Likely causes
Inconsistent Watering
Most likelyHow to tell: The soil feels bone dry or soggy, and the plant sheds both old and new leaves. You might notice the leaves turning yellow before they fall off.
What to do: Keep the soil consistently moist but not swampy. Water when the top inch of soil feels dry, usually every 3 to 7 days depending on your home temperature.
Temperature Fluctuations
Most likelyHow to tell: Leaves drop suddenly after the plant is placed near a drafty window, heater, or air conditioning vent. The plant looks otherwise healthy but is losing foliage rapidly.
What to do: Move the gardenia to a stable spot away from direct airflow. Keep the room temperature between 60 to 75 degrees Fahrenheit for the best results.

When to worry
It is normal for a gardenia to drop a few older leaves when adjusting to a new home. Worry if the leaf loss is rapid and affects the entire plant.
Stopping it coming back
Maintain a steady environment and consistent watering to keep your gardenia happy. Avoid moving the pot once it has settled into a spot it likes.
