Commonly known as: String of Turtles
Botanical name: Peperomia prostrata
The String of Turtles (Peperomia prostrata) is a small trailing plant prized for its distinctive leaf pattern rather than size or speed of growth. Each leaf is round and marked with fine veining that gives it a shell-like appearance, creating texture and interest along delicate trailing stems.
Unlike many trailing plants, String of Turtles stays relatively compact and grows slowly. It doesn’t rush to fill space, which makes it ideal for shelves, small hanging pots, or areas where you want detail without visual clutter. Because the leaves store some moisture, this plant prefers a careful watering approach and reacts poorly to being kept constantly wet.
When grown in the right conditions — bright, indirect light and a free-draining mix — String of Turtles is a long-lived, rewarding plant that quietly does its thing without demanding attention.
String of Turtles Care Guide
Watering – How often should I water it?
Allow the soil to dry out almost completely between waterings. String of Turtles stores moisture in its leaves and is far more tolerant of dryness than excess water. Overwatering is the most common cause of failure.
Light – What light does a String of Turtles need?
Bright, indirect light is essential. Too little light causes the stems to stretch and the leaf pattern to fade, while direct sun can scorch the leaves. A position near a bright window with filtered light works best.
Humidity – Does it need extra humidity?
Average indoor humidity is sufficient. This plant does not require misting and prefers good airflow around the foliage.
Soil – What soil works best?
Use a very free-draining mix that doesn’t stay wet. Indoor Potting Soil works well as a base and can be improved with extra Perlite to increase drainage and airflow around the roots.
Feeding – How should I fertilise it?
Feed lightly during spring and summer using a diluted dose of Grobest Organic Fertiliser every 6–8 weeks. Avoid strong or frequent feeding, as this plant prefers lean conditions.
Repotting – Does it need regular repotting?
No. String of Turtles prefers to stay slightly root-bound. Repot only when the pot is clearly full, moving up one size at most. When repotting, retain some of the original soil around the roots and avoid disturbing them unnecessarily. If repotting, you may incorporate TerraPlus Natura N and Controlled Release Fertiliser into the fresh mix.
Pests – What pests should I watch for?
Generally pest-resistant, but mealybugs can occasionally appear along the stems. Inspect regularly and treat early with an insecticidal spray if needed.
Temperature – What temperature suits it best?
Best grown between 18 °C and 26 °C. Protect from cold drafts and avoid temperatures below 12 °C, which can cause leaf drop.
FAQ’s
Q: Is String of Turtles a succulent?
It’s often treated like one. While technically a Peperomia, it stores water in its leaves and prefers similar care.
Q: Why are the stems stretching?
This usually indicates insufficient light.
Q: Can it be grown in a hanging pot?
Yes, but it also works well on shelves where the stems can trail gently.
Q: Is it pet-safe?
Yes. Peperomia species are considered non-toxic to pets.
