Ceropegia bosseri is a distinctive succulent vine with a unique appearance. Often called “String of Sharks” or “Dolphin Necklace,” it features a trailing growth habit, making it an appealing choice for hanging displays. Its foliage features chubby, heart-shaped leaves resembling shark fins. Intriguing lantern-like flowers emerge periodically, adding to its charm. Originating from Madagascar, Ceropegia bosseri adds an exotic touch to any indoor plant collection.
Ceropegia Bosseri Care
Light Requirements
Ceropegia bosseri thrives in bright, indirect light. A south or east-facing window is often ideal. While it appreciates ample light, direct sun, especially during the hottest parts of the day, can scorch and damage its delicate leaves and stems. Insufficient light can lead to leggy growth, where the stems stretch and leaves become sparse.
Watering Needs
This succulent prefers a “soak and dry” watering approach; allow the soil to dry completely between waterings. Overwatering is a common issue leading to root rot, so err on the side of underwatering. During its active growing season in spring and summer, water every 10-14 days; reduce to about once a month or less in winter dormancy. Good drainage is essential; avoid letting the caudex (the swollen base of the stem) sit in standing water.
Soil Mix
A well-draining, airy substrate is essential for Ceropegia bosseri. A specialized succulent or cactus potting mix provides a suitable base. This can be improved by incorporating amendments like perlite, pumice, or coarse sand, which enhance drainage and aeration. The primary goal is to prevent water from pooling around the roots, as this can quickly lead to root rot.
Temperature and Humidity
Ceropegia bosseri prefers warm, consistent temperatures between 65°F and 85°F (18°C to 29°C) during its growing season. It is sensitive to cold drafts and temperatures below 50°F (10°C); avoid these. It adapts well to average household humidity levels; low to moderate humidity is generally sufficient. Avoiding extreme temperature fluctuations helps maintain the plant’s health.
Fertilizing
During the spring and summer growing season, Ceropegia bosseri benefits from occasional fertilization. A balanced, water-soluble fertilizer, diluted to half strength, can be applied once a month. Avoid high-nitrogen formulas, as excessive nitrogen can promote leggy, weak growth. Fertilizing should be avoided during the plant’s dormant winter months.
Propagating Ceropegia Bosseri
Propagating Ceropegia bosseri is straightforward, most commonly achieved through stem cuttings. Select a healthy stem and cut a section at least 4-6 inches long, ensuring it includes several nodes (the points where leaves and roots emerge). Allow the cut end to “callus” or dry for a day or two; this helps prevent rot when planted.
Once callused, it can be rooted in a well-draining soil mix or in water. For soil rooting, insert the callused end into a moist, well-draining substrate, ensuring at least one node is buried. For water propagation, submerge the node(s) in a glass of water, making sure no leaves are below the waterline to prevent rot. Roots begin to form within two to four weeks. Once the roots are a few centimeters long, the cutting can be transplanted into its permanent pot with appropriate soil.
Common Problems and Solutions
Root rot or mushy stems often result from overwatering or poor drainage. If detected, remove the plant from its pot, inspect the roots, and trim any dark, mushy, or unhealthy sections with sterilized shears. Repot the plant into fresh, well-draining soil in a pot with drainage holes, and adjust your watering schedule to allow the soil to dry out thoroughly between waterings.
Shriveling or wrinkled leaves often indicate underwatering. While Ceropegia bosseri is drought-tolerant, prolonged periods without water can cause leaves to lose their plumpness. To remedy this, provide a thorough watering, allowing water to drain completely from the pot, then adjust your watering frequency to ensure the soil doesn’t remain dry for too long.
Leggy growth (stretched stems and widely spaced leaves) is a sign of insufficient light. Moving the plant to a brighter location with ample indirect light will encourage more compact and robust growth. Pruning leggy sections can also promote bushier development.
Mealybugs and spider mites can occasionally affect Ceropegia bosseri. Regular inspection of the plant’s foliage helps in early detection. For minor infestations, a gentle wipe with a damp cloth or a cotton swab with rubbing alcohol can remove pests. Persistent issues can be treated with organic solutions like neem oil or insecticidal soap, applied according to product instructions.
