Indoor Gardenia Care: Light, Humidity, and Temperature

Overview

Gardenias are fragrant, beautiful, but challenging. They need full bright sun, high humidity, and cool nights (55°F) / mild days (65°F) to mimic their native habitat.

Step 1: Maximum Light

Place in a south-facing window for strongest sun.

Step 2: Boost Humidity

Set pot on wet pebbles and run a humidifier nearby, especially in winter.

Step 3: Water When Top Inch Dries

Check soil frequently; water when the top inch feels dry.

Step 4: Acid Fertilizer

Use fertilizer for acid-loving plants (azalea type) April through November.

Step 5: Disease Management

Remove and destroy diseased leaves. Sterilize cutting tools with bleach. Apply fungicide if needed, following label directions.
