String of Dolphins: A Comprehensive Care Guide for the Unique Succulent
Origin and Description
String of dolphins, scientifically known as Senecio peregrinus, is a captivating succulent native to Africa. Its distinctive folded leaves resemble leaping dolphins, giving it its charming common name. As a popular houseplant, string of dolphins is prized for its trailing vines and delicate foliage.
Care Requirements
Light: String of dolphins thrives in bright, indirect sunlight. Place it near a south-facing window or provide supplemental lighting with grow lights if necessary. Avoid direct sunlight, as it can scorch the leaves.
Soil: This succulent requires well-draining soil to prevent root rot. Use a commercial cactus/succulent mix or create your own by combining potting soil, pumice or perlite, and sand in a 2:1:1 ratio.
Water: String of dolphins has drought-tolerant capabilities. Water thoroughly when the soil is completely dry to the touch. Avoid overwatering, as this can lead to root rot. Reduce watering during fall and winter months when the plant enters dormancy.
Temperature and Humidity: The ideal temperature range for string of dolphins is between 40-80°F (4-27°C). It tolerates average household humidity levels.
Fertilizer: Fertilize lightly during the growing season (spring and summer) with a balanced liquid fertilizer or organic compost. Excessive fertilization can harm the plant.
Pruning and Propagation
Pruning: Regular pruning encourages bushier growth and prevents legginess. Cut back long vines and remove any bare or damaged stems in spring or summer. The pruned cuttings can be used for propagation.
Propagation: String of dolphins can be easily propagated from stem cuttings in water or soil. Take cuttings with at least 2-3 nodes and remove the leaves from the bottom node. Place the cuttings in a glass of water and change the water every few days until roots develop. You can also propagate cuttings directly in soil by laying them on top and keeping the soil moist.
Potting and Repotting
String of dolphins can tolerate being root-bound and does not require frequent repotting. However, every few years, repot the plant into a slightly larger pot with fresh soil and adequate drainage holes. Use a pot made of plastic or terra-cotta, which helps absorb excess moisture.
Common Pests and Diseases
Common houseplant pests such as aphids, mealybugs, scale, and spider mites can infest string of dolphins. Treat infestations promptly with insecticidal soap or neem oil. The plant is not prone to specific diseases, but root rot can occur due to overwatering. Ensure proper drainage and water only when necessary.
Blooming and Aftercare
String of dolphins blooms occasionally with small, white, cloud-like flowers that have a sweet fragrance. To encourage blooming, provide ample sunlight and water thoroughly when watering. After blooming, continue to care for the plant as usual.
Troubleshooting Common Issues
Shriveling Leaves at the Base: This issue can indicate underwatering or natural aging. Water deeply when the soil is dry and prune any leggy vines to encourage new growth.
