Pruning as A Strategic Practice to Boost Fruit Yield

Espaliered apple trees at Mt. Originally it defined the trellis, or frame, the tree was trained to but this meaning is no longer used. This horticultural technique trains woody trees or shrubs through pruning and tying to create two-dimensional plants, often in specific patterns. Because a plant pruned in this way uses far less space, it is ideal for small gardens and in narrow spaces where spreading trees or shrubs will not fit. When planted next to a south-facing wall, the slightly warmer microclimate the wall radiates heat and provides shelter may allow some plants or cultivars to be planted in colder regions than they would normally be able to survive or fruit because the season is a little too krátký.

Today, espaliers are used primarily as decorative accents in the landscape. They function as living sculptures — but less involved than topiary — and are especially effective against blank walls. Espalier differs from topiary in that pruning creates a structure or skeleton of the tree, while topiary only forms a shape or silhouette.

In winter the geometric form of the bare branches are especially noticeable and decorative. They can be used to disguise less-than-attractive walls or fences or to screen views of utility areas. Free-standing forms make elegant fences or unique vertical accents. Espalier is much more popular in Europe than in the U. As a fence in the kitchen garden at Mt. This ancient practice may go back as far as the early Egyptians tombs from about BCE have been found with paintings of espaliered fig trees , although many believe the Romans originated the technique.

It was commonly used in the Middle Ages in Europe to grow fruit inside walled monastery gardens or castle courtyards without filling the open space. The classic European styles can be traced back to the 16 th and 17 th centuries where they were developed in such marginal climates as northern France and southern England for more practical fruit production.

The best candidates have long, flexible branches and ornamental flowers or fruits. Fruit trees are the most common subject. The intensive pruning directs energy away from vigorous vertical growth into the shorter, lateral fruit-bearing spurs, resulting in heavier yields than on ordinary trees.

Because they are less susceptible to breaking branches, espaliered trees can have an incredible life span — some espaliered apple trees are still producing fruit after years!

Some other advantages to espaliering fruit trees include being able to grow several different cultivars in the space of a single normal tree for greater diversity in fruit types and cross-pollination requirements; the trees bear earlier and for a longer time with deeper fruit color; fewer pest problems as air circulation is enhanced and any needed treatments are more easily applied; and harvest is much easier.

Espaliered trees can grow very old. Fruit trees that bear fruit on long-lived spurs are easiest to espalier. Apple and pear trees are the traditional espalier subject because their spurs live for years producing fruit although certain cultivars are better than others and they have supple, easily trained new growth, but other fruit trees that sometimes are espaliered include fig Ficus carica , peaches, cherries and pomegranates.

Plums, nectarines and apricots require more careful pruning. Dwarf cultivars are easier to train than standard size trees. Almost any woody plant with long flexible branches can be used for espalier. Even climbing roses could be used. There are six traditional patterns used in espalier, with many variations on these basic designs.

Normally only a single design is used within a landscape. The traditional cordon L , fan C , and informal R styles of espalier. The different patterns are created by pruning to remove unwanted branches and training forcing others into the desired position.

The highly symmetrical, formal designs require much more effort than the informal types. Some plants or cultivars are more suited to certain patterns than others because of their natural growth form, so will require less effort to train and maintain if well-matched. The more complex patterns take longer to develop. Espaliered tree at Palais Het Loo, Netherlands. Espaliers are trained on a strong supportive form of wood or galvanized wire.

Almost any flat surface can be utilized: a wood or chain link fence, brick walls, the side of a garage, home or other building as long as a support structure can be attached to it. Free-standing trellises or even just wire stretched between posts can be used can be used independent of a flat surface. Supports are placed in specific locations depending on the pattern and the plants are pruned and tied to the supports as they grow. Espalier requires dedication to pruning to develop a beautiful and productive tree.

The basic framework of simple designs may be established in three or four years, while intricate designs will take longer. To develop your own espalier, choose a young tree without much branching, as this will require much less effort to manipulate.

Growth is redirected by pruning to buds that face the direction you want the plant to grow. Branches are moved into place and tied onto the supports in spring and early summer, while branches are still young, soft and easy to manipulate. This often has to be done gradually over a period of time each spring. The ties — of soft string, strips of rags, rubber grafting bands, plant ties, or raffia — should be checked periodically every few months and loosened if restricting growth or damaging the branch.

The ties are removed once the final form has been achieved. Once the desired overall shape is achieved, it is maintained by simple, minor pruning once a month to remove all stray branches and twigs that are growing perpendicular to the flat plane or out of the pattern.

Specific directions for pruning the different patterns can be found in various books. Maintenance for espalier plants is the same as for normal plants of their type, except for the more intensive, regular pruning and shaping which never ends. Ask Your Gardening Question.

Cordon espaliering can be used to form living fences or to increase yield in small orchards. Palmetto Verrier — branches are shaped into a U as the horizontal branches are turned up at the ends. This creates nice definition between trees planted against a wall. This is best for spaces requiring vertical coverage or in square spaces.

Candelabra — several vertical branches arise at regular intervals from a low horizontal branch coming off the central trunk, forming a candelabra shape. Informal — more naturally shaped, but still in a single plane.

This requires only simple pruning. Belgian Fence — three or more V-shaped espaliers are woven together into a fence for a lattice effect. The two trees on the ends are modified Vs for finished ends. To rake or not to rake?

Special Horticultural Practices in Flower Crops

The main trunk is allowed to develop without interruption. The first branch is allowed to grow at 45 to 50 cm height from ground level and other branches are allowed to grow on main stem at a distance of 15 to 20 cm. The main trunk is beheaded, when the plant attains a height of 40 to 50 cm.This system leads to a spreading structure, through with somewhat weaker crotches facilitating thinning, spraying, picking, removal of diseased portions.

Focusing on apple and pear trees, specific advice is also given for pruning stone fruits trees eg cherries , cobnuts, walnuts and mulberries. There are sections on the differences between spur bearing, tip bearing and partial tip bearing trees and on the different pruning methods for each type of tree.

Pruning shade trees in landscapes

Coppicing and pollarding are two types of pruning for trees and shrubs. For hundreds of years, these traditional British methods were used for wood production. Coppicing was ideal for getting wiry stems perfect for baskets, fencing and hurdles; pollarding was a great way to obtain firewood to withstand the harsh winter season. Both of these woodland techniques are still used today, often for ornamental reasons on trees and shrubs whose new growth is brightly colored , such as shrubby dogwoods shown: Cornus sericea and willows. Although the outcome is similar, these processes are different, mainly due to the location on the plant where the pruning begins.

Printable PDF The reasons to prune trees and shrubs include: to keep the plant healthy, to remove any dead and dying branches or twigs, the restoration of overgrown plants, to maintain a natural shape, and to increase light and airflow through the plant. Begin by removing any dead and dying branches or twigs and any branches that cross or rub together. Always consider the natural shape of the plant. Some terminolgy on an espalied tree.

Pinching, otherwise known as tipping, is a pruning method generally used on young plants to encourage branching. Too, these terms can be used when referring to the removal of plant buds to discourage branching. Confusing, right? Once explained, these techniques are easy to understand and valuable to use. When a plant begins to grow from seed, it usually breaks through the soil as a single stem upon which leaves begin to form.

Pruning should be a routine part of landscape maintenance practices. Proper plant selection and knowledge of plant varieties and their size at maturity will help eliminate the need for major pruning. If a tree needs to be pruned several times each year to control its size, it may be the wrong species for a particular location. Plants are pruned for a number of reasons, so determine why you are pruning a plant before making that first cut.
