Though originally found in the Australian sub continents, the macadamia nut has grown to a viable cash crop in many parts of the world. Commercial macadamia nut farms are said to have been initially set up in Hawaii. Australians only began cultivating it commercially in the 1960s, during which time the crop was being spread across North America.
It is worth noting that the performance of these trees will depend on the temperature swings experienced in your orchard. Flowering will only take place if the temperatures dip below 19 degrees centigrade during the hours of darkness. Frosts and below freezing temperatures will certainly kill young trees or cause flower and leaf shedding in an established orchard.
The trees are classified as evergreen hardwoods, with an ability to compete with deciduous species in a plantation. The crop will do well in granite soils with good drainage and aeration to support their extensive root system and minimize decline and canker disease. Some agricultural officers also recommend the planting of windbreak trees to avoid breakage and uprooting of newly established plants.
The nut trees can grow to around ten feet in height with a very wide branch canopy. To avoid space contention issues with other activities, the holes must be made in grid formation at 30 meter intervals across the farm. Many people may lack the means to sample and test their soils in the recommended manner but an auger hole dug to the hardpan level may be filled with water to note the time it takes for it to drain off.
A large farm will have to be worked over with machinery, so stony zones or stretches of land with a high gradient must be avoided. Instead of doing site selection on your own, consider hiring a landscaper to help you with the task. Choosing the wrong site may make you unpopular with your neighbors or hamper access to the farm by machines.
As much as possible, rows should be restricted to the north south direction to maximize interception of sunlight on both sides of the rows. Also important is the selection of the appropriate plant species to cultivate on your farm. While neighboring farmers may offer valuable advice on this, recall that some individuals could give you unsubstantiated opinions.
Some processors also have restrictions on the varieties of nuts they are willing to process in their factories. Varieties should be blended during planting to encourage cross pollination as it improves kernel quality and the count of nuts. During harvesting, strive to sort out the various nut species to avoid contention with the processors.
Do not rush to plant any imaginable tree as a windbreak for your orchard. A major shortcoming with this practice is creating secondary hosts for pests that frustrate farmer efforts to improve production. In some cases, the yields from macadamia nut farms have declined simply because such trees are competing with the cash crop for the available growth resources. Windbreaks are not absolutely necessary after four years of macadamia growth as the stems have developed hardy tissue and an elaborate root system.
