Style

The Gardenia seems to be adaptable to most bonsai styles, both formal and informal, such as upright, slanting, broom, and so on.

Locations and Positions

From spring to the end of summer, your tree can enjoy being kept outdoors in semi-shade When the temperatures drop below 15 degrees, relocate it indoors by a south-facing window

Watering

The Gardenia has similar necessities as Azaleas or Syzygium. Keep the soil moist, possibly with rainwater, and avoid long periods of dryness or soaking wet conditions.

Feeding

From growing season to autumn, feed your gardenia every two weeks with a liquid fertiliser for ericaceous plants (acidic-loving plants), and reduce it to once a month during the winter.

Pruning and Pinching

Wait for flowers as you would do with the Azaleas. Remove the flowers, and then you can start to shape by pinching back the new growth or attempting structural pruning.

Repotting and Soil

The Gardenia jasminoides can be repotted every two years or as soon its roots fill the pot in early spring. Use acidic soil, such as Kanuma or a soil mix suitable for ericaceous plants. Ensure that the mix you use creates a well-drained environment for the tree.

Wiring

By the end of the summer, the plant will still be quite flexible, and growth will slow down, making it the perfect time for wire application.
