The String of Dolphins plant, a popular succulent known for its distinctive dolphin-shaped foliage, requires specific watering practices. Understanding its needs is crucial for its health and appearance, as proper watering prevents common issues and supports vigorous growth.
Understanding String of Dolphins’ Water Needs
The String of Dolphins is a succulent, storing water in its plump, dolphin-shaped leaves and stems. This adaptation allows it to endure drought and reduces its need for frequent watering compared to many houseplants. However, this also makes it highly susceptible to damage from excessive moisture. Overwatering is a significant risk, as consistently wet conditions quickly lead to root rot. Therefore, allowing the soil to dry out completely between waterings is crucial.
Key Indicators for Watering Your String of Dolphins
Determining when to water your String of Dolphins involves observing both the soil and the plant. The most reliable method is the “finger test”: insert your finger one to two inches deep into the potting mix. If it feels dry, it’s time to water. For succulents, it is best to allow the soil to dry out completely before rewatering. Another indicator is the pot’s weight; a dry pot feels noticeably lighter.
The plant’s appearance also provides visual cues. When it needs water, its plump leaves may look less full, feel softer, or show slight wrinkling. These changes indicate the plant is using its stored water. It is important to distinguish these signs from severe dehydration, which causes shriveled or crispy leaves.
Best Practices for Watering String of Dolphins
Once you determine your String of Dolphins needs water, apply it effectively. Use the “soak and dry” method: water thoroughly until it drains from the pot’s bottom holes, ensuring the entire root ball is hydrated. Proper drainage is essential; always use a pot with drainage holes and a well-draining soil mix, like a cactus or succulent blend.
After watering, empty any excess water from the saucer to prevent root rot. Both top-watering and bottom-watering are effective. Bottom-watering allows the plant to absorb water at its own pace, potentially encouraging stronger root development. Some gardeners use filtered water or rainwater to avoid mineral buildup.
Adjusting Watering for Environmental Factors and Seasons
Watering frequency for String of Dolphins should adjust based on environmental conditions and seasons. During active growing seasons (spring and summer), when the plant produces new growth, it requires more frequent watering, perhaps weekly. In cooler months (fall and winter), the plant enters dormancy, and water needs decrease, often to once a month.
Light exposure also influences frequency; plants in brighter light dry out faster. Higher temperatures and lower humidity increase soil evaporation, requiring more frequent watering. Pot type and size also matter. Smaller pots and porous materials like terracotta dry out faster than larger or plastic pots.
Troubleshooting Common Watering Issues
Incorrect watering can lead to common problems. Overwatering is indicated by yellowing, mushy leaves, or a soft, rotting stem. If these signs appear, stop watering and allow the soil to dry completely; severe cases may require repotting into fresh, dry soil.
Underwatering causes shriveled, crispy leaves or stunted growth. A thorough soak can revive an underwatered plant, then establish a consistent schedule. To prevent these issues, always check soil moisture before watering and ensure adequate drainage. Observing changes in leaf texture or color provides early warnings for timely adjustments.
