How to Care for a String of Dolphins?

The string of dolphins is an easy-to-care-for succulent that requires minimal maintenance. Its plump leaves retain water for a relatively long time, making it drought-tolerant and ideal for those who cannot keep up with a regular watering schedule.

Here is a quick overview of the essential factors to consider when caring for your string of dolphins:


The string of dolphins needs plenty of bright, indirect light. It thrives best in a location with direct morning sun and filtered afternoon sunlight. You may also want to set up a fan or misting system to help keep the air around the plant cool. Keep the succulent out of direct sunlight to avoid sunburn.

If you are growing your string of dolphins indoors, ensure that it is placed in an area with bright light but away from direct sunlight. Ideally, you should have it on a south-facing windowsill to benefit from the natural light.

If you live in an area that doesn’t receive plenty of natural sunlight, you may want to use artificial grow light to supplement the plant’s sunlight needs.

When and How to Water

The string of dolphins should be watered deeply and infrequently — about once a week or every two weeks. Over-watering can be an issue, so check the soil before watering again. During the winter months, you can reduce the watering frequency to once every two or three weeks.

The best time to water your string of dolphins is in the morning when temperatures are cooler and the leaves have had time to dry out overnight. Water deeply at the base of the plant, not directly on its leaves.

Over-watering can be an issue, so check the soil before watering again.

Ideally, aim for the hours between 6:00 am and 10:00 am. However, if you cannot water your plant during these hours, you can still water it late in the evening.

Use the bottom-up watering technique to avoid over-saturating the soil. Apply water slowly until it drains out of your container’s bottom and stop.

Temperature Requirements

The string of dolphins tends to thrive in temperatures ranging from 55-85°F (13-30°C). Keep in mind that the plant may go dormant during winter, so reduce watering and keep it away from cold drafts.

Note: Avoid temperatures below freezing, as this can cause damage to your string of dolphins.

Soil & Pot Requirements

The string of dolphins needs well-draining soil mixed with sand or grit for better aeration. A good potting mix would be a combination of one part potting soil and two parts peat moss or coconut coir.

Fortunately, you can purchase good quality potting mix from your local garden center or online. Put the soil in a shallow planter with drainage holes; your succulent should be good.


The string of dolphins does not need much fertilizer but may benefit from occasional fertilization during the growing season. If you opt to fertilize your succulent, use an all-purpose or balanced fertilizer and apply it once every two weeks.

Make sure you use a fertilizer specifically designed for succulents and cacti, as these are more likely to provide the right amount of nutrients your string of dolphins needs.

Never over-fertilize your succulent; excessive fertilizer can cause burn marks on the leaves and even kill the plant. Never fertilize your succulent in the winter months!

Pests & Diseases

The string of dolphins is relatively resistant to pests and diseases, so if you take good care of your plant, you should have few problems. Avoid overwatering or leaving water sitting in the pot for too long, as this can lead to root rot — a fungal disease that can cause severe damage to your succulent.

The string of dolphins can be pruned infrequently, but you may want to trim off dead or dying leaves now and then. If any leaves are damaged beyond repair, they should be removed immediately.

Also, if you notice some stems growing too long and becoming spindly, you can prune them back to encourage new growth. Pruning your succulent is essential for maintaining its shape and keeping it healthy.

Propagating the String of Dolphins

The string of dolphins can be propagated through stem cuttings. Take a stem cutting with at least two sets of leaves and leave it to dry for several days, then place the stem in well-draining soil.

Keep the soil moist but not soggy, and provide plenty of light. With patience and care, new plants should emerge from the stem cuttings within a few weeks.

The temperature is one of the most important things you need to pay close attention to when propagating the string of dolphins. Keep the propagation container away from cold drafts and avoid exposing it to temperatures below 55°F (13°C).

Does the String of Dolphin Bloom?

Typically, this succulent only produces a few flowers. Although it is possible for it to bloom, this is usually only possible when the plant is exposed to extreme temperatures (both hot and cold).

If you see any blooms, expect small yellow or white flowers with a six-petal star shape. Unfortunately, these flowers don’t last very long, so enjoy them while you can!

How Often Should I Repot My String of Dolphin?

This succulent is a relatively slow grower, so it will not need to be repotted often. Repot the string of dolphin when the roots become overcrowded and pot bound, which usually happens every one or two years.

Make sure you use a good quality potting mix and provide plenty of drainage holes. As with other succulents, take care not to overwater it.

The best time to repot your string of dolphins is in spring.

Typically, the new container should be slightly bigger than the old one, and make sure you don’t water your succulent until it has had a few days to adjust.

The best time to repot your string of dolphins is in spring. This will give the plant plenty of time to adjust and grow before cooler temperatures arrive in autumn.

Although it requires minimal care, the string of dolphins can be a tricky succulent to keep alive, especially when you repot it. Therefore, be sure to do everything correctly.


The string of dolphins is a unique and exciting succulent that is easy to care for as long as it gets plenty of light, water, and temperature.

With its trailing stems, this succulent makes an excellent choice for a hanging planter or a windowsill.

If you take good care of your string of dolphins, it can last for years and create a stunning display in any room.
