This succulent can also adapt to medium indirect light, making it versatile for different indoor environments.

Insufficient light can lead to flattened leaves, causing them to lose their distinguishing dolphin shape. Excessive light, especially direct sunlight, can cause sunburn, evident through brown, crispy patches on the leaves. Additionally, too much direct light can cause the plant to become leggy as it stretches toward the light source.

Artificial lighting can be an alternative if natural light is insufficient. Use full-spectrum grow lights to mimic natural sunlight. Positioning the plant about 12-18 inches from the light source will help maintain its original shape and vibrant color. This is particularly useful during winter months or in rooms with limited natural light.

Watering String of Dolphins

String of Dolphins requires a bit more frequent watering compared to many other succulents. Proper watering is crucial to prevent dehydration and overwatering issues.

The recommended method for watering is the “Drench and Drain” technique. This involves soaking the soil thoroughly until water drains out from the bottom of the pot, ensuring that the roots are fully watered.

Afterward, allow the soil to dry out completely before the next watering. This method mimics the plant’s natural habitat, where it would receive periods of heavy rain followed by dry spells.

Hydration can be checked using the “squish test.” Gently squeeze the leaves between your fingers. If the leaves feel firm, the plant is well-hydrated. If they feel slightly squishy, it’s time to water.

Brown and squishy leaves typically indicate overwatering and potential root rot, requiring immediate action to save the plant.

Common watering issues include overwatering and underwatering. Overwatering leads to root rot and is indicated by soft, brown leaves. On the other hand, underwatering can cause the leaves to shrivel and become dry.

To combat these issues, stick to the “Drench and Drain” method and ensure the soil has completely dried out before watering again.

Watering String of Dolphins correctly involves monitoring both soil moisture and leaf firmness. Employing these techniques will help maintain its healthy growth and distinctive dolphin-like foliage.
