly propagated plants is the greatest risk, so allow the soil to dry out almost completely between watering sessions.
Patience is required, especially when dealing with leaf cuttings, which can take several months to develop a substantial root system and longer to produce the first small pup. For those who choose to water-root their cuttings, the transition to soil should occur once roots are about an inch long. Plant these rooted cuttings in a well-draining mix and water sparingly until they show signs of establishing themselves.
