- Smell the soil for any signs of decay.
Likely causes
Poor soil drainage
Most likelyHow to tell: The soil stays soggy for days after watering, and the leaves turn yellow before drooping. You might notice a sour or swampy smell coming from the base of the plant.
What to do: Improve drainage by amending the soil with organic matter or grit. If the plant is in a pot, ensure it has large drainage holes and never leave it sitting in a saucer of water.
Overwatering
PossibleHow to tell: The plant wilts even though the soil is wet, and the stems feel soft or mushy near the ground. The roots will look brown and slimy instead of firm and white.
What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If the rot is severe, you may need to dig up the plant and trim away the mushy roots.

When to worry
If the stems are turning black or mushy at the base, the rot is advanced and the plant may not recover. Mild wilting that improves after a day of drying out is usually fine.
Stopping it coming back
Always check the soil moisture before watering and ensure the plant is in well draining soil. Never let the plant sit in standing water.
