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.
Yellowing leaves and edema
Overwatering is the primary threat; excess water causes yellow leaves, soft stems, and corky edema lesions on leaf surfaces. Let the top layer of soil dry between waterings and ensure the pot has drainage holes.
Mealybugs and fungus gnats
Mealybugs cluster along nodes and under tiny leaves; treat with alcohol swabs or diluted neem oil. Fungus gnats breed in consistently wet topsoil — allowing the surface to dry between waterings breaks their life cycle.
Leaf shrivelling and vine dieback
Underwatering causes the small leaves to shrivel and individual stems to die back from the tips; fine trailing stems dry out faster than thicker species, especially in warm, dry indoor air.
