Plant Cultivation |
| Medium to large sized tree, generally to 30-40ft but occasionally taller.
Macadamia's grow best in tropical and subtropical climates. The trees
are reasonably hardy and can survive to 24F. In California, fruiting specimens
are found as far north as the San Francisco Bay Area, (trees are found
on the U.C. Berkeley campus, as well as the Strybing Arboretum in Golden
Gate Park.) Younger trees can be killed by freezes. Trees grow best in
full sun, except in hot climates where part shade is beneficial. Trees
like year-round water, and although they will stand periods of drought,
fruit set is usually lower. Propagation: By seeds or grafts. |
