Gardenias can be damaged by cold temperatures. So move potted gardenias

transferring garden gardenias into pots for the winter if your area
experiences freezing nights in the winter. Use a garage or greenhouse to
overwinter your gardenias. Do not disturb the plant or its leaves while
you're moving it; gardenias do not like to be disturbed or handled.
Fertilize your gardenias once a month, even in the winter. Put a layer
of fertilizer around the base of the plant.




I assume different gardenia types might respond to different conditions.
In my case, mentioned above, I never move the plant indoors on a cold
summer night. I saw gardenia bushes outside in Myrtle Beach, SC where
they sometimes get snow and frost.

My gardenia winters inside the house in the living room and I only
fertilize it sparsely twice a year.
