The cylindrical snake plant (Dracaena angolensis) is a unique and visually striking succulent. Its stiff, subcylindrical leaves grow upright, adding a distinctive architectural element to any space. This plant is popular for its low-maintenance nature and adaptability. This guide provides detailed methods to successfully propagate it.
Preparing for Propagation
Before propagation, gather tools and select a healthy parent plant. Spring and autumn are often preferred, especially for division, due to moderate temperatures and light.
Essential tools include:
A sharp knife or pruning shears
Rubbing alcohol for sterilization
Pots with drainage holes
A well-draining potting mix (e.g., cactus or succulent blend)
Rooting hormone is an optional addition. Sterilize cutting tools before and after use to prevent disease.
Propagating by Leaf Cuttings
Propagating from leaf cuttings can take several months. Select a healthy, mature leaf and cut it cleanly near the soil line using sterilized shears or a knife. Cut the leaf horizontally into 2 to 4-inch sections. Maintain the correct orientation of each cutting, noting which end was originally the bottom.
After cutting, allow leaf sections to callus in a warm, dry location for one to seven days until the cut end hardens. This prevents rot. For water propagation, place the callused end into a jar with a few inches of clean water. Position the jar in bright, indirect light and change the water weekly. Roots can form within one to four months.
For soil propagation, plant callused cuttings about a half-inch to one inch deep into a well-draining potting mix. Ensure the marked bottom end is inserted into the soil. Keep the soil consistently moist but not waterlogged to encourage rooting, which typically occurs within several weeks to months. Once roots are about an inch long, or new pups emerge, the cuttings are ready for potting.
Propagating by Division
Division is a faster propagation method that helps maintain variegation. This method is best performed when the plant is mature and has produced multiple rhizomes or pups, often during repotting in spring or autumn. Carefully remove the plant from its pot, shaking off excess soil to expose the rhizomes and roots.
Identify natural divisions within the root system, where the plant can be separated into two or more sections, each with its own leaves and roots. Use a sharp, sterilized knife or pruning shears to cut through the rhizomes, ensuring minimal root disturbance. Each new section should have at least one healthy leaf and some roots.
Once divided, plant each section into a new pot filled with a fresh, well-draining succulent or cactus potting mix. Choose a pot size that accommodates the roots and has drainage holes. Water the newly potted divisions lightly to settle the soil, avoiding excessive moisture. Place the plants in bright, indirect light.
Caring for New Snake Plant Propagations
Once cylindrical snake plant propagations have developed roots or been successfully divided and repotted, providing appropriate care supports their continued growth. New propagations thrive in bright, indirect light, such as near an east or north-facing window, which encourages root and leaf development. While snake plants can tolerate lower light, optimal growth occurs with sufficient indirect light exposure for about five to six hours daily. Direct, harsh sunlight can scorch young leaves, so it is best to avoid it.
Watering newly propagated plants requires careful attention; allow the soil to dry out completely between waterings to prevent root rot, a common issue for snake plants. Water deeply until water drains from the bottom of the pot, then discard any excess water. Young plants are particularly susceptible to overwatering because their root systems are not yet fully developed. Maintain temperatures between 65°F and 80°F (18°C-27°C) for best results, as extreme cold can hinder growth. Fertilization is generally not necessary for newly propagated plants; wait until they are more established before considering a light feeding during the growing season.
Common Propagation Challenges
Several issues can arise during the propagation of cylindrical snake plants, stemming from environmental factors or improper technique. Rotting is a frequent problem, primarily caused by overly moist conditions, which create an environment conducive to fungal or bacterial infections. To prevent rot, ensure cuttings are properly callused before planting, use well-draining soil mixes, and avoid overwatering, especially in water propagation methods where changing the water weekly is important. Poor airflow around cuttings can also contribute to rot, so ensure good air circulation.
Failure to root or slow growth can occur due to insufficient light, incorrect temperatures, or a lack of patience, as snake plants are known for their slow growth rate during propagation. Providing bright, indirect light and maintaining consistent warm temperatures can encourage rooting. If cuttings are not rooting, it may simply require more time, as some can take up to four months to develop roots. For divided plants, transplanting shock can sometimes lead to temporary wilting or slow establishment; minimizing root disturbance during division helps alleviate this.
