The Araucaria cunninghamii is an indoor bonsai and can only be kept outside in warm temperatures. Place your bonsai in a bright spot (south-facing window) with full sunlight. It thrives in warm climates around 15 °C – 27 °C. Choose a cool room away from direct heat sources like central heating.
There’s no fixed watering schedule—requirements depend on pot size, climate, soil type, and airflow. Water your Hoop Pine thoroughly as soon as the top layer of the soil is dry. Check daily to see if the top 25% is dry. Be consistent, but be careful not to overwater. When temperatures are below 5C, water less frequently.
Feed fortnightly or every month from March to October using Chrysal Liquid Bonsai Feed. We would recommend the Chrysal Liquid Bonsai Feed.
Pruning your bonsai is important not only to create or maintain an aesthetic style but also to ensure optimal health. Maintenance pruning can take place during the growing season. New shoots can be shortened to one or two leaves on mature trees. Don’t hard prune, Araucaria’s don’t back bud well.
If wiring Hoop Pine, take care as the branches break quite easily. We recommend using wires with a thickness that matches the thickness of the branch: if the wire you choose is too thick, you will damage the bark. If it is too thin, it won’t be effective.
Repotting your tree is an important way to provide a fresh and suitable soil mix and ensure appropriate root health. Every two to three years, repot your Hoop Pine bonsai at the start of Spring. Older trees respond well to a healthier proportion of Akadama in the soil mix. Older trees require repotting less frequently. This is a responsive species to root pruning.
Trees that are ready for repotting will require root pruning, a suitable new pot and appropriate soil mix.
When repotting, do not cut back the root mass by a large amount, and choose a well-draining soil mix that has a neutral or slightly higher PH value of 5-6, but not over 7. We tend to use a mixture of different speciality bonsai soils on our trees. Every species is different, so please contact us for free soil-mix advice or to take advantage of our repotting service.

Hoop Pine bonsai can be propagated through seeds, cuttings, or layering. Seed propagation should be done in the Spring when seeds are sown in well-draining soil and kept moist. Cuttings, taken from mature and healthy branches, are best done in the Spring or early Summer; use semi-hardwood material, dip the cuttings in rooting hormone, and plant in a well-draining soil mix, keeping them moist until roots develop. Air layering is also possible by wounding a section of the branch, wrapping it with moist sphagnum moss, and allowing roots to form before separating the new plant from the parent.
Hoop Pine bonsai can attract common pests such as scale insects, spider mites, aphids, and mealybugs. These pests feed on the sap of the tree and may cause yellowing, leaf drop, or stunted growth. Fungal diseases like powdery mildew, leaf spot, and root rot can also affect Hoop Pine bonsai, especially if the soil is poorly drained or the plant is overwatered.
This is dependent on climate and growing conditions. Hoop Pine bonsai is a subtropical species that prefers mild, frost-free environments. In the UK, it is frost tender and may struggle with cold winters. It is best kept outdoors in a sheltered, sunny spot during the growing season, but should be brought indoors or protected during frosts.
