Azalea Flower Indoor Plant. Flower buds may shrivel and turn brown if exposed to the hot, dry air of a heat vent. A leaves and flowers may fall off an azalea that has been exposed to draughts, watered erratically, or if the rootball dries out.
I wouldn't recommend misting because azalea is prone to fungus, which can kill the plant. In late spring when the plant’s flowers are fading, you should give your azalea a nutrition boost. As an added benefit, azalea shrubs are a hummingbird magnet.
The best time to plant azaleas is in late spring or early fall.
Plant enthusiasts have selectively bred azaleas for hundreds of years. The plant needs good light, such as morning direct sun and afternoon shade or bright indirect light all day. Since florist azalea plants are different than outdoor azalea plants, indoor azaleas rarely do well planted in your garden. Learn how to care for indoor azalea trees with this helpful guide!
