Macadamia trees however, don’t like wet feet or windy locations.

Mature macadamia nut trees tolerate temperatures for brief periods only at – 4oC. They are often planted for their shady canopy, gorgeous pale flowers and, of course, their delicious buttery-flavoured nuts. Most cultivars are partly or completely self-incompatible so inter-planting with compatible cultivars is usually … The macadamia flowers are quite small so a small insect is required for pollination.

While most trees are self-pollinating, larger trees will benefit from having a partner tree to assist with pollination and nut development. The trees are not particularly self fertile and need insects like bees to pollinate them. The macadamia flowers are quite small so a small insect is required for pollination. They were used there for reforestation projects but were not satisfactory for this use. Although most of Australia's native bees are solitary, Trigona are quite social and form hives of about 10,000 bees. Preferred Climate Subtropical, Warm Temperate Learn About Climate Zones. Each flower has 20 ovules, four anthers attached to the petals, and a long stigma. Although propagation from seeds is easy, they are commercially not propagated from seeds because it takes up to 12 years to start producing nuts. Grown From Cutting Learn About Propagation Methods. If the tree is very large and you would like to reduce the size it can be pruned heavily. Macadamias will fall to the ground when they are mature so the best time to harvest the nuts is as soon as they drop.

Macadamia yields mainly benefited from the pollination service provided by butterflies rather than bees; butterflies were responsible for more than 50% of floral visits. These pollinators aided in ensuring fruiting success of inflorescences in the same magnitude as hand cross-pollination. The best time to prune is in May or June after harvesting the nuts, but it can be done at any time.
