|I am a novice gardener and planted a gardenia that now has several brown blooms. When I first planted it and watered it, the blooms were white.
What could I have done wrong and how can I fix it?
|Growing healthy gardenia plants can be a challenge, even for seasoned gardeners. You're lucky, though, because your mild weather makes it possible to grow gardenia's outdoors. Many gardeners must winter them over indoors.
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!
