Likely causes
Insufficient Light
Most likelyHow to tell: Leaves turn yellow or pale before falling off, especially those lower on the stem. The plant will look sparse and weak.
What to do: Move the plant to a spot that receives at least 6 to 8 hours of direct sunlight daily. If natural light is limited, use a high output grow light positioned 12 inches above the plant.
Temperature Shock
PossibleHow to tell: Leaves drop suddenly while still green. This often happens after a cold draft or a sudden shift in room temperature.
What to do: Keep the plant away from air conditioning vents or drafty windows. Maintain a steady room temperature between 70 to 85 degrees Fahrenheit.

When to worry
Worry if the plant loses more than a few leaves at once. It is normal for the oldest, lowest leaves to drop occasionally as the plant grows taller.
Stopping it coming back
Provide consistent, bright light and keep the environment stable. Avoid moving the plant to new locations once it has acclimated.
