About Macadamia
Botanically, Macadamia integrifolia 'A4' is a moderate-growing fruiting tree in the Proteaceae family, native to Queensland and New South Wales. It reaches around 8 m tall and 6 m wide at maturity, with evergreen foliage. Cream green and white flowers appear in spring.
Where to grow Macadamia
Macadamia suits subtropical and warm-temperate climates and grows best in full sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot.
Soil & planting
Macadamia does best in free-draining and acidic soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Macadamia does best with regular, moderate watering. As an Australian native, feed it only with a low-phosphorus native fertiliser — the Proteaceae are especially phosphorus-sensitive. During the first growing season, water deeply whenever the upper soil begins to dry, then reduce the frequency as roots establish.
Pruning & care
Prune Macadamia after flowering to keep it compact and encourage the next flush of blooms. Overall it is low maintenance.
Using Macadamia in the garden
Macadamia earns its place for edible harvests, a feature or specimen planting and a shade tree.
Companion planting & design
Combine Macadamia with plants that share its preference for regular, moderate watering and subtropical climate. Use an odd-numbered group where space allows, or repeat it at intervals through a longer bed. It combines naturally with other Australian natives in a habitat or water-wise garden.
