Likely causes
Overwatering
Most likelyHow to tell: The soil feels soggy and the base of the stem may look mushy or discolored. You might notice a sour smell coming from the pot.
What to do: Stop watering immediately and allow the top 2 inches of soil to dry out completely. If the rot is severe, remove the plant from the pot, trim away black or mushy roots with sterilized shears, and repot in fresh, well draining soil.
Poor Drainage
Most likelyHow to tell: Water sits on the surface of the soil for a long time after watering. The pot lacks sufficient drainage holes at the bottom.
What to do: Repot the plant into a container with multiple drainage holes. Use a chunky potting mix that includes perlite or orchid bark to improve airflow around the roots.

When to worry
If the stem base is soft and mushy, the rot may have spread too far to save the plant. It is normal for a few roots to look dark if they have been in contact with wet soil for a short time.
Stopping it coming back
Always empty the saucer after watering so the plant never sits in standing water. Ensure your soil mix is light and airy.
