Why Your Gardenia Is Dropping Leaves: Light, Humidity, and Soil Requirements

Gardenia Needs Are Demanding

• Full sun all day.
• High humidity (hard in winter).
• Slightly moist, sandy soil—water lightly every 3 days so it only dries a little.
• Acidic soil and fertilizer.

Immediate Fixes

• Move to the sunniest window.
• Increase humidity: group with other plants, use a humidifier, or pebble tray.
• Check soil: repot into sandy mix if it’s heavy peat.
