The Q&A Archives: Gardenia's

Question: We've had a gardenia plant for 3 years now. The first year it had flowers, since then it has not produced flowers. We take good care of it and fertilize it and it has grown to 20 inches tall and it is full. Why does it not produce flowers anymore? Thank You

Answer: Growing healthy gardenia plants can be a challenge, even for seasoned gardeners. Some gardeners are lucky enough to live in mild winter climates and can plant them in the ground. In your cold winter climate, you must winter yours over indoors. Here are some hints for success: Gardenias require a rich, very acid soil (pH 4.5 to 5.0). An abundance of moisture and high humidity is the most important factor in successful gardenia culture. Unfortunately, gardenia is often a disappointment to gardeners because it can be very, very demanding. For flower buds to form and thrive, night temperatures need to be between 60-65F. During the day, temperatures should be 70-75F. A very constant, even temperature is required or buds will drop. Bright light is essential, but avoid direct mid-day sun in the summer. Best of luck with your gardenia!
