Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow or mushy before falling off and the soil feels constantly wet. You might also notice a musty smell coming from the pot.
What to do: Stop watering immediately and let the top 3 inches of soil dry out completely. If the soil stays soggy for more than a few days, repot the plant into fresh, well draining soil.
Insufficient Light
PossibleHow to tell: The plant looks stretched out and thin, and leaves drop from the bottom up. It happens when the plant is moved to a spot with less than 6 hours of direct sun.
What to do: Move the plant to a location that receives full, direct sun for most of the day. Prune back any leggy stems to encourage the plant to grow back fuller.

When to worry
It is normal for a few older leaves at the base to drop as the plant grows. Worry if you see a sudden, heavy loss of leaves across the whole plant.
Stopping it coming back
Stick to a consistent watering schedule where you only water when the top few inches of soil are dry. Ensure your pot has excellent drainage holes.
