I live in Oklahoma where it has been very hot all summer. Record set for most over 100 degree days. Many days were over 105. My gardenia plant looks great. I've had it in a large pot for over 15 years. I changed the pot a few years ago. In winter I put it in a sunny area and in summer I place it on the patio step where it has thrived. I have about 50-60 buds on it and they look great but won't bloom and fall off after awhile. Is it too hot for the plant to flower?
