Likely causes
Inconsistent watering
Most likelyHow to tell: The soil is bone dry for too long or constantly soggy. The plant drops leaves to conserve energy when it cannot manage its water intake.
What to do: Water when the top inch of soil feels dry to the touch. Aim for a consistent schedule every 3 to 7 days depending on the heat.
Low light
PossibleHow to tell: The plant is stretching toward the window and losing older leaves near the base. It is not getting the full sun it needs to sustain its foliage.
What to do: Move the pot to a spot that gets at least 6 to 8 hours of direct sunlight daily. If you are indoors, a south facing window is usually the best choice.

When to worry
It is normal for a plant to drop a few leaves when you first bring it home or move it to a new spot. If the leaf drop continues for more than two weeks, you need to adjust your care.
Stopping it coming back
Maintain a steady watering routine and ensure the plant stays in a bright, sunny location. Avoid moving the plant around once it has settled in.
