If the soil gardenias are planted in is dry to the touch, water immediately to restore the plant’s vitality.Fertilize gardenias lightly in the spring once frost has passed with a well-balanced, extended-release, acid-forming, azalea fertilizer. Fertilize the shrubs again 6 weeks later to encourage extra flowers or faster growth of young shrubs. By well-balanced, this means to look for nutrients in the ratio of 2-1-1.In gardenias, the disease mainly affects young leaves & shoots, causing deformed leaves & buds, yellowing, & leaf drop. Treatment: Space plants properly to improve air circulation & reduce humidity, limiting fungal infections. Remove diseased tissue, dispose of fallen leaves, & add mulch.Location, Location, Location Gardenias perform best when they receive intense morning light and shade from the hot afternoon sun.
