Check these first
- Stick your finger an inch into the soil to check for moisture.
- Lift the pot to see if water is sitting in the drainage saucer.
- Smell the soil for a musty or sour scent.
Likely causes
Overwatering
Most likelyHow to tell: The soil feels constantly damp and the plant looks wilted or yellow. If you smell a sour odor coming from the pot, the roots are likely decaying.
What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If the plant does not recover, repot it into fresh, well-draining soil and trim away any black, mushy roots.
Poor drainage
PossibleHow to tell: Water sits in the saucer for hours after you water. The soil stays heavy and dense, preventing oxygen from reaching the roots.
What to do: Ensure your pot has drainage holes at the bottom. Add perlite or coarse sand to your potting mix to improve airflow and drainage.
When to worry
If the stems feel soft or mushy at the base, the rot may have spread too far. If the roots are mostly black and slimy, the plant may not be salvageable.
Stopping it coming back
Always empty the drainage saucer after watering and wait for the top inch of soil to dry before adding more water.

Questions people ask
- How often should I water my pepper plant?
- Water every 3 to 7 days, but only when the top inch of soil feels dry. Always check the soil rather than following a strict calendar.
- Can I save a plant with root rot?
- Yes, if you catch it early. Trim the dead roots, repot in fresh soil, and be very careful not to overwater while it recovers.
