Eureka lemon trees are flowering evergreen trees that bear edible fruit. The Eureka lemon is a hybrid descendant of a true Italian lemon. The tree is native to California. Because the tree grows small and compact, it is popular among home owners and gardeners for its beauty, fragrance and fruit.
Find a location in your yard that receives at least eight to 10 hours of direct sunlight each day. The Eureka lemon tree requires a lot of sunlight in order to grow and develop fruit.
Decide whether you want to grow the lemon tree directly in the ground or in a flower pot. To grow in the ground, make sure the tree has no large plants or trees growing within 5 feet of it. The tree needs open air and ventilation, and large plants in a close vicinity block air flow.
Dig a hole that is 2 inches deeper and 2 inches wider than the lemon tree's root ball if you are planting directly in the ground. Eureka lemon trees adapt to any soil conditions except for very wet soil. If the hole you dig fills with water within five minutes you will need to find another place to plant the tree. If planting the tree in a container, use a container that is at least 15 inches in diameter. You will need to re-pot into a larger pot each spring.
Water the Eureka lemon tree every three or four days. During the summer, water more often if the soil is dry to the touch.
Prune the tree every spring to keep the size and shape manageable. Pruning also encourages new growth and fruit production. Use gardening shears to remove dead wood and thin, spindly branches. Trim long, unruly branches so that they fit with the desired shape of the tree.
Protect the tree in the event of frost during the winter. For trees grown directly in the ground, pile 4 to 6 inches of mulch over the roots and wrap the canopy with a cotton sheet or light blanket. Trees that are grown in flower pots can be brought into the house until the last threat of frost has passed in spring.
