Likely causes
Overwatering
Most likelyHow to tell: The soil stays damp for weeks and the plant looks limp despite having wet roots. The base of the stem may feel soft or mushy.
What to do: Stop watering immediately and let the soil dry out completely. If the plant does not perk up, remove it from the pot and trim away any black, slimy roots before repotting in fresh, well-draining soil.
Poor drainage
PossibleHow to tell: Water pools at the bottom of the pot or the soil remains heavy and dense. The plant shows signs of stress even when you water sparingly.
What to do: Ensure your pot has large drainage holes at the bottom. Mix perlite or coarse sand into your potting soil to improve airflow and drainage.

When to worry
If the stem base feels soft or mushy to the touch, the rot may have already spread too far. This is a critical condition that requires immediate repotting.
Stopping it coming back
Always wait until the top half of the soil is bone dry before you add more water. Use a terracotta pot to help the soil dry out faster.

Questions people ask
- How often should I water my Jatropha?
- Water every 7 to 14 days, but only when the top half of the soil is dry. Never follow a strict calendar, as light and temperature change how fast the soil dries.
- Can I save a plant with root rot?
- Yes, if you catch it early. You must remove the dead roots and provide fresh, dry soil to give the plant a chance to recover.
