Growing Gardenias - Knowledgebase Question

Question by Zachkita

I would like to plant a gardenia in my yard, but know nothing about them. Have tried twice in the past but they both died. What kind of gardenia should I plant that will survive here? Should the plant get full or partial sun? I would like it to bloom but that is not the most important part of the plant living and doing well.

The most common gardenia is the G. jasminoides or cape jasmine. It will grow in your zone 8 garden, given the proper care.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!
