I want to grow my Gardenia in a pot, what is the proper soil mixture?
Any good potting mix will be ok. It can get a bit complicated to mix your own, but it is possible. I recommend just a standard all-purpose potting mix.
My gardenias is about 2 years old, it is planted in the ground. It bloomed the first year but has not bloomed since. It is growing very well, long new branches( they look wild)but no buds of flowers. I live in Fl, it get afternoon sun. Do I have to trim the long branches back?
You will want to remove spent blooms when they occur, and keep any unsightly branches trimmed. I would apply an all-purpose fertilizer just to help them out some. Here is an article that will help: https://www.gardeningknowhow.com/ornamental/flowers/gardenia/gardenia-plant.htm
My poor little gardenia bush is pathetic and has not changed in over 15 months. I have fed it and talked to it and I'm at my wits end.

I live in United Arab Emirates and I live in a central A/C appartment. In Feb 2017 I purchased 3 gardenia plants which have good flowers and kept near the windows. For 3 months the plant was good and I used to water them just to keep the soil moist. After 3 months the leaves became yellow and started falling and no flowers and now there are only twigs left. I need your kind advise as I am again planning to purchase this plant. I love this plant beyond anything. Thanks and Regards. Zia Tel: 00971508484720 e-mail: ziaaizzia@yahoo.com
This could have been a simple over-watering issue. It is best to let the top of the soil dry slightly between watering. Here is an article that will help: https://www.gardeningknowhow.com/ornamental/flowers/gardenia/growing-gardenias-indoors.htm
