Macadamia integrifolia, commonly known as the smooth-shelled macadamia or Queensland nut, is a species of tree native to the rainforests of southeastern Queensland and northeastern New South Wales in Australia. It belongs to the family Proteaceae and is renowned for its delicious and nutritious nuts. The tree typically grows up to 15 meters (50 feet) tall and has glossy, dark green leaves. Its creamy white flowers bloom in clusters, followed by spherical fruits containing the prized macadamia nuts, encased in a hard shell. Macadamia integrifolia is valued not only for its culinary uses but also for its ornamental beauty, making it a popular choice for gardens in subtropical and tropical regions worldwide.

Cultivation:

1. Climate: Macadamia integrifolia thrives in subtropical to tropical climates with warm temperatures and high humidity. It prefers well-draining soil and is sensitive to frost, so it's best suited for regions with mild winters.

2. Sunlight: Plant macadamia trees in a location that receives full sun to partial shade. Adequate sunlight is essential for healthy growth and nut production.

3. Soil: Ensure the soil is rich in organic matter and well-draining. A slightly acidic to neutral pH level (around 5.5 to 6.5) is optimal for macadamia trees. Sandy loam or loamy soils are ideal.

4. Watering: Provide regular watering, especially during dry periods, to keep the soil consistently moist but not waterlogged. However, avoid overwatering as macadamia trees are susceptible to root rot.

5. Fertilization: Apply a balanced fertilizer specifically formulated for nut trees in early spring and again in late summer to promote healthy growth and fruit production.

6. Pruning: Prune macadamia trees to shape them and remove any dead, diseased, or overcrowded branches. Pruning should be done during the dormant season to avoid disrupting fruiting.

7. Pest and Disease Control: Keep an eye out for pests such as macadamia nut borers and diseases like phytophthora root rot. Implement appropriate pest management practices and maintain good sanitation in the orchard to minimize the risk of infestations and infections.

8. Harvesting: Macadamia nuts typically mature in late summer to early autumn. Harvest the nuts when the husks begin to split open and the nuts are fully developed. Remove the husks and allow the nuts to dry before storing or processing.

By following these cultivation tips, you can successfully grow and enjoy the delicious harvest of Macadamia integrifolia trees in your garden or orchard.
