Dolphin plants, also known as Senecio peregrinus or string of dolphins, are a popular houseplant that has become increasingly trendy in recent years. This succulent plant features unique leaves that resemble miniature dolphins jumping out of the water, making it a favorite among plant lovers. However, when it comes to growing dolphin plants, many people wonder how much space they should leave between each plant. In this article, we will explore this question in-depth and provide some helpful tips for growing healthy and happy dolphin plants.

What Are Dolphin Plants?

Before we dive into the topic of plant spacing, let’s first take a closer look at what dolphin plants are and why they are so popular. Dolphin plants belong to the Senecio family and are native to South Africa. The plant’s unique leaves resemble miniature dolphins, with two leaves growing together to create the shape of a jumping dolphin.

Dolphin plants are relatively easy to care for and can thrive both indoors and outdoors. They require well-draining soil and should be watered only when the topsoil is dry. These plants also prefer bright, indirect sunlight and should be protected from direct sunlight as it can burn their delicate leaves.

How Much Space Should You Leave Between Each Dolphin Plant?

When it comes to spacing dolphin plants, there are a few things to consider. First and foremost, it’s important to note that dolphin plants can grow up to 6 inches tall and 12 inches wide. As such, you should leave enough space between each plant so that they have enough room to grow without becoming overcrowded.

A good rule of thumb is to leave at least 6-8 inches between each plant. This will allow the plants to grow and spread out without crowding each other. If you plan on growing your dolphin plants in hanging baskets, you can space them slightly closer together as they will not be competing for space on a flat surface.

It’s also important to consider the size of the container you plan on using. If you’re growing your dolphin plants in a small container, you may need to space them further apart to prevent overcrowding. On the other hand, if you’re using a larger container, you can space them slightly closer together.

Tips for Growing Healthy Dolphin Plants

Now that we’ve covered how much space to leave between each dolphin plant, let’s take a look at some tips for growing healthy and happy plants.

1. Provide Adequate Sunlight

Dolphin plants prefer bright, indirect sunlight. As such, it’s important to place them in a location where they will receive enough light without being exposed to direct sunlight. A sunny windowsill is an ideal location for dolphin plants.

2. Water Sparingly

Like most succulent plants, dolphin plants do not require frequent watering. It’s essential to allow the soil to dry out completely before watering again. Overwatering can lead to root rot and other harmful diseases.

3. Use Well-Draining Soil

Dolphin plants prefer well-draining soil that allows excess water to drain away quickly. You can use a cactus or succulent potting mix or create your own by mixing potting soil with sand.

4. Fertilize Sparingly

Dolphin plants do not require frequent fertilization. You can fertilize them once every two months during the growing season with a balanced fertilizer.

5. Prune as Needed

If your dolphin plant becomes too long or leggy, you can prune it back to encourage bushier growth. Use a clean pair of scissors or pruning shears and make clean cuts just above a leaf node.


How often should I water my dolphin plant?

Dolphin plants only need to be watered when the topsoil is dry. This can range from once a week to once every few weeks, depending on the humidity and temperature of your home.

Can I grow dolphin plants outside?

Yes, dolphin plants can be grown both indoors and outdoors. However, they prefer warm temperatures and should be protected from frost.

How do I propagate my dolphin plant?

Dolphin plants can be propagated by stem cuttings. Simply take a stem cutting with several leaves and place it in well-draining soil. Keep the soil moist until the cutting takes root.

Why are the leaves on my dolphin plant turning yellow?

Yellow leaves on a dolphin plant can be a sign of overwatering or underwatering. Make sure to allow the soil to dry out completely before watering again.

In conclusion, growing healthy and happy dolphin plants is relatively easy as long as you provide them with the right conditions. By spacing them properly, providing adequate sunlight, and watering sparingly, you can enjoy these unique and beautiful plants for years to come.
