Before you plant

These conditions determine whether it will thrive.

Required microclimate

Placement is part of the growing system.

Zone A — morning sun, afternoon shade, at the east end of the sunnier south-facing side. Shields thin skin and variegated foliage from west sun, and gives blood oranges the cooler afternoons they need to color.

Cold hardiness

Cover while young

Like most sweet oranges, leaves take damage in the mid 20s. It ripens in late October, weeks before Washington, so the fruit is usually picked before any frost. Cover it its first two or three winters.

Leaves and wood: damaged below 25°F · Blossoms and fruit: below 28°F

Heat tolerance

Needs afternoon shade

Navels are the most heat-sensitive oranges here. Days in the 90s during April and May bloom make the tree drop much of its young fruit, so water deeply in spring and give it afternoon shade rather than full west sun.

Planting & stewardship

How to help Fukumoto navel orange thrive

1
Verify both the named cultivar and rootstock on the nursery tag before planting.
2
Whitewash newly exposed bark and protect cold-sensitive trees during hard freezes.
3
Feed in several light applications during the active season rather than one heavy dose.
4
Let fruit color and flavor—not a calendar date alone—confirm harvest readiness.
