The String of Dolphins plant, Curio x peregrinus, is a unique succulent known for its cascading vines and leaves shaped like leaping dolphins. Its captivating appearance makes it a popular choice for hanging baskets and shelves, adding a whimsical touch to indoor spaces. Propagating this succulent is a rewarding and relatively simple process.
Why Propagate String of Dolphins?
Propagating String of Dolphins offers several advantages. It provides a cost-effective way to expand your plant collection without purchasing new ones. You can also share these distinctive plants with friends and family. Additionally, propagation rejuvenates older, leggy plants, creating a fuller, more vibrant appearance.
Tools You’ll Need for Propagation
Gather the appropriate tools for propagation: sharp, clean scissors or pruning shears for precise cuts. An essential small pot with drainage holes and a well-draining succulent or cactus soil mix are also needed. Rooting hormone is optional but can encourage faster root development.
Step-by-Step Propagation Methods
Taking Cuttings
Select healthy stems with plump leaves from the mother plant. Using clean, sharp scissors, cut a stem segment 3 to 6 inches long. Each cutting should include at least two to three nodes, as new roots emerge from these points. Remove leaves from the bottom inch or two of the cutting to expose the nodes and prevent rotting.
Allowing Cuttings to Callus
After taking cuttings, allow the cut ends to form a protective layer, called callusing. This prevents rot when cuttings are introduced to water or soil. Place prepared cuttings in a dry, shaded area for one to two days until the cut surface is dry and hardened. While optional for water propagation, callusing improves success rates.
Rooting in Water
For water propagation, place callused cuttings into a jar of clean water, submerging the exposed nodes. Filtered or distilled water is preferable. Change the water every few days to maintain freshness and prevent bacterial growth. Roots typically develop within one to two weeks; once they are a few inches long, transfer cuttings to soil.
Rooting in Soil
To root cuttings directly in soil, fill a small pot with a well-draining succulent or cactus mix. Insert the callused end of the cutting into the soil, burying the bottom nodes while keeping leaves above the surface. You can plant multiple cuttings in one pot for a fuller appearance. After planting, lightly water the soil to settle it around the cuttings.
Caring for Your New Cuttings
Once rooted, String of Dolphins cuttings require specific care. Place them in a location with bright, indirect light, as direct sunlight can scorch their delicate leaves. Maintain a consistent room temperature, ideally between 65 to 75°F (18 to 24°C). Water sparingly, allowing the soil to dry out completely between waterings to prevent root rot. As roots strengthen over the next few weeks, gradually acclimate young plants to slightly more light.
Troubleshooting Common Propagation Issues
You might encounter challenges during propagation. If cuttings fail to root, it may be due to insufficient callusing, leading to rot, or inadequate light conditions. Overwatering is a common problem, causing cuttings to become mushy and rot; ensure the soil or water is not constantly saturated. Slow growth often indicates insufficient light, prompting the plant to stretch and become leggy. Adjusting light, watering, and ensuring proper callusing can resolve most propagation difficulties.
