- Gently lift the plant to see if the roots are firm or mushy.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and droop even when the soil feels wet. If you pull the plant out, the roots will look brown, mushy, and smell bad.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the rot is severe, repot the plant into fresh, well draining soil after trimming away the dead roots.
Poor drainage
PossibleHow to tell: Water sits on the surface of the soil for a long time after watering. The pot may lack holes or the soil may be too dense.
What to do: Ensure your pot has drainage holes at the bottom. Mix perlite or coarse sand into your potting soil to improve aeration.

When to worry
If the stems are turning black at the base, the rot may have spread too far to save the plant. Yellowing leaves are a warning sign to adjust your watering now.
Stopping it coming back
Only water when the top inch of soil is dry and never let the pot sit in a saucer of standing water.
