New South Wales (NSW) features a mostly temperate climate with humidity and heat more prevalent in the northern part of the state. The area around Sydney to the south is cooler, especially in the winter, which allows for the growth of more cold-season fruit trees. The most popular fruit trees in the state, however, are semitropical and are abundant both in the wild and in residential backyards.
Papayas are grown from one- or two-year-old transplants in New South Wales. They are planted in the fall (March to May) so they can get established before the weather gets cold. Most papayas grown in NSW are hybrids, selected for the coolness of the climate compared to more tropical regions in Australia. A healthy mature papaya tree can provide up to 75 lbs. (34 kgs) of fruit per season.
Pomegranates are cultivated mostly by home growers and have never developed into a substantial commercial crop in Australia. Pomegranates are best grown from nursery transplants, as there is substantial variability in characteristics among plants grown from seeds. Both the flowers and the fruit are attractive. Pomegranates can be harvested for several weeks in summer and reach full production at between three and five years.
Avocados are a common sight growing along roadsides and in gardens in New South Wales, especially on the northern end of the coast. The main avocado variety grown in NSW is the Hass avocado, discovered as a mutation in California in 1926. Every Hass avocado tree in existence is a clone of that initial tree. In the north of NSW the avocado crop begins to ripen in April; the farther south, the later the beginning of the ripening season. Avocado trees are self-fertile and therefore can be planted alone in a garden.
