Likely causes
Overwatering
Most likelyHow to tell: The stems look mushy near the soil line and the plant stops growing entirely. You might also notice a sour smell coming from the pot.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a container, ensure it has drainage holes and dump any water sitting in the saucer.
Poor Drainage
PossibleHow to tell: The soil stays wet for more than a week after watering. The roots will appear brown and slimy instead of firm and white.
What to do: Repot the plant into a container with drainage holes using a well draining potting mix. Trim away any black or mushy roots with clean scissors before replanting.

When to worry
If the entire stem base turns black and soft, the plant is likely too far gone to save. Minor yellowing of lower leaves is normal as the plant matures.
Stopping it coming back
Always use a pot with drainage and wait until the top inch of soil is dry before watering again. Ensure the soil is loose and airy to prevent water from pooling.
