Bunya pine (Araucaria bidwillii)
Also known as: False monkey puzzle, Bunya
The **Bunya Pine (Araucaria bidwillii)** is an evergreen conifer indigenous to the southeastern coastal regions of Australia. Although commonly referred to as a pine, it is not a true pine tree. This unique tree produces large, football-sized cones containing edible seeds known as bunya nuts. These seeds have long been a vital food source for indigenous Australians, enjoyed in various forms, including raw, cooked, processed, and fermented.

How to Water Bunya pine?
For the Araucaria bidwillii, the watering should be generous, around 1000 milliliters per session, enough to soak through the entire root system without leaving excess water standing in the pot. This ensures that the roots absorb the maximum amount of water without being waterlogged.

What Is the Ideal Temperature Range for Bunya pine?
The ideal temperature range for Araucaria bidwillii is between 60°F and 75°F. This range provides optimal conditions for growth by ensuring that the plant's physiological processes function efficiently. Temperatures in this range support healthy photosynthesis and nutrient absorption, leading to robust growth and vitality.
What Soil is Best for Bunya pine?
Bunya Pine requires soil that drains well to prevent waterlogging and root rot. Good drainage ensures the roots can breathe, promoting healthy growth and reducing the risk of diseases. To thrive, Araucaria bidwillii benefits from a nutrient-rich soil. This provides essential minerals and nutrients, fostering robust growth and a strong immune system against pests and diseases. Incorporating organic matter like compost improves soil texture and fertility. This enhances water retention and nutrient availability, supporting the plant's health and vigorous development.
How to Fertilize Bunya pine?
For Araucaria bidwillii, use a balanced fertilizer. Liquid fertilizers should be applied at half the recommended strength, while granules should be spread evenly around the root zone.
How to Prune Bunya pine?
Do not remove more than 20% of the tree's foliage at one time, as over-pruning can put stress on the tree and disrupt its growth pattern. Avoid pruning during the winter unless absolutely necessary to prevent stressing the plant; winter could expose the tree to damage due to colder temperatures. Due to the height that Araucaria bidwillii can reach, ensure the use of appropriate safety measures if ladders are needed. It’s better to hire professionals for high branches.

How to Propagate Bunya pine plant?
1
Collect mature seeds from the cones of Araucaria bidwillii in late winter. Ensure the seeds are fully developed and undamaged for a higher germination rate.
2
Plant the seeds in seed-starting trays filled with potting mix. Sow them at a depth twice their diameter, cover lightly with soil, and mist to keep them moist.
3
Maintain a warm and humid environment, ideally around 25°C, to encourage germination. Use a propagation mat or a clear plastic cover to retain moisture and warmth.
How to Repot Bunya pine plant?
1
Repotting should be considered when your Araucaria bidwillii shows signs of being root-bound, such as slowed growth, roots emerging from drainage holes, or if the soil retains moisture for an extended period. Spring and summer are ideal because the plant is actively growing, allowing it to recover faster.
2
Select a pot that is 2 inches wider in diameter than the current one, with good drainage. The pot should allow room for root expansion without overwhelming the plant. This balance helps prevent water from pooling at the roots, reducing the risk of rot.
3
Opt for a sandy loam that ensures excellent drainage. A soil mix containing peat, perlite, and sand is ideal, preventing compaction and ensuring that oxygen reaches the roots. This type of soil mimics their natural habitat, keeping the roots healthy and stimulated.
