The String of Turtles plant, scientifically known as Peperomia prostrata, is a delightful tropical native that can fit into even the smallest spaces. Not only is it a non-demanding houseplant that is perfect for both beginner gardeners and experts, but it is also non-toxic, making it safe to have in homes with pets and children.
What Makes String of Turtles Unique?
String of Turtles is native to the steamy tropical rainforests of Ecuador and Brazil, where it has been grown as a houseplant since the late 1800s. This plant is prized for its tiny leaves that resemble miniature turtle shells, densely spaced along delicate trailing stems.
Growing String of Turtles is easy because it has very few requirements to stay healthy and thriving. Moreover, this plant can contribute to your well-being as its foliage filters contaminants like formaldehyde from the indoor environment.
String of Turtles Care
String of Turtles originated in the rainforests of South America, so it thrives in hot and humid conditions. To provide the best care for your Peperomia prostrata, try to replicate those conditions as closely as possible.
Light
String of Turtles prefers bright but indirect light, as it grows in the shade of tree canopies in tropical rainforests. Aim for between 10,000 to 20,000 lux of indirect light for this plant to thrive. If you place it on a high shelf, consider using a grow light to provide the necessary light. Avoid exposing it to direct sunlight, as this can damage its delicate leaves.
Watering
Although String of Turtles is a semi-succulent that stores water in its leaves and stems, it still requires regular watering. Water the plant whenever the top 2 inches of soil have dried out. The goal is to maintain consistently moist, but not saturated, soil. On average, this may mean watering every 2 to 3 weeks. Ensure that water drains well through the pot’s drainage holes when watering.
Temperature
String of Turtles can adapt to the temperature range found in most homes. Keep it in an environment with temperatures between 65 to 85ºF (18 to 29ºC). Protect it from drafts and cold temperatures below 50ºF (10ºC). Avoid placing it too close to windows during extremely cold winter weather. If you choose to bring it outdoors during the summer, make sure to bring it back indoors before freezing temperatures arrive.
Humidity
Peperomia prostrata thrives in high humidity, ideally around 90%. However, it can still grow well in a humidity level between 40 to 50%. You can mist the plant regularly using distilled water or keep it in a terrarium to increase humidity. Grouping plants together also creates a moister microclimate. Consider using a small humidifier if you want to provide additional moisture.
Soil
String of Turtles requires well-draining soil to prevent waterlogging, as it cannot tolerate sitting in wet soil. Aim for a soil pH between 5 to 7, which is slightly acidic to neutral. You can create your own soil mix by combining peat moss or coconut coir with well-rotted compost or worm castings. Another option is to mix peat moss with perlite in a 2:1 ratio or use a mix of potting soil and perlite in equal parts.
Fertilizer
To encourage lush foliage growth, it’s recommended to use a fertilizer for Peperomia prostrata. A cactus fertilizer with a ratio of 0.5-1-1 or a standard 10-10-10 liquid fertilizer (diluted to half strength) works well. Apply the fertilizer after watering, ensuring even distribution to the roots. Fertilize every two weeks in spring and summer, and stop during the plant’s dormant period in fall and winter.
Potting and Repotting
String of Turtles grows slowly and only requires repotting every 2 to 3 years. Repotting may be necessary to refresh the soil, even if the plant hasn’t significantly increased in size. When repotting, increase the pot size only if the roots are crowded, but don’t choose a pot that is more than 2 inches wider. An unglazed clay pot with good drainage holes is recommended to prevent water retention.
Pruning
Pruning String of Turtles helps maintain its shape and prevent the stems from becoming too leggy. Remove any dead or damaged leaves, as they can attract pests or harbor diseases. When pruning, cut just below a node to encourage branching and increase the plant’s bushiness. Always use sharp, sterilized scissors to avoid damaging the plant.
Propagation
String of Turtles is easy to propagate, making it suitable for beginners. The most reliable method is rooting cuttings directly in soil. Take 3 to 5 inch sections of stems with leaves attached and lay them on the surface of damp potting soil or sphagnum moss. Press them down so that the leaf nodes have good contact with the soil. Cover the tray with plastic wrap, misting it once a week. Within a month, roots should form at each node, allowing you to separate the new baby plants.
Common Problems of String of Turtles
While String of Turtles is generally easy to care for, a few problems may arise. These issues can usually be prevented by providing the proper growing conditions and attentive care. If you notice any leaf discoloration or other signs of distress, it’s important to investigate and resolve the issue promptly.
Pests
String of Turtles is generally resistant to pests when kept healthy. However, if pests do appear, they can be easily dealt with. Spider mites may leave yellow bumps or webs on the leaves. Washing the plant’s leaves under running water can remove them. Whiteflies and mealybugs can be controlled by using insecticidal soap or wiping them off with a cotton ball dipped in rubbing alcohol.
Diseases
String of Turtles is not prone to many diseases, but it can be susceptible to fungal and bacterial infections if exposed to overly wet conditions. Avoid overwatering the soil and prevent water from getting on the leaves to reduce the risk of these infections. If root rot is suspected, check the roots for blackened sections with a bad smell. Remove any affected parts, replace the soil, and disinfect the pot to prevent re-infection.
Growing Problems
Sometimes, growing problems can occur even without diseases or pests. If your String of Turtles leaves turn red, it may be receiving too much direct sunlight. Move it to a location with less direct sunlight. Conversely, if the variegation on the leaves fades or disappears, it may not be receiving enough light. Dry stem tips or dropping leaves are signs of under-watering, so make sure to thoroughly soak the soil when watering.
Toxicity of String of Turtles
Peperomia prostrata is non-toxic to humans, pets, and children. You can safely grow String of Turtles in a home shared with cats, dogs, and rabbits. However, it is still recommended to keep the plant out of their reach to prevent any potential issues. Although it is not poisonous, cats and dogs may experience gastrointestinal issues if they consume large amounts of plant material. Additionally, cats can be rough with plants, so it’s best to keep them away from easy-to-reach areas.
String of Turtles Appearance
The String of Turtles plant has a charming appearance that can be either long and dangling or short and bushy, depending on your preferences and pruning. Its small, round leaves are variegated with markings that resemble turtle shells, creating a lush and tropical look. If light passes through the foliage, it can create a luminous effect.
Suggested Uses for String of Turtles
String of Turtles is a versatile plant that can be placed in various locations around your home or office. It thrives in bathrooms with diffused but bright light, adding greenery and benefiting from the humidity. Hanging baskets or potted plants on shelves or table edges are also great options.
