String of Dolphins is a unique cool trailing succulent. The leaves on this plant resemble dolphins and it’s so much fun to look at. Plus, this plant is easy to take care of and grows crazy fast.

String of Dolphins main care directions.

  1. Water. Water when the soil is dried out as these plants are drought-resistant. The dolphin shaped leaves store water for a long time. I water my String of Dolphins when the dolphin leaves look shriveled up.
  2. Light. Thrives in bright indirect sunlight like a south facing window or under artificial grow lights.
  3. Fertilizer. Feed a high quality fertilizer like Dyna-Gro or use a plant food like Liqui-Dirt.
  4. Humidity. No special humidity requirements. Thrives in regular household humidity.

Here’s what to know so String of Dolphins thrives in your home.


String of Dolphins thrives in bright sunlight. The best kind of sunlight typically comes from a south facing window which gets the hottest, most intense sunlight of the day.

The second best place for this plant would be near a west or east facing window, which gets sunlight but not as much as a south facing window. The lowest light setting would be a north facing window, which gets very little light.

This is also a houseplant you can place under plant grow lights like T5 Barrina lights. I use these plant grow lights in my home for many of my plants and I love them. I even have my String of Dolphins sitting under T5 Barrina grow lights. These lights are running on a 13 hour timer every day.


It’s easy to know when to water your String of Dolphins because the leaves will start to thin out and look shriveled up. The leaves usually look plump and full of water, so when they start to look less like this, give the plant a good drink.

This plant is drought-tolerant since it is a succulent, so you’ll probably only need to give this a good soaking once every 10+ days. You’ll likely water more in the summer months and less so in the winter months.

Check your plants soil either by using a moisture meter or sticking your index finger in about two inches deep. If the soil is dry, it’s time to give your plant a thorough watering.


String of Dolphins is a succulent that thrives in well-draining soil, not compact or dense soil. An easy recipe for well-draining soil would be 2 parts coco coir and 1 part perlite. You can make this mix even chunkier by using perlite size #4 or with orchid bark, which is super chunky.

My favorite houseplant soil at big box stores is Fox Farm Ocean Forest houseplant mix. This mix contains everything you need to grow healthy and happy plants in your home. I like to use this mix and make it even chunkier with orchid bark or perlite, but this isn’t a necessary step.


String of Dolphins live in temperatures between 55°F and 85°F.


Feeding plants fertilizer is essential because your plants are getting the nutrients it needs in your home. Plus, fertilizer helps promote healthy new growth on your plants creating even larger plants in your home.

I love using Dyna-Gro because it’s cheap and easy to use. This is how it works.

  • Maintenance: Mix ¼ – ½ tsp. per gallon of water with every watering.
  • Production: Mix 1 tsp. per gallon of water, once a week.
  • Monthly Feeding: Use 2 – 3 tsp. per gallon of water.

I also use Liqui-Dirt which is technically a plant food, not a fertilizer. This stuff literally lasts forever and I’ve barely made a dent in the package after using it for almost a year. Liqui-Dirt is a microbial, micro-fungi, and vitamin complex which revitalizes your soil or hydroponics system (yes you can use this for leca plants!).


String of Dolphins thrives in regular household humidity of 20%. If you give your plant more humidity, it won’t hurt at all.


String of Dolphins propagation is simple. Take a cutting that has a few nodes on the stem to increase your chances of propagation success. The nodes are where the roots will grow.

Then you stick these nodes under water or into soil. If there are any leaves submerged underwater, get rid of those leaves as they’ll rot underwater. Roots will develop in a few weeks and then you can move the plant to wherever you wish.
