Fuji apple trees grow in full sun and well-draining soil. Plant Fuji apple trees on level ground or a slight rise where water will drain away from the roots. Avoid low areas that tend to collect moisture and frost. According to the North Carolina State University, trees planted in a frost pocket are at risk of flower damage in the event of a late frost. Before planting, select an area that is away from houses, wooded areas and other shad trees. Fuji apple trees flower in the spring and bear fruit in the late fall.
Clear the planting area of weeds, grass or other plants. For young trees, clear a circular area with a 4-foot diameter. Dig up and loosen the soil in the planting circle to a depth of 18 inches.
Dig a hole in the center of the planting area that is twice as big as the root ball of your young Fuji apple tree sapling. Dig the planting hole 2 feet deep. Plant Fuji apple saplings when they are 1 year old and 4 to 6 feet tall, according to the North Carolina State University Extension.
Look at the trunk and determine the place where the graft was performed. Nursery trees are created by grafting the fruit tree onto a strong root stalk. You will see an area where the bark changes texture and there is an obvious joint. Hold the sapling so that the graft is above the soil line and fill in under the roots until the tree rests in the hole.
Spread out the roots so that they lay flat in the hole and are not wrapped around the root ball. Fill in the soil around the roots, pressing it down periodically to eliminate air pockets around the young roots. Keep the graft 2 inches above the final soil line.
Pat down the soil so that the Fuji sapling is secure in the planting hole. Water the planting area to settle the soil around the roots. Soak the area until the soil is damp at least 18 inches deep.
Add 1 pound of 10-10-10 fertilizer to the soil around the planting area. Keep the fertilizer 6 inches away from the base of the stem to avoid burning the trunk. Fertilize in the spring before the tree begins to put out new growth.
Add 2 pounds of fertilizer in the second year. Add an additional 1 pound of fertilizer each year until you are applying 6 pounds per year. Once you reach 6 pounds per year, continue that amount for the life of the tree. Consult the manufacturer's instructions on the package to determine the correct application method.
Keep a 4-foot diameter circle around the trunk clear of weeds. Fuji apple trees are shallow rooted and do not thrive in a competitive environment.
Prune in the late winter after the last frost has passed. Late-winter pruning will stimulate the tree to produce new growth. Use a clean pair of shears or pruning saw and thin any branches that are crossing or touching one another. Take out any dead or diseased branches.
Thin the developing fruits when they are about 1/4 inch across. Take out all but one fruit from each cluster to improve the fruit quality. Pinch the fruits off with your finger nail or use a small pair of nippers.
