Likely causes
Excessive Watering
Most likelyHow to tell: The plant looks droopy and the stems near the soil line feel mushy or soft. You may also notice a sour smell coming from the pot.
What to do: Remove the plant from its pot and trim away any black, slimy roots with sterilized shears. Repot the plant into fresh, well-draining soil and a clean container.
Poor Drainage
Most likelyHow to tell: Water sits at the bottom of the pot or in the saucer for days. The roots suffocate because they cannot get enough oxygen.
What to do: Ensure your pot has large drainage holes at the bottom. Use a chunky potting mix that includes perlite to improve airflow around the roots.

When to worry
If the stem is mushy all the way up to the leaves, the plant may be too far gone to save. Act as soon as you notice the soil staying wet for more than two weeks.
Stopping it coming back
Always check the soil moisture before watering and never let the pot sit in a saucer of standing water.
