Peperomia Prostrata: Grow and Care for the String of Turtles Plant

The string of turtles (Peperomia prostrata) is an indoor plant with round turtle-like leaves. The plant is also known as turtle vine, jade necklace, or chain of turtles.

Peperomia prostrata is a semi-succulent with long, cascading stems. Its trailing nature makes the plant suitable for terrariums, hanging baskets, and planters.

How to Care for the String of Turtles Plant

Light Requirements

The string of turtles thrives in indirect sunlight. Direct exposure may scorch its leaves and cause lanky growth. The plant requires 2-3 hours of bright sunlight. A north or east-facing window is ideal.

Vining plants often grow on high ledges or in dark settings. Ensure the light reaches every part of the plant to optimize its growth.

Soil Mix and Composition

Peperomia Prostrata is a succulent that requires proper drainage to prevent root rot and pest infestations. The plant needs a rich, loamy organic mix with drainage amendments.

Mixing coco peat with compost, perlite, or coarse sand ensures proper drainage. Perlite aids in aeration and drainage. Avoid heavy soils that may retain too much water. The pH should be neutral or slightly acidic to enhance the availability of soil nutrients.

Potting & Transplanting

Over-potting the string of turtles causes the potting mix to take longer to dry out, leading to stunted growth. The succulent grows best when root-bound. The plant should thrive in a pot at most 6 inches in diameter.

The string of turtles plant is a slow-growing plant that doesn’t require frequent transplanting. Transplanting is, however, crucial if it overgrows the pot. When transplanting, use a larger container and well-draining soil for proper drainage.

Temperature and Humidity

The string of turtles thrives in temperatures between 65-85℉ (18-29℃). Avoid temperatures below 55℉ (13℃) since it’s a tropical plant that withers in cold temperatures.

It thrives in moderate to high humidity levels. Maintaining humidity in the 40%-60% range is ideal for most indoor plants. Average indoor humidity is acceptable, while extra humidity is beneficial during dry periods.

A humidifier with forced air heat is helpful in cold winter areas. If the air in your home is too dry, try placing a humidifier near your plant. You can also set the pot on a water tray to boost humidity levels.

Watering and Drainage

Since the string of turtles is succulent, it features thick leaves that store water. Succulents don’t need frequent watering.

Instead, they’re more susceptible to over-watering in humid conditions. Overwatering causes root rot, so it’s essential to maintain a well-draining potting mix. Drain excess water from the saucer to prevent the plant from sitting in water.

Use a container with enough drainage holes and allow the soil to dry between waterings. Watering frequency depends on the growing medium. Water the plant only when the top 2 inches of the soil are dry.

Pruning and Training

Pruning the string of turtles helps prevent tagged and leggy vines. It also maintains the plant’s vigor and fullness. If the plant is too long, trim and prune it back to propagate new growth.

Use scissors or pruning shears to trim dead, infected, and leggy vines. Pruning also helps control the size of trailing plants and encourages new growth. It ensures a healthy appearance and controls their growth.

How to Propagate the String of Turtles Plant

The string of turtles is propagated using leaf or stem cuttings. Taking the cuttings at the beginning of the spring season guarantees optimal growth. Here’s how to propagate your String of Turtles:

  1. Look for a mature and healthy stem on your peperomia prostrata plant. Choose a stem that doesn’t show signs of damage or disease.
  2. Make a clean cut below a leaf node using clean, sharp scissors or pruning shears. A leaf node is the point where a leaf attaches to the stem. Ensure the cutting is at least 3 inches long and has a few leaves on it.
  3. Remove the leaves from the lower one-third to one-half of the stem. You will insert this bare part of the stem into the propagation medium.
  4. Prepare a well-draining propagation mix using peat moss and perlite or vermiculite. Moisten the mix slightly before planting the cutting.
  5. Create a small hole in the mix with your finger or a pencil and gently insert the bare stem part into the hole. Press the mix around the stem to provide stability.

Pest and Disease Management

The string of turtles plant is resistant to pests and diseases but may be susceptible under certain conditions. Here are some common pests and diseases:


Mealybugs are small, cottony pests that infest the leaves and stems of your plant. To control them, you should use a cotton swab dipped in rubbing alcohol. You can also use insecticidal soap or neem oil spray to treat the infested areas.


Whiteflies are small, soft-bodied insects resembling moths. Adult whiteflies can fly, which makes them challenging to eliminate. Use a neem oil solution to kill its eggs. Using commercial pesticides may be necessary if the infestation keeps worsening.

Spider Mites

Spider mites cause webbing on the leaves and suck the plant’s sap. Regular misting with water helps deter spider mites. If infestation keeps occurring, use insecticidal soap or neem oil spray. Repeat the treatment every few days until the infestation is eradicated.

Troubleshooting Common Issues

Here are some issues that the string of turtles experiences and tips to address them:

Yellowing Leaves

Yellowing leaves suggest overwatering or underwatering, so check soil moisture levels and adjust the watering intervals. Ensure the plant isn’t sitting in water to avoid root rot.

Root Rot

Root rot is a fungal infection caused by overwatering or poor drainage. Remove affected plant parts and repot in fresh, well-draining soil to manage root rot. Use well-draining soil and allow the soil’s top inch to dry out between waterings.

Leggy Growth

Leggy growth occurs when the plant isn’t exposed to enough light. Place your string of turtles plant in a brighter location while avoiding direct sunlight. Pruning leggy stems and providing adequate light makes the plant grow more compact and bushier.

Brown, Crispy Leaf Tips

Brown and crispy leaf tips indicate low humidity or underwatering. Mist the plant using a humidifier to increase humidity around the plant. Also, water the plant, allowing the top inch of soil to dry out between waterings.

Stunted Growth

Lack of new growth indicates insufficient light or nutrients. Consider moving the plant to a brighter location. Leaf drop also occurs due to environmental changes, such as temperature fluctuations or drafts. Keep the plant in a stable environment with consistent temperatures.
