The String of Dolphins plant (Senecio peregrinus or Curio x peregrinus) is a popular succulent admired for its distinctive leaves that resemble leaping dolphins. Proper watering is paramount to maintaining its health and the plumpness of its foliage.
Understanding String of Dolphins Watering Needs
String of Dolphins is a succulent, adapted to store water in its specialized leaves and stems. This allows the plant to endure dry periods. Like many succulents, it is vulnerable to overwatering, a frequent cause of decline. Its ability to retain moisture means it requires infrequent, yet thorough, hydration.
When to Water Your String of Dolphins
Wait until the soil has completely dried out before watering your String of Dolphins. Assess soil moisture by inserting your finger one to two inches deep into the potting mix; if it feels dry, it’s time to water. Another method is to lift the pot and gauge its weight, as a dry pot feels lighter. The plant’s “dolphins” also offer visual cues, appearing dull, deflated, or less plump when thirsty.
Factors Affecting Watering Frequency
Several environmental and cultural elements influence how quickly your String of Dolphins’ soil dries, affecting its watering schedule. Increased light exposure, particularly direct sunlight, dries soil more rapidly; lower light conditions necessitate less frequent watering. Warmer temperatures and lower humidity accelerate water evaporation, while cooler temperatures and higher humidity slow this process.
The type and size of the pot also play a role. Terracotta pots absorb moisture and promote faster drying compared to plastic or glazed containers. Larger pots retain moisture longer than smaller ones.
Using a well-draining succulent or cactus mix allows water to pass through quickly, which is preferable to standard potting soil that holds more moisture. The plant’s seasonal growth cycle impacts its water needs, requiring more water during its active growing season (spring and summer) and less during dormancy (fall and winter).
Troubleshooting Watering Problems
Incorrect watering can lead to noticeable issues. Overwatering often manifests as yellowing, mushy, or translucent leaves, and the stem may feel soft or exhibit signs of rot. A foul smell from the soil can also indicate root rot, occurring when roots are deprived of oxygen due to excessive moisture. In contrast, underwatering typically results in wrinkled, shriveled, or flat leaves that feel dry and brittle, and leaves might even drop off. To address overwatering, allow the soil to dry completely and consider checking for root rot; for underwatering, provide a thorough soak.
Optimal Watering Techniques
When your String of Dolphins needs water, a thorough soaking method is recommended. Water the plant deeply until water freely drains from the bottom of the pot, ensuring the entire root ball is saturated. Drainage holes are essential to prevent water from pooling and causing root rot. After watering, do not allow the pot to sit in standing water for extended periods.
Bottom watering is another effective technique where the pot is placed in a shallow tray of water, allowing the soil to absorb moisture from the bottom up. This method ensures even saturation without wetting the foliage.
