This is the macadamia for cooler regions, however the further south it's planted, the more sun it needs. The pointy, crinkled leaves are decorated in spring by long, graceful racemes of small flowers. These turn into strings of easily hulled nuts with a thin, pebbly shell. M. tetraphylla has a high sugar content and is considered the best flavoured nut for eating fresh. Nuts can also be easily roasted. Plant at 2m intervals to create a dense evergreen edible hedge.
Macadamias do best when given adequate summer irrigation and fertiliser. Suitable for screening, hedging or as a specimen tree, pruning is only required for shaping or to control growth. All Macadamias will produce an acceptable crop of nuts on their own, however, heavier cropping will occur if several trees are planted in the same area. Grafted trees will crop in 3-4 years. Seed grown plants in 7-8 years. Macadamia tetraphylla is the most cold tolerant variety, however they are still frost tender, especially when young. The further south they are planted, the more sun they require. Fertilise with Blood and Bone in spring and autumn. Water as required. Collect nuts from the ground in autumn and allow to dry. Shake the nuts - when you hear the rattle, they are ready to shell and consume.
