Check these first
- Stick your finger an inch into the soil to check for dampness.
- Smell the soil for any signs of rot or decay.
- Check if the pot has drainage holes at the bottom.
Likely causes
Overwatering
Most likelyHow to tell: The soil stays wet for a long time, and the plant looks wilted even though the dirt is damp. You might notice a sour or moldy smell coming from the pot.
What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If the plant does not perk up, gently remove it from the pot to inspect the roots for mushy, dark, or foul-smelling sections.
Poor Drainage
PossibleHow to tell: Water pools on the surface of the soil or takes more than a few minutes to drain through the pot. This keeps the roots constantly submerged in water.
What to do: Repot the plant into a container with better drainage holes using a well-draining potting mix. Trim away any dead or mushy roots with sterilized scissors before replanting.
