The trees are not particularly self fertile and need insects like bees to pollinate them. Read rest of the answer. Plants can self-pollinate when they contain both male and female parts, allowing them to reproduce without pollen from another plant, whereas other kinds . Strong evidence for self-pollination is found, but no evidence that hand moving self-pollen within racemes, between raceme, or between trees improved final nut set, and it is shown that resource allocation probably overinflates measures of pollination deficit in macadamia. Self-unfruitful types, such as most apples, pears and sweet cherries, will need to . Initially they grow at much the same rate but once the dwarf trees get around 1.5m they begin to slow down and settle into maturity.
