Growing Excellence,
Every Season

Producing world-class macadamias begins long before harvest. At Golden Macadamias, our growers follow a proven seasonal rhythm rooted in science, experience, and sustainability. From flower to final nut, every step of the journey is carefully planned and executed.


  • A Year in the Orchard

    Season Cycle

    The macadamia season follows a predictable cycle, with each phase requiring precise care to ensure tree health, nut quality, and maximum yield.

    Jun - Aug


  • Flower Initiation

    Flowering begins across orchards as growers focus on early pest scouting and irrigation management to promote strong flower development and prepare for the season ahead.

    Sep


  • Flower Formation

    Flowering intensifies with early nut formation beginning. Foliar nutrients and targeted insecticides protect developing blooms while fertiliser applications support successful nut set.

    Oct - Dec


  • Nut Development & Pest Control

    The peak growth period requires vigilant pest monitoring and consistent irrigation. Leaf and soil sampling guides nutrient management while targeted crop protection ensures healthy nut development.

    Our Integrated Pest Management (IPM) system is built on the latest research and hands-on support. Trained field teams regularly scout orchards, while growers receive practical training in safe chemical handling and calibration. Every step adheres to strict spray safety and audit requirements, keeping orchards protected and compliant.

    Dec - Jan


  • Crop Assessment

    Crop estimates and maturity sampling determine optimal harvest timing. Continued pest scouting and strategic late-season interventions maintain crop quality as harvest approaches.

    Apr - June


  • Harvest and Pruning

    Full harvest season with responsible ethapon application to support nut drop. Early cultivar pruning begins in May while irrigation is typically paused post-harvest.

    By improving light penetration and air circulation, pruning enhances spray efficiency, harvest access, and long-term orchard balance, ensuring trees remain healthy and productive year after year.



  • The Tree's Natural Rhythm

    Tree Life Cycle

    Understanding the macadamia tree’s biological phases helps guide informed decisions across the orchard season.

    Jun - Aug

  • Reproductive Transition

    The tree awakens from dormancy as internal flower buds develop and carbohydrate reserves peak. Increased root activity signals the shift into reproductive mode.

    Sep


  • Peak Flowering

    Full bloom and pollination mark the tree's reproductive peak. Energy focuses on nut set while minor vegetative growth provides balance to the flowering surge.

    Oct - Dec


  • Early Nut Development

    Shell and embryo development begin as the tree channels energy toward nut formation. Intermittent vegetative growth continues alongside the primary reproductive focus.

    Dec - Jan


  • Kernel Filling

    Kernel and oil accumulation intensify as nuts approach final size. The tree begins rebuilding carbohydrate reserves while maintaining focus on nut quality.

    Jan - Mar


  • Maturity Phase

    Husk split signals maturity as nut drop begins. A new root flush emerges while the tree gradually transitions from reproductive back to vegetative growth.

    Apr - June


  • Nut Drop and Dormancy

    The reproductive cycle concludes as harvest peaks. The tree enters metabolic rest while internal bud differentiation quietly begins the cycle anew.


De-husking, Drying & Storage
Protecting Quality Post-Harvest

Once harvested, nuts are de-husked on-farm to remove the green outer husk before being cleaned, sorted, and dried to the correct moisture levels. They are then stored securely until transported to Golden Macadamias' world-class factory. Growers receive continuous training to ensure each batch is handled with the highest standards.

Exploring the
Macadamia Cultivars

Macadamias were first discovered in Australia in 1857, but it was Hawaii that pioneered commercial farming. Inspired by Hawaii’s success, Australia and South Africa began cultivating macadamias in the mid-1900s. Today, South Africa is the world’s largest producer, with thriving orchards across Mpumalanga, Limpopo, and KwaZulu-Natal.

Macadamias are prized for their buttery crunch, rich nutrition, and versatility, used globally in snacking, baking, and gourmet foods. Behind every nut lies a unique cultivar, each with its own origin and characteristics:
