Their botanical name is the Peperomia prostrata, but we know them best by their common name, the String of Turtles. You’ll also sometimes hear them called Magic Marmer.

Native to the tropical rainforests of Brazil, the string of turtles is a very unique variety of vining semi-succulent.

As their name implies, the string of turtles belongs to the genus Peperomia. Pereromia plants are identifiable by their fleshy, succulent leaves. These plants are actually categorized as a semi-succulent so they need a bit more water than your average succulent.

The String of Turtles gets its name from its appearance. The stringy, skinny vines of this plant are adorned with little round leaves that have a close resemblance to a turtle shell.

Sun & Light

String of turtles prefer a bright indirect light to grow in. Please avoid placing your plant in a location with direct sunlight, as too much light can cause severe damage to your plant’s foliage.

On the flip side, too little light can cause stunted growth. This plant thrives in about an hour or two of direct sun in the morning when the sun isn’t too harsh.

If you don’t have a spot where this plant can get enough sun you could always use a grow light! Again, be sure to not give it too much light, just enough to keep it healthy.


The string of turtle plant is a tropical plant this is native to the Brazilian rainforest, so they prefer a soil that is lightly moist. These plants are prone to overwatering, so it is important to maintain a certain level of soil moisture to keep your plants comfortable.

Soil Type

Despite being considered a semi-succulent, the string of turtles should not be planted in a soil that is marketed for succulents. Instead, string of turtles enjoys a soil rich in organic matter, namely peat moss.

For this reason, most seed-starting soils are perfect to use for the string of turtles. In addition, it is important to make sure this soil is slightly acidic and well-draining.


Including a regular fertilization routine to your plant’s care helps preserve the vibrant color and encourage vigorous growth in your plant.

During the growing season (spring and summer), treat your string of turtles to a diluted houseplant fertilizer. This should be done every two weeks. During the fall and winter months, completely cease fertilizing your plant.

Temperature & Humidity

The string of turtles differs from many other succulents in that they actually prefer average temperatures. Warm temperatures are fine for this plant since they’re tropical plants.

The ideal temperature range for this plant is between 68° and 75° F. However, they do not like super cold temps, so it is best to avoid placing them near a drafty window or air conditioning vent.

This plant also enjoys a more humid environment. They are tolerable of most household humidity levels, though in seasons where the weather might be drier, it is beneficial to introduce some type of humidity to its environment.

However, you don’t want a high humidity level as damp air isn’t the best for turtle strings. This can be achieved by placing an electric humidifier nearby or a pebble tray.


Pruning your Peperomia prostrata is necessary to help maintain bushy plant growth. Without pruning, your plant can become sparse and leggy in appearance. Prune your plant occasionally by removing any dead or damaged foliage; this will help encourage new growth.

You can also cut your plant down if you prefer your string of turtles to be a little shorter. Healthy plant cuttings can even be used to propagate new string of turtle plants.

Choosing a Pot & Repotting

The most important quality in a string of turtles’ pot should be drainage. Including ample drainage is essential to making sure your plant can properly expel excess water.

Without drainage holes in your pot, your plant’s roots can become waterlogged, which leads to fungal diseases such as root rot. You can also increase drainage by selecting porous pot materials such as unglazed ceramic or terra cotta.

The string of turtles prefers to be slightly root-bound, therefore they do not require frequent repotting and can do well in a small pot. It is recommended to repot when your plant become very root-bound (when roots begin growing out from openings in the plant pot).

They have a shallow root system so you won’t need to repot them very often! You’re most likely going to need to give them fresh soil rather than give them a larger pot.

When you do have to repot your plant, make sure to size up your pot size very gradually, only selecting a new pot that is a couple inches larger than the previous.
