Apple and pear trees are usually pruned to a central leader main trunk and scaffold side branches Figure 1. Side branches need to have wide angles of attachment to the trunk to be strong. Each year, pruning and training is needed to produce high quality fruit and maintain tree health. The tree canopy requires training to allow leaves to be exposed to sunlight so they can make sugars for tree growth and fruit production.

After years of experimentation, Terence Robinson believes he knows what a modern apple tree should look like. It sits along a three-wire trellis with other trees, spaced about three feet apart, in rows 11 feet apart, on an M.
It fruits early, bearing 15 to 20 apples in its second year. Growers who plant trees like this have to learn a different training and pruning system, but if they plant the right varieties they should make money. The Cornell University horticulturist explained in detail how to establish such an orchard, how to prune and train it and how much income it should provide.The system evolved out of a period of experimentation, by both growers and horticultural researchers, that started 50 years ago with the abandonment of seedling rootstocks and the search for trees that were more manageable, bore fruit sooner and yielded more per acre.
Tree densities soared from as few as 35 trees per acre on by foot spacing to more than 2, in some systems, and heights fell from 50 feet down to pedestrian size — the size of bushes. Investment per acre skyrocketed as trees per acre increased.
Not everything worked. Trees could be too short as well as too tall, too dense as well as too spaced out. The planting system achieves the goals of very high early yields, high sustained yields and excellent fruit quality, while moderating the initial investment compared to the super spindle system.
The important components of this system, as Robinson lists them, are: 1 high planting densities, 2 dwarfing rootstocks, 3 highly feathered nursery trees, 4 minimal pruning at planting, 5 bending feathers and branches below horizontal, 6 no permanent scaffold branches and 7 limb renewal pruning to remove and renew branches as they get too large.
Tree densities can vary from as many as 1, trees per acre on a 3- by foot planting to per acre on a 4- by foot planting. The proper density considers the vigor of the variety and rootstock and the strength of the soil, Robinson said.
Closer spacing is recommended for weak and moderate vigor varieties such as Honeycrisp, Gala and Red and Golden Delicious, and wider spacing for vigorous McIntosh, Fuji, Mutsu or tip-bearing Rome, Gingergold, Cortland varieties. Trees should be on dwarfing rootstocks such as M. Newer rootstocks from the Cornell Geneva series G. Within rootstocks, however, there are vigor differences.
Weaker clones are recommended on virgin soil and with vigorous varieties, while more vigorous rootstocks should be used with weaker scions or on replanted ground, he said.To achieve bearing in the second year, high-quality trees must be planted, he said. Whips and small caliper trees will not bear significant quantities of fruit until year four or five.
Many nursery trees have three to five long feathers instead of 10 short feathers. The tree with few long feathers requires more branch management. The most important method of inducing cropping and reducing induced juvenility is tying down the scaffold branches below horizontal, he said. At planting time, all the feathers must be weighted or tied down to induce cropping and prevent them from developing into scaffold branches. If the feathers are not tied down, limbs become too strong and invigorated, making it difficult to contain the tree, he said.
After the initial tying down, new lateral branches that arise along the leader will not need to be tied down. If not pruned, they will bend with cropping, he said. For slow-growing and biennial bearing varieties like Honeycrisp, crop loads should be half that used with Gala.
The tall spindle tree is essentially a foot trunk with small fruiting branches along its length, Robinson said. To achieve this in three years, the central leader is not cut headed at planting. Given the size of the tree from the nursery, 5 to 6 feet tall, it is already half its mature height at planting time.
This tall, thin tree needs support, or when it is fully leafed out it may break in the wind, he said. A three- or four-wire trellis is needed before the first leaves appear. Because of tree density, individual tree stakes are prohibitively expensive. The tree is tied to the trellis and is not headed until reaching its mature height, about 10 feet in year four or five.
The narrow, slender shape helps ensure most of the canopy is exposed to good light, resulting in excellent fruit quality, he said.To assure the development of a replacement branch, the large branch should be removed with an angled or beveled cut so that a small stub of the lower portion of the branch remains.
From this stub a flat, weak replacement branch often grows. When this style of pruning is repeated annually, the top of the tree can be composed completely of young fruitful branches, thus maintaining the conic shape of the tree. Testing of the tall spindle system began at Geneva in , Robinson said.
Since then, it has been the second highest yielding system — behind the super spindle — but the most profitable. That was achieved while planting less well-feathered trees, which were not available for planting 10 years ago.
Newer plantings, with trees planted with more feathers, have achieved higher yields, he said. In orchards planted in with trees with seven to eight feathers, after four years McIntosh and Honeycrisp are yielding at twice the levels of the traditional vertical axis trees. McIntosh yields in the fourth leaf reached bushels per acre and Honeycrisp reached bushels per acre, he said. Troon Vineyard makes wine with minimalist approach.

Once Oklahomans established their roots in the state, the hardy, adaptable pear tree soon followed. Productive and long-lived, the old cultivars produced fruit that today would likely not be up to the quality standards of a commercial orchard or present day consumers. Today Oklahomans have many more choices of pears to grow. There are three main types of pears — European, Oriental Hybrid, and Asian. The most common is the European pear, Pyrus communis , which has the typical pear shape.
For smaller gardens, apples, pears, gages, plums, damsons and cherries are all available as self-fertile Minarettes. These bear fruit on short spurs along the length of a vertical stem, and many can be grown in patio pots.
Join us on Facebook. Growing apple trees in containers can be very rewarding.

To produce quality fruit, fruit trees such as apples, pears, cherries and plums need regular pruning in their first few years to develop healthy growth and well-spaced branches, and continuous minor pruning there-after. There are many different ways to prune fruit trees that result in good quality trees such as central leader, multi leader, open center, espalier and cordon styles, and we recommend that you research other methods if you are interested. This is an overview of central leader training, which results in an attractive fruit tree for ornamental home use. It is important to be willing to sacrifice maximum fruit production for the first few years in order to establish the proper form for your fruit tree.
As far as shape is concerned, pots which narrow towards the top are definitely not recommended because it makes transferring the plant to a larger pot very.
I get asked a lot about how to prune older trees, particularly from gardeners who have moved to a new house and have inherited unruly and unproductive specimens. The other common issue is dealing with a older tree that has been pruned too hard either by a previous owner or by the gardener themselves. I hope this article will help avoid pruning problems while also giving some assistance in correcting mistakes that have already been made. Old and unproductive trees in a commercial orchard would normally be removed a well pruned new tree will produce far more fruit in the long run but in the garden there are often other things to consider.
Trees can be distinguished on the basis of several factors like their height, support and rootstock. A dwarf fruit tree could be feet however a miniature tree remains between feet keeping it smaller. You may also like to see fast growing fruit trees and fruit bearing trees. Dwarf fruit trees that are commonly available include nectarine, olive, pear, peach, apricot, apple, cherry, fig, citrus and quince. The dwarf fruit trees usually on the smaller trees produce regular sized fruits but while buying such trees the end use is also considered.
A lot of people think you can only grow fruit trees outside, but there are actually a variety of indoor fruit trees you can grow right in your own living room. Like regular houseplants, these trees can provide you with fresh oxygen and beautiful foliage.
The truth is that some crops really do need full sun, but there are also quite a few shade-tolerant fruit trees. Although commercial growers seek to maximize fruit production by minimizing competition, backyard orchardists can achieve excellent results in partial shade.Plentiful sunshine allows trees to convert energy from light into sugar to fuel flower production and fruit development. And, although the green skin on immature fruit can perform photosynthesis, the fruit still requires supplemental sugars provided by nearby leaves as its primary source. The quality of individual fruits also increases with light exposure, regardless of the nearby leaves. Fruits exposed to optimal light conditions attain higher sugar levels, increased flavor complexity, and a greater depth of color.
