Question: despite spraying for thrips, leaves still falling off and no buds

Answer: 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. Morning sun is important but try to avoid direct mid-day sun in the summer. Keep the soil moist at all times except winter when watering should be reduced. Mist the leaves frequently, and feed with an acidified fertilizer such as one formulated for camellias or azaleas. Good luck with your gardenia!
