I’ve been told you can prune gardenias all the way to the ground. Can this be done?

Question

My bush has not done well for several years and I was hoping to give it a new start.

Answer 1

I wouldn't cut it back, completely! I would only remove 1/3 of the plant at a time. This article will give you more information on when, and how to prune them properly: https://www.gardeningknowhow.com/ornamental/flowers/gardenia/when-to-prune-a-gardenia.htm
