Pocket Botanist
Check these first
- Poke your finger into the top 2 inches of soil to check for dampness.
- Lift the plant out of its pot to inspect the roots for a slimy or brown appearance.
- Verify that your pot has drainage holes.
Likely causes
Overwatering
Most likelyHow to tell: The stems feel mushy at the base and the leaves turn yellow or black.
What to do: Stop watering immediately and let the soil dry out completely. If the soil stays wet for more than a few days, repot the plant into fresh, well draining potting mix.
Poor Drainage
PossibleHow to tell: Water pools at the bottom of the pot or the soil remains soggy for weeks.
What to do: Ensure your pot has drainage holes at the bottom. Use a cactus or succulent mix to provide better airflow to the roots.
When to worry
If the stems are mushy and falling over, the rot has likely reached the crown and the plant may not recover. It is normal for a few lower leaves to drop if the plant is adjusting to a new environment.
Stopping it coming back
Only water when the top 2 inches of soil are completely dry. Always empty the saucer after watering so the plant never sits in standing water.

Questions people ask
- Can I save a plant with root rot?
- Yes, if you catch it early. Trim away the mushy, black roots with clean scissors and repot the plant into dry, fresh soil.
- How often should I water my peperomia?
- Water every 7 to 14 days, but only when the top layer of soil feels dry. Never water on a strict schedule regardless of soil moisture.
