Troubleshooting
String of Turtles problems — and how to fix them
String of Turtles (Peperomia prostrata) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Mushy, rotting stems and leaves
Overwatering and slow-draining soil are the prime cause; stems go soft and translucent from the base. Let the mix dry between waterings and pot in a chunky, free-draining medium.
Shrivelled, flattening leaves
Underwatering or very low humidity drains the moisture-storing leaves, leaving them thin and puckered. A thorough water and a brief humidity boost usually re-plumps them within a day or two.
Leggy stems with faded patterns
Too little light stretches the stems and washes out the tortoise-shell markings. Move it to bright, indirect light; trim leggy trails and replant the cuttings to thicken the plant.
Mealybugs and fungus gnats
White cottony mealybugs hide in leaf joints, while fungus gnats breed in chronically wet compost. Wipe pests off with diluted alcohol and let the soil surface dry to break the gnat cycle.
