Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil remains damp for more than a few days after watering.
What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. Ensure your pot has drainage holes and empty the saucer after 15 minutes.
Root Rot
PossibleHow to tell: The plant looks wilted despite moist soil and the roots appear brown or slimy instead of firm and white. The base of the stems may also turn black.
What to do: Gently remove the plant from its pot to inspect the roots. Trim away any mushy, dark roots with clean scissors and repot into fresh, well draining potting mix.

When to worry
It is normal for a few older leaves at the base to turn yellow as the plant grows, but widespread yellowing across the plant is a sign of distress.
Stopping it coming back
Always allow the top inch of soil to dry out before adding more water, and never let the plant sit in standing water.
