Likely causes
Overwatering
Most likelyHow to tell: The base of the plant feels mushy or soft, and the leaves may start to yellow or collapse.
What to do: Stop watering immediately. Allow the soil to dry out completely for 30 days. If the rot is severe, you may need to repot the plant into fresh, well draining cactus mix.
Poor Drainage
PossibleHow to tell: Water sits in the saucer or the soil stays damp for more than a few days.
What to do: Ensure your pot has large drainage holes at the bottom. Use a gritty, sandy soil mix specifically for succulents to prevent water from pooling around the roots.

When to worry
If the center of the plant is soft or smells foul, the rot has likely reached the core and the plant may not recover.
Stopping it coming back
Always wait until the soil is bone dry before watering, and never let the plant sit in standing water.
