Care
Sunlight
Choose a location in full sun, with at least 6 hours of daily light. This tree loves bright, well-ventilated spots. It tolerates sea spray and windy sites well.
Soil and drainage
Plant your Allocasuarina in well-drained, light, and rather poor soil. It adapts well to sandy and chalky soils. Avoid heavy, waterlogged soils at all costs, as they cause root rot.
Watering
Once established, this plant is very drought-resistant. Water regularly during the first two years after planting, then gradually reduce watering. No watering is needed in Mediterranean regions once the plant is well-rooted.
Pruning and structure
Pruning is generally not necessary. Simply remove dead wood or damaged branches at the end of winter. Respect its natural slender shape.
Nutrition
No fertilizer is required. This plant adapts to poor soils and captures atmospheric nitrogen through symbiotic root nodules. Excess fertilizer can weaken the plant.
Diseases and pests
Very resistant to diseases, it may suffer from fungal infections if there is stagnant moisture. Maintain excellent drainage to prevent any health issues.
Did you know?
Though not a true conifer, Allocasuarina verticillata is often called 'Australian pine' because of its thread-like, layered foliage that resembles that of pines. Its tiny leaves are actually flattened branches (phyllodes) that perform photosynthesis—a remarkable adaptation to Australia's arid environments.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
