Propagation of Queensland Nut:

Seed - best sown as soon as it is ripe in a warm greenhouse. The dehusked seed germinates quickly at 25C. The seed can also be sown in the spring in a warm greenhouse. 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.
