Temperature and Climate

The String of Turtles is accustomed to a certain level of warmer temperatures, and anything higher or lower than that can damage the plant and affect its growth.

It likes average household temperatures of 65 to 75 degrees Fahrenheit (18 to 23 degrees Celsius).

It has average humidity requirements, so you do not have to spend much time misting the plant.


Light For Peperomia ProstrataPin

Light is essential for plant growth and strength. Therefore, understanding light levels is critical for caring for any Peperomia variety.

This plant is adaptable in terms of light settings. It can survive in medium-bright light with minimal direct sunlight.

But for better plant growth and to maintain the variegation, you should keep it under bright, indirect light.

If you are growing Peperomia Prostrata in a hanging basket or the planter is placed at a high spot, pay attention to the light available for the vines at the top.

Although the surrounding leaves will get light, the foliage in the middle will suffer from a lack of light.

Keep the String of Turtles away from direct sunlight to damage the green leaves.

If you do not have sufficient natural light in your house, you can use grow lights to help it thrive indoors.

The fleshy round leaves of this succulent, Peperomia will store water like most succulents, so you have to be cautious not to overwater.

Your plant should be watered regularly, but you should also allow the potting mix to dry a bit because of its succulent nature.

This will prevent root rot or other fungal infections caused by excess water on indoor plants.

If the succulent leaves look shriveled, it’s time to add water. A better approach is to rely on the soil condition for moisture levels in the mix.

Check the soil with your fingers. If the top inch or two is dry, you can continue watering; otherwise, wait for a day or two to let the soil dry.

Make sure there is a drainage hole for a perfect plant environment.

Soil and Fertilizer

Soil For Peperomia ProstrataPin

Plant the String of Turtles in an aerated and well-draining potting mix.

A simple Peromia mix is created using perlite, regular potting soil, peat moss, sphagnum moss, and a soil pH of 5-7.

Propagating Peperomia ProstrataPin

There are two standard techniques for propagating this semi-succulent plant. You can use the leaves or take stem cuttings from these vining plants.

Whatever method you use, have clean and germ-free tools for propagating String of Turtles.

You can take a 3-4 inch long stem cutting with at least one node or remove the leaves at the bottom for leaf nodes.

Once you bury the leaf nodes under soil or water, they will develop roots. You can also lay the cutting on the potting mix in a small pot.

For leaf cuttings, you can collect some leaves (with petioles) while pruning or repotting and bury these petioles in the soil.

Keep the soil moist and let the cuttings sit in bright, indirect light for necessary root growth within a few weeks.
