Classic backyard citrus. Sweet oranges need more heat than lemons for sweetness development - coastal Melbourne oranges are noticeably more tart than those from Mildura or the Riverland. Navel oranges (seedless, eating) and Valencia oranges (juicing, summer fruit) are the main types. Trees are medium-sized, attractive, and productive for decades. Grafted onto appropriate rootstock.
