How to grow dwarf apple trees

Updated February 21, 2017

Dwarf apple trees are a great way to grow apples in a small space. However, size is not the only advantage they offer gardeners. Dwarf apple trees are also easier to prune, spray and harvest. They also bear fruit easier -- in just 3 or 4 years as opposed to 7 or 8 years for standard apple trees. Dwarf apple trees are not grown from seeds but are created by grafting a regular apple tree onto the rootstock of a dwarf tree, which is why all dwarf trees produce standard size apples. The grafted tree is then grown in a nursery for at least a year until it is large enough to be sold.

Decide if you want a dwarf tree or a semi-dwarf. Semi-dwarf trees grow about 4.5 to 6 m (15 to 20 feet) tall but are more vigorous and hardier than dwarf trees. They will produce about five bushels of apple a year. Dwarf trees will grow about 3 or 3.6 m (10 or 12 feet) tall and produce about two bushels of apples each year. However, they have weaker roots and need more care.

Purchase trees from a reputable garden dealer or nursery. If possible, purchase trees that are dormant. Look for one year-old trees that are about 1.2 to 1.8 m (4 to 6 feet) high and at least 1.5 cm (5/8 inches) in diameter.

Buy at least two types of apple tree because most are considered "self-unfruitful." This means that they are unable to pollinate themselves and require pollen from a different variety to produce apples. Even varieties that are self-pollinating, such as Golden Delicious, Jonathan and Yellow Transplant, will do better when self-pollinated.

Dig several holes for your trees. Make sure they are far enough apart. Full dwarf apple trees should be 2.4 (8 feet) apart with rows at least 3.6 m (12 feet) apart. Semi-dwarf trees should be 3 to 4.2 m (10 to 14 feet) apart with 4.8 m to 6.6 m (16 to 22 feet) between rows. Holes will need to be wider than they are deep to allow the roots to spread out.

Plant trees in an area of full sun with a soil pH of approximately 6.5. Trees should be planted in the spring while they are still dormant. The graft union (a diagonal scar on the trunk of the tree) should be 2.5 to 5 cm (1 to 2 inches) above the soil surface. Do not fertiliser the planting hole.

Stake trees to provide them with support. This is especially important if the trees were grafted onto M.9 and M.26 rootstock.

Water all trees thoroughly.

Prune your tree regularly. Remove any branches that grow below the graft union.

Wait. In about 3 or 4 years you should have all of the apples you desire.

Warning

Several varieties of apple trees will not serve as pollinators including Rhode Island Greening, Gravenstein, Mutsu, Roxbury Russet, Jonagold, Spigold, and Baldwin. All apple trees need at least one month of cold weather to grow.
