Check these first

Check if the plant is getting 6 hours of direct sun.
Look for cold drafts near the plant.
Inspect the undersides of leaves for aphids.

Likely causes

Insufficient Light
Possible
How to tell: The plant looks stretched out or leggy, and the lower leaves turn yellow before falling off. The stems appear thin and weak.
What to do: Move the plant to a spot that receives full, direct sun for at least 6 hours a day. A south facing window is usually the best location.
Temperature Shock
Possible
How to tell: Leaves drop suddenly after a cold draft or a big shift in room temperature. The leaves may still look green when they fall.
What to do: Keep the plant in a stable environment away from drafty windows or doors. Ensure the temperature stays above 50 degrees Fahrenheit.
