Lemon is the most versatile and widely grown citrus in Australian home gardens. Both Lisbon and Eureka lemons are reliably productive across most of Australia, producing fruit year-round in subtropical climates and mainly in winter in temperate regions. Meyer lemon, a hybrid with a sweeter, thinner skin, is popular for smaller gardens and pot growing.

Lemons need full sun and well-drained soil. Regular fertilising with citrus food and consistent watering during fruit development gives the best results. Most lemons are grafted onto rootstock for disease resistance and improved performance. Grafted trees typically fruit within 2-3 years of planting.

Common varieties available include Eureka (seedless, thin-skinned, year-round fruiter), Lisbon (hardier, slightly more acidic), and Meyer (compact, sweet, tolerates cooler conditions). Dwarf and semi-dwarf versions are available for pots or small gardens.

Lemons are among the most widely stocked fruit trees in Australia, available from the majority of nurseries year-round.
