A Eureka lemon tree is a lemon tree that produces green fruit with gold streaks and has pink flesh and clear juice. It produces few lemons until it reaches 4 to 5 years of age.
The Eureka lemon tree has apple green leaves that have light yellow edges. The tree grows up to 15 feet tall but should be pruned back every 4 years to keep it small enough for a container. The Eureka lemon tree can't take colder temperatures and needs to be brought indoors during the colder months.
The Eureka lemon tree requires sandy soil with a bit of organic matter mixed in. A nitrogen-based fertilizer should be applied before the tree flowers in the spring.
