Hedgerow trees

Hedgerow trees are trees that grow in hedgerows but have been allowed to reach their full height and width. There are thought to be around 1.8 million hedgerow trees in Britain (counting only those whose canopies do not touch others) with perhaps 98% of these being in England and Wales. Hedgerow trees are both an important part of the English landscape and valuable habitats for wildlife. Many hedgerow trees are

s. The age structure of British hedgerow trees is old because the number of new trees is not sufficient to replace the number of trees that are lost through age or disease. New trees can be established by planting but it is generally more successful to leave standard trees behind when laying hedges. Trees should be left at no closer than apart and the distances should vary so as to create a more natural landscape. The distance allows the young trees to develop full crowns without competing or producing too much shade. It is suggested that hedgerow trees cause gaps in hedges but it has been found that cutting some lower branches off lets sufficient light through to the hedge below to allow it to grow.


Importance of hedgerows

Hedges are recognised as part of a cultural heritage and historical record and for their great value to wildlife and the landscape. Increasingly, they are valued too for the major role they have to play in preventing soil loss and reducing pollution, and for their potential to regulate water supply and to reduce flooding. There is increased

Max Hooper published his original formula in the book ''Hedges'' in 1974. This method is only a rule of thumb, and can be off by a couple of centuries; it should always be backed up by documentary evidence, if possible, and take into account other factors. Caveats include the fact that planted hedgerows, hedgerows with

Hedge laying

If hedges are not maintained and trimmed regularly, gaps tend to form at the base over many years. In essence, hedgelaying consists of cutting most of the way through the stem of each plant near the base, bending it over and interweaving or

it between wooden stakes. This also encourages new growth from the base of each plant. Originally, the main purpose of hedgelaying was to ensure the hedge remained stock-proof. Some side branches were also removed and used as firewood. The maintenance and laying of hedges to form an impenetrable barrier for farm animals is a skilled art. In Britain there are many local hedgelaying traditions, each with a distinct style. Hedges are still being laid today not only for aesthetic and functional purposes but also for their ecological role in helping

. The height of the cutting can be increased a little every year. Trimming a hedge helps to promote bushy growth. If a flail cutter is used, then the flail must be kept sharp to ensure that the cutting is effective on the hedge. The disadvantage of this is that the hedge species takes a number of years before it will flower again and subsequently bear fruit for wildlife and people. If the hedge is trimmed repeatedly at the same height, a 'hard knuckle' will start to form at that height – similar to the shape of a

ranging from 1 to 10. '1' describes the action to take for a heavily over trimmed hedge, '5' is a healthy dense hedgerow more than 2 metres in height, and '10' is a hedge that has not been managed at all and has become a line of trees. The RSPB suggest that hedges in Britain not be cut between March and August. This is to protect nesting birds, which are protected by law.Tackling Hedges

Types


Instant hedge

The term ''instant hedge'' has become known since early this century for hedging plants that are planted collectively in such a way as to form a mature hedge from the moment they are planted together, with a height of at least 1.2 metres. They are usually created from hedging elements or individual plants which means very few are actually hedges from the start, as the plants need time to grow and entwine to form a real hedge. An example of an instant hedge can be seen at the

Estate in East Anglia, where fields of hedges can be seen growing in cultivated rows, since 1998. The development of this type of mature hedge has led to such products being specified by landscape architects, garden designers, property developers, insurance companies, sports clubs, schools and local councils, as well as many private home owners. Demand has also increased from planning authorities in specifying to developers that mature hedges are planted rather than just whips (a slender, unbranched shoot or plant). A 'real' instant hedge could be defined as having a managed root growth system allowing the hedge to be sold with a continuous rootstrips (rather than individual plants) which then enables year-round planting. During its circa 8-year production time, all stock should be irrigated, clipped and treated with controlled-release nutrients to optimise health.


Quickset hedge

A quickset hedge is a type of hedge created by planting live whitethorn (common hawthorn) cuttings directly into the earth (hazel does not sprout from cuttings). Once planted, these cuttings root and form new plants, creating a dense barrier. The technique is ancient, and the term ''quickset hedge'' is first recorded in 1484. The word ''quick'' in the name refers to the fact that the cuttings are living (as in " the quick and the dead"), and not to the speed at which the hedge grows, although it will establish quite rapidly. An alternative meaning of quickset hedging is any hedge formed of living plants or of living plants combined with a fence. The technique of quicksetting can also be used for many other shrubs and trees.

Cornish hedge

A Cornish hedge is an earth bank with stones. It normally consists of large stone blocks constructed either side of a narrow earth bank, and held in place with interlocking stones. The neat rows of square stones at the top are called "edgers". The top of the hedge is planted with grass turf. Sometimes hedging plants or trees are planted on the hedge to increase its

ing height. A rich flora develops over the lifespan of a Cornish hedge. The Cornish hedge contributes to the distinctive field-pattern of the Cornish landscape and its semi-natural wildlife habitat. There are about of hedges in Cornwall today. Hedges suffer from the effects of tree roots, burrowing rabbits, rain, wind, farm animals and people. How often repairs are needed depends on how well the hedge was built, its stone, and what has happened to it since it was last repaired. Typically a hedge needs a cycle of repair every 150 years or so, or less often if it is fenced. Building new hedges, and repairing existing hedges, is a skilled craft, and there are professional hedgers in Cornwall. The Cornish Hedge Research and Education Group (CHREG) supports the development of traditional skills and works with

Regulation

In the US, some local jurisdictions may strictly regulate the placement or height of a hedge, such as the case where a Palo Alto city resident was arrested for allowing her xylosma hedge to grow above two feet. In the UK the owner of a large hedge that is adversely affecting the reasonable enjoyment of neighbouring domestic property can be made to reduce it in height. In England and Wales, high hedges are covered under

. For a hedge to qualify for reduction, it must be made up wholly or mainly of a line of two or more evergreen or semi-evergreen trees or shrubs and be over 2 metres high. To some degree, it must be a barrier to light or access. It must be adversely affecting the complainant's reasonable enjoyment of their domestic property (either their house or garden) because of its height. Later legislation with similar effect was introduced in Northern Ireland, Isle of Man and Scotland.
