Overwatering

Leaves yellow and then drop, and the soil stays wet for days after watering.

The fix

    Ease off watering, check drainage, and inspect for rot in the roots if it feels soft.

Underwatering

Leaves drop after the soil has been bone dry for a while.

How to tell

    Move it somewhere with stable, draft-free temperatures.

Too little light

It quietly sheds its lower and inner leaves over weeks while new growth stays small and pale.
