The Silver Dollar Vine (Xerosicyos danguyi) is a succulent vine known for its distinctive coin-shaped leaves along cylindrical stems, earning it names like Silver Dollar Plant or String of Coins. Originating from Madagascar, this vining succulent is popular for its appealing appearance and straightforward care. Propagating it allows for expanding a collection, sharing, or rejuvenating an existing plant.
Preparing for Propagation
The most suitable time to propagate is during the plant’s active growing season, typically mid-spring through summer, ensuring optimal conditions for root establishment. Essential tools include sharp, clean pruning shears or scissors for precise cuts.
For the rooting medium, a well-draining succulent or cactus soil mix is ideal, providing necessary aeration and preventing waterlogging. Rooting hormone, while not strictly necessary, can improve success and speed up root development. When selecting a section for cuttings, choose a healthy, mature, firm stem with several leaves, as new, soft growth may not root effectively.
Propagating Silver Dollar Vine
Propagating is most effectively done through stem cuttings. Take a cutting typically 4 to 6 inches long, ensuring it includes at least a few sets of leaves and several nodes. Make a clean cut just below a leaf node, where roots are most likely to emerge. Remove leaves from the bottom third of the cutting to expose these nodes.
After taking the cutting, allow the cut end to “callus” or dry out to prevent rot when planted. Place cuttings in a dry, well-ventilated area away from direct sunlight for at least two days, or until a dry scab forms. If using rooting hormone, dip the callused end into the powder before planting. Plant the prepared cutting into the well-draining succulent soil mix, burying the bottom nodes. While water propagation can initiate roots, transferring to soil after roots are 2-3 inches long is generally recommended for long-term establishment.
Caring for New Cuttings
Place newly planted cuttings in a location that receives bright, indirect light. While the parent plant tolerates full sun, young cuttings are sensitive and can scorch in intense direct sunlight. An east or west-facing window often provides ideal light.
Watering needs for new cuttings differ from mature plants. Allow the soil to dry out completely between waterings to prevent rot, as overwatering is a common cause of failure. When watering, ensure the soil is thoroughly moistened, then allow excess water to drain. Silver Dollar Vine thrives in warm temperatures, ideally between 60 to 80 degrees Fahrenheit, and prefers medium to low humidity. Fertilization is not necessary for newly rooted cuttings. Signs of successful rooting include new leaf growth and gentle resistance when lightly tugged.
Troubleshooting Propagation Challenges
If cuttings begin to rot, it is most often due to overwatering or insufficient callusing. Ensure the soil dries out between waterings and that the cut end has fully callused for at least 24-48 hours. If the cutting becomes mushy and discolored, remove it to prevent further spread of rot.
Cuttings may sometimes fail to root if unhealthy, the temperature is too cool, or there is insufficient light. Providing consistent warmth and bright, indirect light can encourage root development. If leaves shrivel or turn yellow, it might indicate underwatering or too much direct sunlight. Check soil moisture and adjust watering frequency; if leaves are plump but yellowing, it could be a sign of excessive light.
