A popular and ideal citrus for the home garden. The Eureka lemon might be the most commonly grown lemon tree, popular for the fact it bears several crops throughout the year - winter, spring and a main flush of fruit in summer. This lemon is a vigorous grower with almost no thorns. Full size trees can grow up to 5m tall so ensure there is adequate space when planting. Citrus are best grown in a full sun position whether it is in the pot or the garden, with well-draining soil and frequent fertiliser applications over the warmer months.
