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. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in.
Watering & feeding
Macadamia is regular, moderate watering. As an Australian native, feed it only with a low-phosphorus native fertiliser — the Proteaceae are especially phosphorus-sensitive. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
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
For a cohesive, low-care bed, pair Macadamia with other plants that enjoy the same regular, moderate watering and subtropical climate. Repeat it through a border to tie the planting together and give a sense of rhythm. It combines naturally with other Australian natives in a habitat or water-wise garden.
