Juglans australis wood is dense (640 kg/m), hard, and strong. Upon drying, the radial shrinkage is 2.2%, the tangential 4.7%. The pinnately compound leaves are borne alternately, and bear up to fifteen oval-lanceolate finely serrate leaflets. The immature fruits are pickled whole for human consumption. The mature nuts are also eaten. Like most walnuts, "J. australis" produces juglone, an allelopathic substance which decreases competition from other plants growing nearby. The concentrated extract of the husk is also used as a vermifuge. Juglans australis Juglans australis, the nogal criollo, is a species of plant in the Juglandaceae family.

Fruit tree forms whilst keeping the tree short and accessible for harvesting. Other shapes such as cordons, espaliers and fans offer opportunities for growing trees two dimensionally against walls or fences, or they can be trained to function as barriers. Some of the following fruit tree forms require training by tying the branches to the required form. Most require pruning to retain the desired structure. However, not all types of fruit tree are suitable for all forms; apples and pears do well as cordons and espaliers, for example, whereas cherries are more suited to the fan form.
