How to Grow Macadamia Nut

Location and Ideal Climate

The Macadamia nut grows well in subtropical and tropical climates, preferring temperatures between 20°C and 30°C. It is important to choose a sunny location that is sheltered from strong winds, as the plant is sensitive to temperature changes and frost.

Land and Irrigation

The ideal soil for Macadamia is well-drained, with a neutral or slightly acidic pH (6.0-6.5). The plant needs regular watering, especially during periods of drought or during the flowering and fruit development phase. Avoid waterlogging that could compromise the roots.

Practical tip: To improve drainage, you can add sand or gravel to the substrate and use organic mulch to maintain moisture and reduce weeds.

Fertilization and Nutrition of the Macadamia Nut

Recommended fertilizers

The Macadamia nut needs balanced nutrition to produce quality fruits. We recommend the use of:

• Entec : A slow-release granular fertilizer that provides stabilized nitrogen to improve vegetative growth without causing excessive foliage development.
• NPK Original Gold COMPO: ideal for complete nutrition thanks to its balance of nitrogen, phosphorus and potassium, with essential microelements.
• HAIFA Multi-K Agri: a water-soluble fertilizer rich in potassium, essential for the quality of the fruit and for improving the plant's resistance to stress.
• Cifo Ert 23 Plus : for a controlled supply of nitrogen during the initial growth phase and the

It is recommended to fertilize the plant in early spring and summer to ensure the right supply of nutrients during flowering and fruit formation.

Note: Avoid excess nitrogen that could stimulate excessive foliage growth to the detriment of fruit production.

Common Macadamia Nut Pathologies and Problems

Macadamia nut plants can be prone to various diseases and pest attacks. Here are the most common pathologies and recommended treatments:

• Leaf spot: Caused by fungi that cause brown spots on the leaves.  
• Aphids: small insects that suck the linfa of the plant, weakening it.  
• Anthracnose: A fungal disease that attacks fruits, causing black spots and premature fall.
