To overwinter indoors, avoid a drafty spot, give light but avoid direct sunlight, and keep the temperature in the range of nighttime low of 60 degrees and daytime high of 70 degrees. Then, add a saucer with gravel and water to help raise the humidity. For a more acidic soil, look for a fertilizer that is good for azaleas but avoid fertilizing in the winter months. I hope these tips help get your gardenia back to good health.
