Trees Are Sunlight Traps

Any voids in a tree’s canopy will be filled with branches and leaves (they are phototrophic – light-loving – growing towards the light). According to the available area, the soil they grow on, the weather, the available water, and other factors, they also evolve in harmony with their surroundings. A tree is a type of woody plant with Plants that have evolved a strategy to grow upward in order to absorb as much sunlight as possible include trees. The tree stores sugars throughout its structure, but primarily in the roots, after the leaves convert sunlight into sugars.

This fundamental objective, to block out as much sunlight as possible, might occasionally be directly at odds with how nearby humans use the land. By virtue of their very nature, trees shed shade, lose leaves, and extend their branches in quest of light. Tree surgeons with experience and expertise can contribute to reducing such tension and enhancing the safety of the neighbours’ residents and property.

Tree Wisdom

Different tree species respond to trimming in various ways. We can provide customers with accurate advice to help them avoid future difficulties and, more significantly, not really cause future problems thanks to the knowledge we’ve acquired over the years of climbing and cutting trees.

The right way to prune a tree or the choice to remove it entirely must be based on a variety of variables, including the tree’s species, location, health (or lack thereof), proximity to other trees, previous tree surgery, season, and, most importantly, what you, the customer, hope to achieve in the short and long terms.

The one thing that many clients do not want is additional shade and leaves, which is sometimes the result of poor, heavy-handed tree surgery on some species.

Practical Tree Care

Contrary to our name and ideology, we do not oppose cutting down trees or their entire removal when necessary. We understand that trees have a lifetime in urban settings or next to roads and pathways. Trees have a purpose, a job, and a usage in urban environments. They need to be removed effectively and safely when they grow too big, get sick, or become harmful.

What Is Tree Surgery?

One specialty within the broader field of arboriculture is tree surgery.

Care for trees is referred to as arboriculture. A person who is qualified and able to perform tree surgery is known as an arborist.
Tree surgery involves shaping and trimming trees to keep them in the proper place. It is an effort to prolong their lifespan and keep them safe and healthy. In order for them to continue serving as assets for their owners and everyone else who can view them, it is crucial to maintain and possibly even improve their aesthetics.

When performing tree surgery, accessing the tree may require employing a mobile elevated work platform or climbing it using a rope and harness (MEWP). Although hand saws and loppers may be used on smaller trees, chainsaws are frequently employed in this process. The LOLER 1998 – Lifting Operations and Lifting Equipment Regulations apply to all equipment used as part of the climbing equipment.

Tree surgery, in its broadest sense, is the practise of knowing when, when, and how to make cuts into trees. But more crucially, a professional tree surgeon will have a thorough understanding of trees as living things and will know when to leave them alone or, on the other extreme, when they may be dangerous or inappropriate for their location and need to be completely removed.

Performing tree surgery is a profession. There are basic requirements to work with chainsaws, climb, fell, and prune trees lawfully as well as nationally recognised certifications for arborists.

British Standard Recommendations for Tree Work (BS3998:2010)

The British Standards Institution issued this document as guidance for tree surgeons. Since their initial release in the 1960s, there have been two revisions. The first revision was issued in 1989, and the most recent, long-awaited revision was issued on December 31, 2010. In the 21 years since 1989, a lot has changed.

This is a document/procedure issued from the British Standards Institution as a guide for tree surgeons.

There have been 2 revisions since their first issue in the 1960’s. The first revision was in 1989, and this latest, long awaited, revision was issued on 31 December 2010. A lot has changed since in the 21 years since 1989
It recognises the following general tree surgery procedures.

Crown Reduction

This is a tree surgery procedure that results in a reduction in the overall height and spread of a tree. This is accomplished by generally shortening twigs and/or branches while retaining the tree’s main framework.

A Crown Reduction may be performed to reduce the size of a tree that has grown too large for its situation.

To keep a young tree at a manageable size, formatively prune it.

Crown Reduction – The Problems

However, there are some issues with this tree surgery procedure. This should only be considered as a last resort for large and mature trees, and only by arborists with extensive tree work experience. Poor workmanship and heavy-handed reductions can be counterproductive in the long run, resulting in future problems and/or sending the tree into a terminal decline spiral.

Different tree species will tolerate and respond differently to an overall reduction. New branches that form as a result of pruning are inherently weak and prone to decay in some species.

It is possible that a crown reduction is not appropriate due to the age, health, and species of the tree, as well as its location. If some action is unavoidable due to the requirements of its position, complete removal and replacement of the tree should be preferred. Again, only an experienced arborist should make this decision based on all of the facts.

See the Crown Reduction web page for a more in-depth discussion of how and when crown reductions should be performed, the issues that arise when the wrong decisions are made, and the long-term consequences of poor tree surgery.

Crown Thinning

Crown thinning is a tree surgery procedure that removes a certain proportion of the tree’s small, live branches throughout the crown. The crown should be thinned to leave an even density of foliage surrounding a well-spaced and balanced branch structure.

A crown thin should specify the percentage of leaf-bearing branches removed as a percentage of the total. In general, no more than 25-30% of the crop should be removed in a single growing season.

During a crown thinning operation, a good tree surgeon will also remove any dead, dying, crossing, or otherwise defective branches.

Carrying at a Crown Thin may be done for a variety of reasons.

  • Open a canopy to allow more light to enter the area below.
  • Increase the flow of air and light within a fruit tree.
  • Improve a tree’s visual appearance

Crown Lifting

Crown Lifting is a type of tree surgery in which lower branches are pruned or removed to provide a specified vertical clearance.
Carrying at a Crown Lift could be for a variety of reasons.

  • Allow clearance for a walkway or parking space.
  • Increase the sense of openness in a garden or house.
  • Increase the amount of light that enters a home or garden.
  • Creating or improving access for large vehicles along roadways or at site entrances

Crown Lifting – The Problems

When large branches are pruned back to the main stem, the wound created can weaken the structure and increase the likelihood of stem failure. This is especially true when the branch size is comparable to the stem size, or when multiple large branches are removed from the same area, especially if at the same level; for example, on the opposite side of the stem.

The tree is less likely to respond well to wounding if it is mature or old. The tree will be unable to close over the wound, which can lead to extensive decay in the long run.

Different tree species will react differently to wounding.

Selective Pruning

Selective pruning is a type of tree surgery in which only certain branches are pruned, as the name implies. This could be done for a variety of reasons, including

  • To cut or prune branches that are extending over a roof or boundary, for example.
  • Correct the shape of a tree where some branches have over-extended, perhaps on one side.
  • Restore branch structure after improper tree surgery or heavy pruning
  • Creating or improving access for large vehicles along roadways or at site entrances
  • To reshape a tree following storm damage

Deadwood Removal

Deadwood removal is a type of tree surgery in which branches that have died or are dying are removed. The deadwood is frequently removed back to the nearest live wood, and frequently to the point where the tree has naturally separated itself from the deadwood.

  • The purpose of this work could be to remove branches that may eventually fall causing harm or damage
  • Enhance the appearance of a specimen tree aesthetically.
  • Set a standard for future comparisons.
  • Dieback can be tracked.
  • Remove diseased tree parts that could be a source of further infection.


Where there is enough space and no obstacles or targets, a tree can be felled in one felling. The tree is allowed to fall after a directional cut is made at the base of the trunk.

To properly weight the tree, it may be necessary to remove some branches, such as removing a large branch on the opposite side of the intended direction to remove back weight.

A pulling rope or directional winch may be used to encourage the tree to fall in the intended direction when necessary or simply as a failsafe, especially for large heavy trees.

Felling – Things to be aware of

The structural integrity of the wood will be compromised where there is decay in the trunk. The directional cut may not be effective due to a lack of strength.

A tree may have multiple stems and bark in between the stems. When the trunks fall at the base, they may separate and fall in different directions.

Different tree species have varying structural properties and wood fibre strengths. Some tree species can be made to fall away from their natural lean with the right directional cuts. Others, on the other hand, have limited strength and may not be able to. Knowing the difference necessitates practise and knowledge.

Where there is insufficient space to fell a tree in one go, or where there are targets and obstacles that cannot be removed, a tree can only be removed in sections.

Where sections cannot be dropped from the tree, they can be roped down using a pulley block attached to a suitable anchor point in the tree. When sections are heavy and control and security are required, specialised lowering devices are used.

LOLER 1998 – Lifting Operations and Lifting Equipment Regulations must be followed in terms of equipment and operation planning.


Pollard trees have numerous branches that grow from the same height on the trunk. Pollarding begins when a tree is young, usually after it has established itself and has a stem diameter of 25 to 50mm at the desired height. Depending on the situation, 2 to 3 metres.

Pollarding trees is a method of keeping trees at a specific height, which is commonly used in formal settings. Pollards were historically used to mark boundaries and were also used to feed cattle. Fresh leafy growth was allowed to grow out of grazing animals’ reach before being cut and allowed to fall to provide fresh animal feed as needed.

Pollarding may be initiated up to a stem diameter of 200mm depending on the species and knowledge of how well they will respond to this treatment. If this is the case, or if the species is particularly prone to dieback after heavy pruning, lower branches should be kept and phased removed.

Once pollards are established, the only way to maintain them is to re-pollard. This is because re-growing stems will always have relatively weak unions with the trunk. There is no problem when they are small and young, but as they grow, they will become more prone to splitting out. Some species are more powerful than others.


Coppicing is primarily a woodland management technique, but it can also be found and used as an effective tree management tool in a tree surgery / amenity context.

Coppicing is the process of repeatedly cutting a tree down to near ground level and allowing it to regrow on a regular cycle.

The cut stump is known as a coppice stool. Traditionally, this is a method of repeatedly producing straight poles that can be used to make coppice products or as a sustainable method of growing wood for fuel. As a result, a multi-stemmed tree is formed. Once a coppice is established, it must be managed in the same manner as pollarding. If the stems grow too large, they become ‘overstood’ and are more likely to fail in their union with the stool.

Timing of Tree Surgery

Tree surgery operations must be planned in accordance with the season and with due regard for the legal protection afforded to nesting birds and bats.

Complete tree removal is possible at any time of year; however, it may be impossible due to nesting birds or the presence of bats. This is especially true for densely growing species like conifers and trees with a lot of ivy, as well as old trees with nest holes.

Overall Reductions should be avoided in the early spring, just before bud burst and during flowering, and in the early autumn, just before leaf fall. The trees are in a growth phase that makes them particularly vulnerable to pruning at this time. Reductions can be performed in the winter or, ideally, in the summer, when the tree is fully grown and better able to respond to wounding.

Crown thinning can be done at any time of year, but it is best to avoid doing it in early spring, just before bud burst and during flowering, or in early autumn, just before leaf fall, especially if it is a heavy crown thin.

Hedge pruning and hedge reductions, particularly leylandii and laurel hedge reductions, are frequently put on hold during the bird nesting season. Wild birds are legally protected and prefer dense hedgerows. Prior to beginning work, it is nearly impossible to detect wild bird nests. As a result, it is preferable to schedule hedge pruning work outside of nesting season.

Pollarding is traditionally done in the winter, as long as it is not done too late. Pollarding in early spring, when the buds begin to swell, or after the leaves begin to appear, is especially harmful to the tree’s health.

Coppicing, like pollarding, is traditionally done in the winter months, as long as it is not done too late. Pollarding in early spring, when the buds begin to swell, or after the leaves begin to appear, is especially harmful to the tree’s health.

Prunus Species – Trees in the Rosaceae family, particularly those in the genus Prunus, are highly susceptible to Silver leaf, a widespread and common fungal disease (Chondrostereum purpureum). Fungal spores enter the body through wounds, including pruning cuts. It is almost always fatal once established (in Prunus). The time of year when pruning is done is a critical factor in preventing this disease and greatly reduces the risk. They should be pruned in the summer (usually between June and August), when the risk of infection is low.

Plum, cherry, damson, gauge, peach, apricot, and almond are all members of the Prunus genus.

What can happen is also affected by the weather. During periods of heavy rain, clay soils can become compacted in areas around retained trees. Tree work should be rescheduled as much as possible until conditions improve. Climbing beech trees in very cold winter weather can also be hazardous to one’s health and safety because the branches can be brittle
