This guide covers when to plant Bunya Nut in your region, the position and soil it likes, how to plant it, day-to-day care, the pests and diseases to watch, and how to harvest and store your crop.
When to Plant in Your Region
Bunya Nut is a warm-season crop, fully frost-hardy. In subtropical South-East Queensland it is best planted in January, February and March. Timing shifts with your climate, so choose your region below for a local calendar.
Varieties to Try
Bunya Pine
Standard species. Massive tree. Produces cones after 15+ years. A serious long-term planting.
Try: Daleys, local council nurseries, native plant nurseries
Position and Soil
Give Bunya Nut full sun (at least 6 hours a day). It does best in free-draining soil with a pH around 5.5 to 7. Dig through plenty of compost before planting, and mulch to hold moisture and keep weeds down. It needs an open garden bed rather than a pot, getting too big or deep-rooted for containers.
Planting
Plant Bunya Nut into a well-prepared hole the same depth as the rootball and twice as wide. Allow about 1500 cm between plants (more for full-size trees) so each has room and airflow. Water in well, stake if needed, and keep the area weed-free while it establishes.
Araucaria bidwillii. Ancient Gondwanan conifer. Massive tree (30-50m), not for small gardens. Huge cones (up to 10kg) drop in January-March containing edible nuts. SAFETY: Stand clear of trees during cone drop. Culturally significant to First Nations peoples. Nuts are rich, starchy, and delicious roasted. Trees fruit in cycles (heavy crop every 3 years). Plant only if you have serious space.
Care
Water consistently, roughly 8 L per plant every 4 days in warm weather, less in cool or wet spells. Feed every few weeks through the growing season with a balanced organic fertiliser, and keep mulch topped up.
Pests and Diseases
Keep an eye out for Few. The main diseases to watch are Few. Good spacing, watering at the base rather than over the leaves, and crop rotation prevent most problems. See our Pest and Disease Guide to identify and fix any issue.
Harvesting and Storage
Bunya Nut is typically ready to harvest within roughly 182 months once established (young plants may take a season or two longer). Fresh nuts fridge for 2 weeks. Roasted and frozen for months. Dried flour stores well.
In the Kitchen
In the kitchen, bunya nut is good roasted in shell over coals, boiled and mashed, ground into flour for damper and baking and sliced and fried like chestnuts. Nutritionally: high in protein and complex carbohydrates and rich in zinc and magnesium.
