Peperomia Prostrata String Of Turtles Care and Plant Needs

Size and Growth

Prostrata is a miniature peperomia plant with tiny, fleshy, succulent leaves that are only one-fourth of an inch wide and resemble turtle shells.

Its small-spadix-like structure has creeping or trailing leaves and white veins.

String of Turtle succulent has a slow growth rate, taking about 3 to 5 years to reach its mature, full size.

The height of the plant is approximately 1″ inch to 4″ inches, and its width is approximately 4″ inches.

When potted, this vining plant may form a thick mat and cascade over the sides of the container.

Foliage and Flowering

Peperomia prostate has tiny dark green and blue variegated fleshy button leaves, which look like they are swollen with water.

Every tiny leaf on its trailing vine has intricate multi-colored patterns covering its surface—the colors become muted with age and eventually become bicolored by maturity, typically a darker green contrasted by light green.

They have a beautiful pattern of white veins, which range in color from maroon to dark blue to purple, on young new growth and turn silvery-white as the leaves age.

The String of Turtle flower is insignificant. If the plant does flower, it produces tiny cream flowers on long flower spikes with no scent.

String of Turtles Light Requirements and Temperature

Pepper prostrata grows well in bright, indirect light.

If the leaves are dark green, do not expose plants to too much direct sunlight, as it can harm them.

As a tropical plant, the prostrata plant thrives in high-humidity environments. However, household conditions are often enough to keep this plant happy enough.

These plants grow well as indoor plants under fluorescent lights.

South and eastern-facing windows are best suited for Peperomia prostrate.

This plant species loves humid weather and grows well in homes with normal humidity and if the air is not too dry.

However, for warmer weather, mist the leaves or place the plant in a gravel tray with water.

The turtle shell plant thrives in temperatures of 65° to 75° degrees Fahrenheit. Plants may start to wilt in temperatures lower than 50° degrees Fahrenheit.

Watering and Feeding

This little plant likes moist soil but does not like overwatering. They prefer evenly moist soil but can suffer from overwatering, so be wary of the other plants they share a container with if they are high-water users.  

Allow the top layer of the soil to completely dry before watering again.

Keep evenly moist but not constantly wet. Waterless frequently in winter months when the plant’s growth slows.

Do not overwater and make the soil waterlogged. Overwatered pepper prostrata become wilted or grow scab-like protuberances from their leaves.

Moreover, it’s important to maintain an average humidity level of 60%. You can do so by placing your turtle plant close to a humidifier.

Also, you can use neem oil mixed with water to wash the tops of the leaves, as this is where most of these pests reside. 

String of turtles care also involves regular feeding with diluted fertilizers during the growing season and less frequent watering in winter.

The plant can lose a few bottom leaves, but if the plant drops many leaves, it could be due to temperature or fertilizer issues.

Fertilize the plant with diluted fertilizers every other week during the growing season. Or apply a time-release fertilizer at the beginning of the growing season.

Feeding is not required from the fall to late winter seasons.

String of Turtles Soil and Transplanting

Peperomia prostrate requires a loose, rich, well-aerated, and well-drained potting mix. A good potting mix rich in peat, coco coir, and other organic matter should be used. 

A good way to mix up the soil is to use 2 parts peat and one part sand or perlite and to change it or the top layer once a year.

While some recommend a commercial cactus or succulent soil for Peperomia string of turtles, that isn’t necessarily the best.

Like succulent plants, the best soil for string of turtles is a fast-draining soil capable of retaining moisture. 

Since this plant is quite small, repotting to large containers is usually not required. They have a shallow root system.

When planting prostrate plant, be careful not to overpot as it could make the soil waterlogged. Shallow soils do not retain excess water.

Repot the plant in spring while changing the topsoil. However, only go up one pot size as these plants remain quite small.

Grooming and Maintenance

Pruning peperomia prostrata plant with special care.

To stop vine growth, prune out just the top of some of the stems.

Too much pruning can make the plant lose its lush, bushy appearance and make it look spindly.

It can also permanently damage plant growth.
