String of Dolphins (Senecio peregrinus) is a charming succulent known for its distinctive dolphin-shaped leaves. Here’s a comprehensive guide to caring for your String of Dolphins:
1. Light
- Sunlight: String of Dolphins thrives in bright, indirect light. They can tolerate some direct sunlight, particularly in the morning or late afternoon, but avoid harsh midday sun which can scorch the leaves.
- Indoor Placement: Place the plant near a south or west-facing window. If natural light is insufficient, consider using a grow light.
2. Watering
- Frequency: Water sparingly. Allow the soil to dry out completely between waterings. Overwatering can lead to root rot, a common issue with succulents.
- Method: Water thoroughly until water drains out from the bottom of the pot. Avoid letting the plant sit in water. In winter, reduce watering frequency as the plant’s growth slows down.
3. Soil
- Type: Use a well-draining succulent or cactus mix. You can also create your own mix by combining potting soil with perlite or coarse sand to improve drainage.
4. Temperature and Humidity
- Temperature: String of Dolphins prefers temperatures between 65-80°F (18-27°C). They can tolerate cooler temperatures down to 40°F (4°C), but avoid frost.
- Humidity: These succulents do well in average household humidity. They don't require high humidity and can suffer in overly humid conditions.
5. Fertilizing
- Frequency: Fertilize sparingly. During the growing season (spring and summer), use a balanced, diluted succulent fertilizer once a month.
- Type: Use a fertilizer specifically formulated for succulents and cacti, diluted to half the recommended strength.
6. Potting and Repotting
- Pot Choice: use a pot with drainage holes to prevent waterlogging.
- Repotting: Repot every 2-3 years or when the plant outgrows its pot. Choose a pot that is slightly larger than the current one and refresh the soil to provide nutrients.
7. Pruning and Propagation
- Pruning: Prune to maintain the desired shape and encourage bushier growth. Trim back any leggy or unhealthy stems.
- Propagation: Propagate by stem cuttings. Allow the cut ends to dry and callous for a few days before placing them in well-draining soil. Water sparingly until new growth appears.
8. Pest and Disease Management
- Common Pests: Watch out for pests like aphids, mealybugs, and spider mites. Treat infestations with insecticidal soap or neem oil.
- Diseases: Root rot from overwatering is a common issue. Ensure proper watering habits and good drainage to prevent this.
9. Dormancy
- Winter Care: String of Dolphins goes dormant in the winter. During this time, reduce watering and stop fertilizing. Keep the plant in a cool, bright location.
Additional Tips
- Handling: Handle the plant gently to avoid breaking the delicate leaves and stems.
- Environment: Avoid placing the plant in drafty areas or near heat sources like radiators, as sudden temperature changes can stress the plant.
By following these care instructions, your String of Dolphins should thrive, providing you with its unique and whimsical foliage for years to come.
