How to Care for a Dwarf Washington Navel Orange Tree

Overview

The dwarf Washington navel orange tree is grown not only because of its small size, which makes its perfect for almost any location, but for high quality oranges that are excellent for juicing and eating. The dwarf Washington navel orange tree can grow to a height of 8 feet and can be planted and grown outdoors in USDA zones 9, 10 and 11. If you live in other areas, you can still successfully grow this tree in a container indoors.

Step 1

Place the orange tree in an area where it will receive full sun for most of the day. Citrus trees need the heat of full-sun conditions to thrive and produce plentiful fruit.

Step 2

Water the tree every other day if planted in a container, and once weekly if planted in the ground. Citrus trees require a lot of water.

Step 3

Fertilize the orange tree once per month during May, June and July to keep the orange tree stocked with vital nutrients. Use a fertilizer designed for citrus trees, which you can purchase at your local garden specialty store or plant nursery.

Step 4

Prune the orange tree throughout the growing season to relieve it of any dead, dying or broken limbs. Make your cut where the limb joins the main trunk.

Step 5

Bring the orange tree indoors or into a greenhouse before the first frost if it is being grown in a container. If the tree is planted in the ground, apply a 6- to 10- inch layer of mulch around the base of the tree and wrap the trunk in burlap if the winter temperature dips below freezing. If your area never experiences freezing temperatures, adding only the mulch will suffice.

Step 6

Remove the burlap cloth in early spring if necessary after the danger of frost has passed. You may either leave or remove the mulch.
