How to Care for a Fuji Apple Tree


Fuji apple trees, which offer a sweet and juicy, yet somewhat tart fruit in the fall, are generally not hard to take care of. Outside of the chilling requirements and growing day requirements, they tend to act much like any other apple tree variety. Still, it is important to understand not only how Fuji apple trees are like other apple trees, but also how they are different. Otherwise, the sweet, juicy fruit you have come to expect from the grocery store cannot be duplicated at home.

Fuji Apple Tree Care

Step 1

Determine whether Fuji apple trees can grow adequately in your location. In most cases, the tree will need at least 350 chill hours in order to have fruit set properly. Therefore, you can normally grow apples in USDA plant hardiness zones 5 through 8. Chill hours are defined as those hours when the temperature is less than 45 degrees F.

Step 2

Plant Fuji apple trees in the fall before the first freeze happens. This gives the tree's roots a chance to establish themselves while the rest of the tree is in its dormant period. Thus, it does not have to compete for resources.

Step 3

Dig a hole approximately twice the size of the tree's root ball. Remember to plant the tree no deeper than it was before being transplanted. Use water to settle backfill dirt part of the way through the process before filling in the rest of the hole.

Step 4

Watch for pests and especially fungal infections that can afflict Fuji apple trees. Apple scab and apple cedar rust are a couple of the most common fungal infections that inflict Fuji apple trees. Insect pests include aphids and caterpillars..

Step 5

Spray a fruit tree fungicide or fungicide/pesticide mix if these or other Fuji apple pests become problems. The spraying can be done every two weeks after leaves bud in the spring, but do not spray insecticides during flower blooming or bees will not be able to pollinate adequately.

Step 6

Prune trees in the winter so that there is one single dominant leader going up the center. Also, eliminate any crossing branches and make sure there is enough room between branches for adequate light and air movement. This will help maintain healthier branches and fruit and possibly help prevent some fungal infections.
