Notes

Seed - raw or cooked. Sweet and delicious, they can be added to cakes, biscuits, ice cream etc[1][2]. They can also be ground into a flour and then added to cereals to enrich their protein value. The shell is very hard, making it difficult to extract the seed[3]. An edible oil is obtained from the seed[2].

Propagation

Seed - best sown as soon as it is ripe in a warm greenhouse[4]. The dehusked seed germinates quickly at 25°c[5]. The seed can also be sown in the spring in a warm greenhouse[4]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. If trying them outdoors, give the plants some protection from the cold for their first few winters. Cultivars may be grafted.

Cultivation

Plants grow best in rich moist soils and require copious summer watering in their early stages[1], though established plants are very drought resistant[5]. Trees require a sheltered position and are easily damaged by strong winds[5].

Plants can be grown in climates cooler than their native habitat, but they are not very hardy in Britain. They can survive slight frosts, however[5], and have succeeded outdoors in the Scilly Isles[6]. Growth is optimal between temperatures of 20 - 25°c, ceasing when they fall below 10°c or rise above 30°c[5]. Cold weather can result in the loss of the entire crop[5]. The macadamia nut is cultivated for its edible seed in many tropical and sub-tropical areas[1], there are some named varieties[1][2]. Plants are slow growing in cultivation, seedlings take 6 - 7 years to produce their first fruit[1]. The trees then produce commercial crops for about 40 - 50 years and can fruit for up to 100 years[5]. Pruning is not normally necessary, but is tolerated if carried out in the autumn[4].

This species was formerly considered to be a part of M. ternifolia[1].
