Hi there, first time poster, hopefully this is the right place.

I have a gardenia plant (quite old I\'m guessing) that is on the lot of the house I bought a couple years ago. It seems some branches die(?) randomly. The first couple that died I cut in hopes it would help, but then others followed. So i\'ve left them alone. Some of the branches have leaves that turn yellow, with some browning on the edges. The rest of the plant seems happy and is actively budding. I\'ve regularly fertilized the plant with gardenia specific granular food. I don\'t know what else I should be doing.

I appreciate any advice you can provide!
Matt.
