Insufficient light leads to the elongation of stems, compromising their strength and overall plant structure. Click here to learn how much light succulents need.

Why my String of Dolphins grow leggy?

Insufficient light is the primary cause of legginess in String of Dolphins succulents. When these plants do not receive an adequate amount of light, they tend to elongate their stems in an attempt to reach out for more light, leading to the development of long stems and a reduction in the number of leaves.

How to deal with leggy/Stretched String of Dolphins?

To address legginess in your String of Dolphins, it is crucial to provide the plant with sufficient light. Position it in a well-lit area where it can receive several hours of indirect sunlight daily. If natural light is limited, consider supplementing it with artificial grow lights to ensure the plant receives the necessary light intensity. Click here how to care for succulents with grow light.


Promote compact and bushy growth by pruning your String of Dolphins. Trim back the long and leggy stems, making the cuts just above a leaf node. This pruning technique stimulates new growth and encourages the hanging succulent to fill out, resulting in a more desirable shape and structure.

What needs to do to prevent String of Dolphins from stretching out?

To prevent legginess in your String of Dolphins succulent, it is crucial to establish proper lighting conditions right from the beginning. Place the succulent plant in a well-lit area, avoiding locations with low light levels.

Additionally, regularly rotate your plant to promote even growth on all sides. This practice prevents the plant from leaning towards a single light source, helping maintain a more balanced and compact growth habit.

3. Dolphins succulent losing leaves


When caring for String of Dolphins, it is crucial to be mindful of the delicate nature of its leaves. There are several factors that contribute to their fragility, and having an understanding of these factors can assist you in providing optimal care for your plant.


Why do my String of Dolphins lose leaves?

Overwatering: When the soil retains excessive moisture, it can lead to root rot, compromising the overall health of the plant and increasing the fragility of its leaves.

5. How to Propagate String of Dolphins?


String of Dolphins can be a bit challenging to propagate, but there are a few different methods you can try. The most common propagation methods for String of Dolphins include stem cuttings and leaves.

Among these two methods, stem cuttings are generally considered the easiest and most reliable for propagating trailing succulents. This is because succulent stem cuttings have a higher chance of developing roots and growing into new plants compared to leaf propagation.

Steps by steps guide:

  • 1. Choose a vigorous stem from the original dolphins succulent, ensuring it has a few sets of leaves.
  • 2. Utilize a sterilized and sharp pair of scissors or pruners to perform the task, make a clean cut just below a leaf node.
  • 3. Leave the stem cuttings undisturbed for a few days until the severed end develops a hardened tissue layer.
  • 4. Once calloused, place the cutting in a well-draining potting mix for succulents, burying the bottom nodes and leaving the leaves exposed.
  • 5. Keep the soil lightly moist and provide indirect light. In a matter of weeks, the cutting will initiate root formation and commence its growth.

After you've successfully propagated String of Dolphins using stem cuttings, it's important to provide proper care for the newly rooted stem cuttings:

Place the stem cuttings in a well-draining pot with a suitable succulent or cactus potting mix. Position the pot in a location with bright, indirect light. Carefully water the stem cuttings in moderation, ensuring that the soil is allowed to fully dry between each watering to prevent any risk of rot. Gradually acclimate the new plants to longer durations of sunlight, as they may be sensitive to direct sunlight initially.

Once the stem cuttings have established roots and started growing, you can treat them like mature String of Dolphins plants, following the same care guidelines for watering, light, and temperature.

6. Is String of Dolphins Toxic to Cats or Dogs?


The String of Dolphins (Senecio peregrinus) plant can be toxic to pets if consumed. It contains compounds that can be harmful, particularly to cats and dogs. Ingesting the plant can lead to gastrointestinal issues such as vomiting, diarrhea, and abdominal discomfort. In more severe cases, it may result in symptoms like lethargy, loss of appetite, and even damage to organs.

To ensure the safety of your pets, it's crucial to keep the String of Dolphins plants out of their reach. Consider placing it in an area where they cannot access it, or choose non-toxic alternatives if you have concerns about their well-being.
