How to Care for the Plant

Water
The most crucial requirement for macadamia, especially in the sapling stage, is abundant water that drains well. Per the Macadamia Nut Grower’s Handbook published by the Queensland Government, a mature tree can use up to 350 liters, or about 92 gallons, of water per week in hot, dry weather.
Fertilizer
It is not necessary to fertilize macadamia at the time of planting. The California Rare Fruit Growers say you should wait about six months after planting outdoors, then apply a balanced fertilizer that contains 1% nitrogen or less, as is appropriate for a slow-growing plant.A fish emulsion or citrus mix is best, applied per package instructions, usually in fall and winter.
Sunlight
It cannot grow in the shade.

Soil
Macadamia has a “proteoid” root system comprised of compact root clusters that take up nutrients with great efficiency. You would be wise to have your soil tested by your local extension service to determine its acidity and nutrient content. Amend the soil as needed, to achieve a pH of roughly 5.5 to 6.5.
Temperature
It grows best in areas where annual daytime temperatures are within the range 10 - 26°c, but can tolerate 8 - 35°c
