String of Turtles

Peperomia prostrata

Vining & TrailingModerateSlow🐾 pet-safe

Good to know: Each dime-sized leaf carries its own turtle-shell mosaic, and the pattern is boldest on new growth. It's a Brazilian rainforest native, not a desert succulent, and that mix-up is a common and fatal one.

Through the year 🗓️

☀️ Summer now

Check moisture a little more often in heat, but let the top inch still dry between drinks.

🍂 Fall

Stop feeding, stretch watering intervals, and give it the brightest indirect spot you have.

❄️ Winter

Water sparingly. Cool, damp soil in low light is how most strings of turtles die.

🌱 Spring

Pin a few strands back onto the soil surface so they root and thicken the crown before the growing season.

The details

Light & placement

Light: Bright indirect; enough light keeps the turtle-shell pattern crisp, while harsh direct sun bleaches it
Ideal PPFD: 150–300 µmol·m⁻²·s⁻¹
Grow-light distance: 16–24 in below LED

Water & feed

Watering method: Water when the top 1–2 in dry. Semi-succulent leaves rot fast in constant moisture, but unlike a true succulent it shouldn't bake bone-dry for weeks. Bottom-watering keeps the delicate strands tidy.
Fertilizer: Balanced feed at ¼–½ strength, monthly in spring–summer. It burns easily.

Home & habit

Soil: Light, airy mix heavy on perlite (or a peat/perlite blend); pH 6.0–6.6
Humidity: Average to above (40–60%)
Temperature: 65–80 °F
Mature size: Strands trail 12 in; stays petite
Repotting: Rarely; tiny roots love a shallow, snug pot
Propagation: Strand cuttings pinned onto moist soil, or single leaves with a bit of stem; slow but reliable.

When something looks wrong

Overwatering signs: Mushy, translucent leaves that shed at a touch; blackened strands at the soil line
Underwatering signs: Flat, deflated, wrinkled leaves; brittle strands
Common pests: Fungus gnats, mealybugs, spider mites

Care notes: The killer is a deep pot of wet soil under a tiny root system, so keep it shallow, airy, and watered only when actually dry an inch down. Strands thinning at the crown usually means the top isn't getting light.

Common problems 🩺

The usual suspects when String of Turtles looks unhappy. Most houseplant trouble is watering or light, not disease — see all plant problems if you are not sure which plant is the culprit.

Turtle pattern fading

Likely cause
Not enough light — the markings need good light to develop.

What to do
Bright indirect light. New leaves come in patterned; old ones stay plain.

Mushy stems and shrivelling leaves

Likely cause
Overwatering. The fine roots rot quickly.

What to do
Let the top half of the pot dry out, and use a light, airy mix.

Sparse, stretched strands

Likely cause
Low light.

What to do
Move it brighter and trim to encourage denser growth.
