While we like to think of this as an Aussie Lemon, the Eureka lemon actually started life in Sicily, Italy, before being selected and released to the world from lemon trials conducted in California in 1858. One of the most popular lemon varieties in Australia, Eureka is also a great way to extend your lemon harvest, cropping almost year round in some climates. Eureka is suited to milder climates where frost is unlikely.
Citrus grow best in open positions where they receive full sun, good drainage and shelter from strong winds. They prefer a frost free environment although will tolerate light frost once established. Citrus are well suited to pot culture and are no less productive when kept at 2m tall and 2m wide which also makes maintenance and care more manageable. Always use good quality potting mix in a pot. Citrus have a shallow fibrous root system and underplanting and cultivation below the tree should be avoided. Fertilise monthly with a complete, slow release, pelleted fertiliser all year round. Mulch to conserve moisture. Supplementary water is required during the warmer months. Prepare soil prior to planting by digging a hole twice as wide and deep as the root ball and enriching with compost and pelleted complete fertiliser. Apply seaweed solution after planting. Grafted on to Citrange rootstock which performs well in clay loams and shows tolerance for nematodes. Fruit size and quality from trees on this stock is very good.
