Citrus made easy for growers, nurseries, and distributors

Washington navel orange trees are cold-hardy to around 28°F, making them ideal for USDA zones 9–11. In colder climates, dwarf varieties can be grown in pots and brought indoors during the winter months. TreeSource’s dwarf Washington navel orange trees typically grow to about 6–8 feet in height, making harvesting simple and care more accessible than with standard-sized citrus trees.

Yes. Dwarf trees can be custom-ordered on Flying Dragon rootstock (order minimums apply). Semi-dwarf rootstocks such as C35 are readily available. Contact the sales team for more information about what we have in stock.

Citrus trees like Washington navel oranges do well in pots, and that naturally dwarfs the tree. A 15-20-gallon pot or a ½ wine barrel is a great size, and since the root system is restricted, the tree will grow smaller.

A standard Washington navel orange tree typically grows to 15 to 20 feet tall and spreads up to 15 feet wide when planted in the ground under optimal conditions. A dwarf Washington navel orange tree, especially one grafted onto dwarfing rootstock like C-35, generally reaches 6 to 8 feet tall, making it much easier to manage in home gardens or containers. The exact size can vary depending on rootstock, pruning, climate, and care.

A Washington navel orange tree usually begins producing fruit about two to three years after planting, depending on its initial size, the rootstock it's grafted to, and the quality of care it receives. The main fruiting season occurs from December through March, making it one of the earliest ripening sweet oranges available.

In some climates, especially those with mild winters, the fruit can remain on the tree into April or even May without a loss of flavor or texture. Washington navels do not continue to ripen once picked, so it’s best to harvest them when their deep orange color develops fully and the fruit feels slightly soft to the touch. Regular watering, balanced fertilization, and full sun exposure all contribute to consistent yields and high-quality fruit.
