Planting Your Gardenia in Zone 6
When planting your gardenia in zone 6, choose a location that offers the following:
- Full sun to partial shade: Gardenias prefer a location that receives at least 6 hours of sunlight per day, especially in the morning. However, they can also tolerate some shade, particularly in hotter climates.

- Mulching: Apply a layer of organic mulch around the base of your gardenia to help retain moisture and regulate soil temperature.
- Pruning: Prune your gardenia after flowering to encourage bushier growth and more blooms.
- Winter protection: In zone 6, it’s important to protect your gardenia from the harsh winter conditions. You can do this by covering the plant with burlap or a frost blanket, or by bringing it indoors to a cool, bright location.
