Factors Affecting Gardenia Size

- Watering: Gardenias need consistent moisture, but they don’t like to be waterlogged. Water them deeply and regularly, especially during hot weather.
- Pruning: Pruning can help to control the size and shape of your gardenia. Prune after flowering to encourage new growth and more flowers.
