Likely causes
Overwatering
Most likelyHow to tell: The leaves will wilt and turn mushy, and the soil will smell sour or swampy. You might see the base of the stem turning dark and soft.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a pot, ensure it has drainage holes and remove any standing water from the saucer.
Poor Drainage
Most likelyHow to tell: Water sits on the surface of the soil for a long time after you water. The plant looks stunted and unhappy despite your regular care.
What to do: Repot the plant into a container with plenty of drainage holes using a well draining potting mix. Add perlite to the soil to improve aeration and prevent future compaction.

When to worry
If the stem base is soft and mushy, the plant may be too far gone to save. It is normal for the plant to look slightly thirsty if the soil has dried out properly between waterings.
Stopping it coming back
Always check the soil moisture with your finger before watering. Use a light, airy soil mix that allows excess water to escape quickly.
