Check these first
- Check the temperature near the plant for cold drafts.
- Inspect the soil for signs of waterlogging or a sour smell.
- Look for pests like spider mites that might be weakening the plant.
Likely causes
Cold Drafts
PossibleHow to tell: Leaves may yellow or brown quickly before falling off the stem. This often happens if the plant is near an air conditioner or a drafty door.
What to do: Move your plant to a warmer spot where temperatures stay between 65 and 80 degrees Fahrenheit. Ensure it is at least 3 feet away from any direct source of cold air.
Root Rot
PossibleHow to tell: The base of the stems may turn mushy or black, and leaves will drop even if the soil is wet. This is caused by overwatering or poor drainage.
What to do: Remove the plant from its pot and trim away any black, slimy roots. Repot into fresh, well-draining soil and ensure the pot has adequate drainage holes.

When to worry
It is normal for a very old leaf at the base to yellow and drop occasionally. You should worry if multiple leaves are dropping at once or if the stems feel soft.
Stopping it coming back
Keep the plant in a stable environment and avoid letting the soil sit in standing water.
