Pocket Botanist
Check these first
- Stick your finger 3 centimeters into the soil to check for dampness.
- Smell the soil for a sour or rotten odor.
- Inspect the base of the stems for soft, discolored tissue.
Likely causes
Overwatering
Most likelyHow to tell: The soil feels constantly soggy and the stems near the base look soft or mushy.
What to do: Stop watering immediately and let the top 5 centimeters of soil dry out. If the plant does not recover in a few days, repot it into fresh, well draining soil and trim away any black, slimy roots.
Poor Drainage
PossibleHow to tell: Water sits in the saucer or the pot lacks drainage holes at the bottom.
What to do: Ensure your pot has holes to let excess water escape. Empty the saucer after every watering so the plant never sits in standing water.

When to worry
If the stems are turning brown and mushy at the base, the plant is in serious trouble. A single yellowing leaf at the bottom is normal as the plant ages.
Stopping it coming back
Only water when the top 3 centimeters of soil are dry and always use a pot with drainage holes.
