The Washington navel orange tree is one of the most popular citrus trees to grow in the world, and is the most beloved orange tree for backyard growers. This tree is easy to grow and requires less care than other orange trees. Moreover, the Washington navel orange tree also outperforms most other citrus trees, so what’s not to love?
Let’s dive in and learn all about the amazing Washington navel orange tree!
History of the Washington Navel Orange Tree
When you think of an orange and picture one in your mind, you’re probably thinking of the Washington navel orange without even knowing it. Ironically, however, this beloved citrus tree isn’t originally from Washington at all. In fact, the Washington navel orange tree was first imported to the United States from the Brazilian city of Bahia in 1870. For this reason, it’s sometimes called the “Bahia.”
Most experts believe that the Washington navel orange tree came from a bud sport that was found in the early 1800s in a Selecta orange tree grown by missionaries. When the Washington orange tree arrived at the U.S. Department of Agriculture in Washington, D.C., scientists propagated it, and trees were sent to Florida and California.
The trees that went to Florida failed to flourish, but the ones that made it to a woman named Eliza Tibbets in Riverside, California thrived in the ideal climate there.
Here’s another super cool fun fact about these legendary orange trees: the Washington navel orange tree doesn’t have seeds, so it can’t be grown from seed. Washington navel oranges have to be cultivated through grafting to seedling rootstocks or budding. Because of this, almost all of the Washington orange trees grown in California originate from the first two trees that were sent to Eliza Tibbetts.
One of the original trees of Mr. Tibbetts is still alive and that tree is an official registered historical monument in Riverside.
Washington Navel Oranges and Tree Characteristics
Most navel orange trees aren’t extremely vigorous trees, and the Washington navel orange tree is no exception to that rule. Their canopies are round and drooping and the tree grows to a moderate size when mature.
The large round oranges this tree produces have a pebbled orange rind that peels easily. The navel, which is actually a small secondary fruit, will occasionally protrude from the fruit’s apex.
Washington navel oranges ripen in the late fall and early winter, but these oranges will hold well on the tree for up to three months after maturing with no sacrifice of their integrity or quality. They store very well, too.
The Washington navel orange tree has fragrant and sweet-smelling white flowers. The foliage on this tree is evergreen.
Where To Buy Washington Navel Oranges and Trees?
You can buy Washington navel orange trees online, but be quick, before they sell out! You can find them at the following online nurseries:
You can find Washington navel oranges and other varieties of navel oranges in grocery stores, organic markets, and fruit stands. These oranges are in season from autumn through spring.
The Washington navel orange tree grows well in USDA Hardiness Zones eight through 10, although some experts argue that it does well in zone 11 as well. However, it should be noted that this tree didn’t thrive in Florida because it’s not well adapted to semitropical hot climates. So the fruit that the Washington orange tree produces when grown in Zone 11 tends to be sub-par.
If you’re going to grow your Washington navel orange tree in a container, you can extend the available growing zones for this tree down to zone four.
Size and Spacing
A full-sized Washington navel orange tree will grow to be between seven and 15 feet tall. The width of a mature tree is between eight and 12 feet. The dwarf variety of the Washington navel orange tree reaches a height of between three and six feet tall.
The Washington navel orange tree doesn’t require a pollinator. Note that the flowers on the Washington navel orange tree lack viable pollen, so they will not serve for pollinating other citrus trees, either. Since they lack viable ovules and functional pollen, this citrus tree produces fruits that are seedless.
The Washington navel orange tree is delightfully easy to grow. This tree needs fertile, well-drained soil to thrive. If you grow the tree in cooler climates, you will have to move it indoors when it gets cold.
Like most orange trees, the Washington navel orange tree thrives in full sun. Your tree needs between eight and 12 hours of sunlight every day.
If you grow your Washington navel orange tree inside, place it beside a south-facing window. Moreover, the area needs to have good airflow. In darker winter months, you can also supplement your tree’s sunlight with grow lights.
If you plant your tree in a container, it will need to be watered more frequently than if you plant it outside in the ground. This tree enjoys low to moderate moisture. However, don’t allow the soil to become soggy. To test the dryness, check the top two to three inches of soil. If your soil is dry to that depth, the tree needs water.

To encourage better fruit production and outward growth, the Washington orange tree needs regular pruning. To prune your tree, cut off the dead, broken, and diseased branches as they develop.
You should also eliminate any crossing or rubbing branches. Doing this will encourage the outward growth habit that is ideal for this tree and allow the sunlight to reach every branch. Find a more detailed guide to pruning an orange tree here!

Preserving Orange Zest
One of the most popular ways to preserve every part of the orange is to dry or freeze the zest for future use. Follow these steps for the best results:
- Zest your Washington oranges and place the zest in a thin layer on a baking tray. Be sure to avoid getting the white pith into your zest because it will give it a bitter taste.
- Bake your zest for 30 minutes to one hour at 170 degrees Fahrenheit.
- Store in a cool, dark place in an airtight container.
Another option is to simply let your zest air-dry naturally. Follow all the instructions above and skip the oven part. Your zest should be dry in a couple of days.
Your zest will stay flavorful for up to a year, and is sublime in fruit bread and quick breads.
