Pleaching or plashing is a technique of interweaving living and dead branches through a hedge creating a fence, hedge or lattices. [1] Trees are planted in lines, and the branches are woven together to strengthen and fill any weak spots until the hedge thickens. [2] Branches in close contact may grow together, due to a natural phenomenon called inosculation, a natural graft. Pleach also means weaving of thin, whippy stems of trees to form a basketry effect. [3]
Pleaching or plashing (an early synonym) [4] was common in gardens from late medieval times to the early eighteenth century, to create shaded paths, or to create a living fence out of trees or shrubs. [1] Commonly deciduous trees were used by planting them in lines. The canopy was pruned into flat planes with the lower branches removed leaving the stems below clear. [1] This craft had been developed by European farmers who used it to make their hedge rows more secure. [5] Julius Caesar (circa 60 B.C.) states that the Gallic tribe of Nervii used plashing to create defensive barriers against cavalry. [6]
In hedge laying, this technique can be used to improve or renew a quickset hedge to form a thick, impenetrable barrier suitable for enclosing animals. It keeps the lower parts of a hedge thick and dense, and was traditionally done every few years. [7] [8] The stems of hedging plants are slashed through to the centre or more, then bent over and interwoven. The plants rapidly regrow, forming a dense barrier along its entire length.
In garden design, the same technique has produced elaborate structures, [9] neatly shaded walks and allées. This was not much seen in the American colonies, where a labor-intensive aesthetic has not been a feature of gardening: "Because of the time needed in caring for pleached allées," Donald Wyman noted, [10] "they are but infrequently seen in American gardens, but are frequently observed in Europe."
After the second quarter of the eighteenth century, the technique withdrew to the kitchen garden, and the word dropped out of English usage, until Sir Walter Scott reintroduced it for local colour, in The Fortunes of Nigel (1822). [11] After the middle of the nineteenth century, English landowners were once again planting avenues, often shading the sweeping curves of a drive, but sometimes straight allées of pleached limes, as Rowland Egerton's at Arley Hall, Cheshire, which survive in splendidly controlled form. [12]
In Much Ado About Nothing , Antonio reports (I.ii.8ff) that the Prince and Count Claudio were "walking in a thick pleached alley in my orchard." A modern version of such free-standing pleached fruit trees is sometimes called a "Belgian fence": young fruit trees pruned to four or six wide Y-shaped crotches, in the candelabra-form espalier called a palmette verrier, are planted at close intervals, about two metres apart, and their branches are bound together to makes a diagonal lattice, [13] a regimen of severe seasonal pruning; lashing of young growth to straight sticks and binding the joints repeat the pattern.
Smooth-barked trees such as limewood or linden trees, or hornbeams were most often used in pleaching. A sunken parterre surrounded on three sides by pleached allées of laburnum is a feature of the Queen's Garden, Kew, laid out in 1969 to complement the seventeenth-century Anglo-Dutch architecture of Kew Palace. [14] A pleached hornbeam hedge about three meters high is a feature of the replanted town garden at Rubens House, Antwerp, recreated from Rubens' painting The Walk in the Garden and from seventeenth-century engravings. [15]
In the gardens of André Le Nôtre and his followers, pleaching kept the vistas of straight rides through woodland cleanly bordered. At Studley Royal, Yorkshire, the avenues began to be pleached once again, as an experiment in restoration, in 1972. [16]
The word pleach has been used to describe the art form of tree shaping [17] or one of the techniques of tree shaping. [18] [19] Pleaching describes the weaving of branches into houses, furniture, ladders and many other 3D art forms. Examples of living pleached structures include Richard Reames's red alder bench and Axel Erlandson's sycamore tower. [5] There are also conceptual ideas like the Fab Tree Hab. [20]

Fruit trees are grown in a variety of shapes, sometimes to please the eye but mainly to encourage fruit production. The form or shape of fruit trees can be manipulated by pruning and training. Shaping and promoting a particular tree form is done to establish the plant in a particular situation under certain environmental conditions, to increase fruit yield, and to enhance fruit quality. For example, pruning a tree to a pyramid shape enables trees to be planted closer together. An open bowl or cup form helps sunlight penetrate the canopy, thus encouraging a high fruit yield whilst keeping the tree short and accessible for harvesting. Other shapes such as cordons, espaliers and fans offer opportunities for growing trees two dimensionally against walls or fences, or they can be trained to function as barriers.
Pollarding is a pruning system involving the removal of the upper branches of a tree, which promotes the growth of a dense head of foliage and branches. In ancient Rome, Propertius mentioned pollarding during the 1st century BC. The practice has occurred commonly in Europe since medieval times, and takes place today in urban areas worldwide, primarily to maintain trees at a determined height or to place new shoots out of the reach of grazing animals.
A hedge or hedgerow is a line of closely spaced shrubs and sometimes trees, planted and trained to form a barrier or to mark the boundary of an area, such as between neighbouring properties. Hedges that are used to separate a road from adjoining fields or one field from another, and are of sufficient age to incorporate larger trees, are known as hedgerows. Often they serve as windbreaks to improve conditions for the adjacent crops, as in bocage country. When clipped and maintained, hedges are also a simple form of topiary.
Pruning is a horticultural, arboricultural, and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots.
Espalier is the horticultural and ancient agricultural practice of controlling woody plant growth for the production of fruit, by pruning and tying branches to a frame. Plants are frequently shaped in formal patterns, flat against a structure such as a wall, fence, or trellis, and also plants which have been shaped in this way.
Hedgelaying is a countryside skill that has been practised for centuries, mainly in the United Kingdom and Ireland, with many regional variations in style and technique. Hedgelaying is the process of partially cutting through and then bending the stems of a line of shrubs or small trees, near ground level, without breaking them, so as to encourage them to produce new growth from the base and create a living ‘stock proof fence’. The first description of hedgelaying is in Julius Caesar's Commentaries on the Gallic War, when his army was inconvenienced by thick woven hedges during the Battle of the Sabis in Belgium. Hedgelaying developed as a way of containing livestock in fields, particularly after the acts of enclosure which, in England, began in the 16th century. Today hedges are laid to contain livestock without the need for artificial fences, maintain biodiversity-friendly habitats, promote traditional skills and because of the pleasing visual effect of a laid hedge.

Tree shaping uses living trees and other woody plants as the medium to create structures and art. There are a few different methods used by the various artists to shape their trees, which share a common heritage with other artistic horticultural and agricultural practices, such as pleaching, bonsai, espalier, and topiary, and employing some similar techniques. Most artists use grafting to deliberately induce the inosculation of living trunks, branches, and roots, into artistic designs or functional structures.
Pruning shears, also called hand pruners, or secateurs, are a type of scissors used for plants. They are strong enough to prune hard branches of trees and shrubs, sometimes up to two centimetres thick. They are used in gardening, arboriculture, plant nursery works, farming, flower arranging, and nature conservation, where fine-scale habitat management is required. They are typically manually powered, although electric versions are available.
In the French formal garden, a bosquet is a formal plantation of trees in a wide variety of forms, some open at the bottom and others not. At a minimum a bosquet can be five trees of identical species planted as a quincunx, or set in strict regularity as to rank and file, so that the trunks line up as one passes along either face. In large gardens they were dense artificial woodland, often covering large areas, with tall hedges on the outside and other trees inside the hedges. Symbolic of order in a humanized and tamed gardens of the French Renaissance and Baroque French formal gardens, the bosquet is an analogue of the orderly orchard, an amenity that has been intimately associated with pleasure gardening from the earliest Persian gardens of the Achaemenid Empire.
A branch collar is the "shoulder" between the branch and trunk of woody plants; the inflammation formed at the base of the branch is caused by annually overlapping trunk tissue. The shape of the branch collar is due to two separate growth patterns, initially the branch grows basipetally, followed by seasonal trunk growth which envelops the branch.
Living sculpture is any type of sculpture that is created with living, growing grasses, vines, plants or trees. It can be functional and/or ornamental. There are several different types of living sculpture techniques, including topiary, sod works, tree shaping and mowing and crop art. Most living sculpture technique requires horticultural skills, such as grafting or pruning, to create the art.
Richard C. Reames is an American artist, arborsculptor, nurseryman, writer, and public speaker. He lives and works in Williams, Oregon.
Arthur Wiechula was a German landscape engineer. His marriage to Lydia Lindnau, produced three children, Margarethe (1895), Max (1897) and Ernst (1900).
Bonsai cultivation and care involves the long-term cultivation of small trees in containers, called bonsai in the Japanese tradition of this art form. Similar practices exist in other Japanese art forms and in other cultures, including saikei (Japanese), penjing (Chinese), and hòn non bộ (Vietnamese). Trees are difficult to cultivate in containers, which restrict root growth, nutrition uptake, and resources for transpiration. In addition to the root constraints of containers, bonsai trunks, branches, and foliage are extensively shaped and manipulated to meet aesthetic goals. Specialized tools and techniques are used to protect the health and vigor of the subject tree. Over time, the artistic manipulation of small trees in containers has led to a number of cultivation and care approaches that successfully meet the practical and the artistic requirements of bonsai and similar traditions.
Inga alley cropping is the planting agricultural crops between rows of Inga trees. It has been promoted by Mike Hands.
Christopher Cattle is a British furniture designer who has developed a process of growing furniture by shaping living trees. Cattle calls his work GrownUp Furniture but it is also known as Grown Furniture.
Full Grown is a UK company that grows trees into chairs, sculptures, lamps, mirror frames and tables. It was co-founded by Gavin Munro in 2005.
In the Western history of gardening, from the 16th to early 19th centuries, a wilderness was a highly artificial and formalized type of woodland, forming a section of a large garden. Though examples varied greatly, a typical English style was a number of geometrically-arranged compartments closed round by hedges, each compartment planted inside with relatively small trees. Between the compartments there were wide walkways or "alleys", usually of grass, sometimes of gravel. The wilderness provided shade in hot weather, and relative privacy. Though often said by garden writers at the time to be intended for meditation and reading, the wilderness was much used for walking, and often flirtation. There were few if any flowers, but there might be statues, and some seating, especially in garden rooms or salle vertes, clearings left empty. Some had other features, such as a garden maze.
There are various methods of tree shaping. There are strengths and weaknesses to each method as well commendable tree species for each process. Some of these processes are still experimental, whereas others are still in the research stage. These methods use a variety of horticultural and arboricultural techniques to achieve an intended design. Chairs, tables, living spaces and art may be shaped from growing trees. Some techniques used are unique to a particular practice, whereas other techniques are common to all, though the implementation may be for different reasons. These methods usually start with an idea of the intended outcome. Some practitioners start with detailed drawings or designs. Other artists start with what the tree already has. Each method has various levels of involvement from the tree shaper.
