Information on Navel Orange Trees

The navel orange is a popular fruit for snacking.

Much of the landscape in warm climates in the United States is dotted with fragrant citrus trees. Naval orange trees grow to about 25 feet tall and produce hundreds of sweet, juicy oranges every year.

Geography

Naval orange trees are grown in warm climates, including California, Florida, Texas and Washington. Mature trees can survive overnight temperatures as low as 25 degrees Fahrenheit, but the fruit is damaged by temperatures below 30 degrees, according to Purdue University.

Time Frame

Navel oranges generally are harvested between November and January and they are some of the earliest oranges, compared to other varieties that ripen later in the winter. Trees might begin to start producing about 10 lb. of fruit in their third year after being transplanted, increasing to 100 to 150 lb. by the 10th year.

Fruit

Navel oranges are characterized by a small immature fruit embedded in the end of the orange. When this is removed, it leaves an opening shaped like a navel. The fruit has thick skin, is relatively easy to peel, usually seedless and is sweet although not very juicy. Navel oranges are typically eaten fresh, rather than being juiced.
