Macadamia is a tree in the Proteaceae family, native to Queensland and North Wallace, Australia. Macadamia was introduced by Mexico and the state of Michigan. It is an important product for export to Mexican stores.

Hawaii is the largest exporter of macadamia nuts. Macadamia nuts are the equivalent of hazelnuts and the most nutritious nuts in the world.

It is the first fruit native to Australia and the first macadamia tree was planted in 1880 by Charles Staff.  let us tell you how to grow your own rich Macadamia Nut tree?

Growth environment conditions:

Macadamia grows in subtropical rainforests. The required soil is light to loamy soil. Prefer well-drained soils. Can grow in acidic, neutral and alkaline soils.

It does not grow well in the shade and should benefit from plenty of sun. In terms of irrigation, it should be considered that moist soils are recommended for its optimal growth. It needs a long summer.

In the early stages of growth should have plenty of water. Needs at least 1250 mm of rainfall per year.

Therapeutic properties and applications:

Macadamia, like olives, contains a large amount of useful unsaturated fatty acids and is about 86%. Macadamia nuts are very energetic and contain natural oils, proteins, carbohydrates and fiber.

It also contains vitamins niacin, B1 and B2, essential elements such as calcium, phosphorus, potassium, sodium, selenium and iron. Macadamia oil is rich in unsaturated fatty acids that reduce the risk of heart attack. These fatty acids can lower blood cholesterol levels.

Its seeds are used for nuts and are also used cooked in foods. It has a pleasant taste and nutrients.

How to propagate the plant:

Ripe fruit seeds germinate well in warm greenhouses. Its germination temperature is 25 ° C.

Seed sowing can also be done in the spring. When they reach the right size, we separate them from the initial bed and transfer them to the main place.

If we plant it outdoors from the beginning, we should plant plants around it to protect it from cold and wind.

Necessary points in planting

The tree that you get from the treasury is important in the following aspects:

Plant pot and how the roots are placed in it, soil texture, leaves, between nodes, suitable base, tree shape.

The size of the pot in which the plant is placed is very important. If the pot is too small, the root growth inside the pot is limited, the upper root will be damaged. The tree may appear green in the greenhouse but has little chance of full growth in the garden because a weakened root system cannot provide enough water and nutrition for the grown tree.

Macadamia grows at altitudes of zero to 1,500 meters above sea level, but its yield decreases sharply at altitudes above 600 meters. At altitudes above 640 meters, the tree produces for a longer period of time. The ideal temperature for growing macadamia nuts is between 16 and 25 degrees Celsius. Although the plant survives below 3 degrees Celsius, it is not resistant to frost.

Macadamia grows in any type of soil, but the soil suitable for growing macadamia nuts should be well drained and have no hard layers up to one meter above the soil surface. Clay soils that do not have good drainage are not suitable for growing macadamia nuts.

Soil preparation

To prepare the soil, the soil should be loose and soft as deep as possible. Because if the soil at the bottom of the holes is dense and compacted, the roots of the plant will be limited.

Cultivation distance

Different macadamia cultivars have different forms in appearance. Some of them have a spreading growth and some of them have a vertical growth. Also, the planting distance for each cultivar varies from place to place, but in any case it should be noted that as soon as the competition for light absorption begins, the yield decreases. Therefore, dense cultivation on commercial levels is not recommended.

Trees that grow vertically are planted 3.5 meters apart in 7-meter-long drifts, and cultivars that grow broadly 10 meters apart are planted in rows 6 meters apart.

Mixed culture

Sometimes other crops are planted among the young macadamia nuts. Before planting certain crops among macadamia trees, three basic points should be considered:

Planting crops that can damage the macadamia tree or have an adverse effect on its growth should be avoided.

Tall trees that create crowds and overall shade for macadamia trees should not be planted.

No other plant should be planted among the fertile trees because at this stage macadamia trees need special care to ensure maximum growth and yield.

Decomposition of leaves

Sample macadamia leaves should be prepared during the months of October and November. Sampling time is very sensitive and important. Healthy leaves should be selected for sampling. When sampling for the first time from a private garden, a soil sample should be added along with the leaf sample. From then on, sending a soil sample to the laboratory once a year will suffice. It is important to pay attention to the results of soil and leaf samples when preparing breeding fertilizers. Only the leaves of healthy plants should be sampled. These leaves should not be sunburned, insect-infested, or show signs of deficiency or disease.

After planting, the young tree should not be fertilized for at least a year, so that it becomes completely strong and stable. Regular fertilization should be done when the tree is strong and begins to grow:

Fertilizer should not be mixed with soil. Also, manure should never come in contact with the stems of young trees. For this reason, fertilizer should be spread evenly at a distance of 20 cm from the stem to about 50 cm from the tree drain. Since the macadamia tree is very sensitive to root damage, a light irrigation is required after each fertilization. Because most soils are naturally deficient in zinc or not at all, this element must be provided to the plant every year. Thus, the use of the following fertilizers with the mentioned concentrations is recommended:

Zinc oxide at a concentration of 200 grams per 100 liters of water

Zinc nitrate at a concentration of 150 ml in 100 liters of water

Watering systems

In areas with sufficient rainfall, macadamia nuts are grown in the dry season, but if there is no rainfall at the place of planting macadamia nuts, the timing of irrigation and the amount of water that should be given to the tree is very important. Lack of water slows down the growth of the tree and also reduces the quality and quantity of dried fruits.
