Check these first
- Stick your finger 2 inches into the soil to check for dampness.
- Smell the soil for a musty or rotten odor.
- Lift the pot to see if water is trapped in the saucer.
Likely causes
Overwatering
Most likelyHow to tell: The leaves will turn yellow and droop, and the soil will smell sour or swampy.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the soil is waterlogged, repot the plant into fresh, well draining soil and trim away any mushy, black roots.
Poor drainage
PossibleHow to tell: Water sits in the saucer for days after watering, or the pot lacks drainage holes.
What to do: Ensure your pot has holes at the bottom. Empty the saucer 15 minutes after watering so the plant never sits in standing water.

When to worry
If the stems feel soft or mushy at the base, the rot may have spread too far to save the plant. Yellowing leaves are a warning sign that you must act now.
Stopping it coming back
Only water when the top inch of soil is dry, and always use a pot with drainage holes.
