‘Arboriculture’ is the cultivation and care of trees for amenity purposes. Arborists are the professionals who practise arboriculture, improving the quality of our lives by properly selecting, planting and caring for trees that enrich our environment and improve the air we breathe.
The team at Greenacre Trees and Landscapes are all experienced and qualified Arborists. We are very passionate about trees and the environment which is evident in the quality of our work and in the amount of repeat business and customer referrals we have.
All of our work is carried out to British Standard BS3998:2010.
Greenacre offer a full range of professional arboricultural services and techniques.
Tree pruning is particularly important in urban environments where trees, buildings and roads need to co-exist. With trees and buildings sharing valuable space maintaining urban trees on a regular basis is necessary otherwise trees simply out-grow the spaces they are in or cause a nuisance to tree owners and their neighbours.
Greenacre undertake all types of tree and shrub pruning no matter how small or large your tree. We are very good at transforming even the most untidy and unruly tree into something attractive and pleasing to look at.
There are essentially three main types of tree pruning; crown reduction, crown lifting and crown thinning.
Tree Pruning - Crown Reduction and Shaping
Do you need more light in your house or garden? Or is your tree getting too big?
A crown reduction will reduce height and spread of the overall crown of a tree.
The ends of the branches are removed therefore reducing the outer canopy of the tree. A crown reduction can also be carried out to improve or maintain the shape of a trees crown and/or help balance an uneven crown especially if tree has been damaged or if large diseased limbs have needed to been removed.
Tree Pruning - Crown Lifting
Are the lower branches of your tree getting in the way?
A crown lift is the trimming or pruning of the lower branches of a trees crown. The aim of this process is to increase light and also enable access under the canopy of the tree. We frequently carry out this type of pruning where branches and tree foliage is drooping down over highways, footpaths and driveways, or in gardens where people would like to sit under their trees or access underneath them with a mower.
Tree Pruning - Crown Thinning and Deadwood Removal
Crown thinning is the removal of a portion of smaller/tertiary branches, usually at the outer crown, to produce a uniform density of foliage around an evenly spaced branch structure. It is usually confined to broad-leaved species. Crown thinning does not alter the overall size or shape of the tree
Deadwooding – as trees mature they naturally produce deadwood. The removal of deadwood from a tree crown is mainly for safety reasons but will also improve the way the tree looks. The process involves the safe removal of dead, dying and diseased branches throughout the crown of a tree making the area below the tree safe from falling debris. Other vegetation can also be removed at the same time, such as ivy and other climbers.
The purpose of formative pruning is to assist the young tree to develop into a stronger and well-shaped tree. The structure of the tree can be greatly improved by selective branch removal. This ensures strong branch attachments and a good crown structure.
When Should Tree Pruning be Done?
This very much depends on the type of tree. Most deciduous trees (ones that lose their leaves) are best pruned in the autumn and winter. Trees are dormant at this time and tree work is less stressful for them. Conifers can be trimmed all year round but you must beware of nesting birds particularly in conifer. Due to the natural density of conifer trees they lend themselves to a perfect nesting host. The official bird nesting season is from the 1st of March until the end of September. Any nesting bird is protected by law within these dates so this means that our work can not impact a nest during these times but does not mean work can not be carried out else where in the tree.
There are exceptions, especially in flowering or stone fruiting trees, such as flowering cherry trees these should be pruned in late summer. Some trees are susceptible to Silver Leaf a fungal disease carried in the wind; these are best pruned in late summer. Light pruning work can be carried out on many trees however we would only recommend carrying any major pruning works in the Autumn.
A few conifers including Yew and Thuja (although not as reliable as Yew) can be pruned hard as they will grow from old wood. Most conifers will not grow back from old wood therefore only being able to be pruned back to the green foliage only. Conifers can be pruned from spring to late summer. Avoid trimming in exceptionally cold conditions where there is likelihood of snow fall or frost as this can cause scorching.
Fruit trees generally are pruned in the winter except for trees bearing stone fruit. Apple & pear trees should be pruned December or January after the crop has finished and has been picked or fallen from the tree.
Trees and the Wind
The weather in the UK is changing. We are experiencing higher winds into the spring and early summer now. Why should this matter? As trees are in leaf at this time it increases the sail effect of a trees canopy. The additional force of the wind on the trees limbs puts the tree’s structure under increased stress and therefore if there are weakness, deadwood or disease this can lead to failure, falling branches and damage to the tree.
Felling and Sectional Dismantling
Arborists do not like felling trees however circumstances often require their removal.
Whatever the size of tree or its location contact Greenacre Trees for expert and experienced advice on the safe and efficient removal of your tree. Generally, due to trees being located near buildings and other hazards, there is not room for a tree to be felled as a whole tree.
Most trees are dismantled a section at a time, in a controlled manner. The tree is climbed by an experienced and qualified Arborist wearing a harness and specialist rigging equipment. The climber always works have a ground team. The tree is dismantled, first removing the outer part of the crown until there are just the main limbs left. After each cut the timber is lowered to the ground team on rope, using expert rigging techniques. Finally the main limbs and trunk are removed in sections which are lowered to the ground also.
Greenacre are particularly good at working in confined spaces, spaces with multiple hazards and undertaking complex tree dismantling.
We can also remove tree stumps, ask us about our stump grinding service using our specialist stump grinder. Customers often want to replant, lay turf or a driveway where a tree once was and stump grinding is the best way of removing those unwanted stumps.
Removal of Dangerous Trees
Sometimes trees are too structurally unsound to be climbed.
In these instances a hydraulic platform or crane is used. When Greenacre visit a customer and their tree on site, the health and condition of the tree is assessed and the most suitable and safest method of work is established. Greenacre are experienced in the use of both platforms and cranes, and will select the best machine for the job, taking into consideration access and the height and outreach required.
Pollarding is a method of pruning to manipulate the size of a tree, generally to prevent trees and shrubs outgrowing their allotted space. The branches of the tree are cut back to the main stem of the tree. Limes and London Plane trees are often pollarded along streets and pavements to reduce their size in urban locations. They are recognised by their appearance in having a multiple of stems on a single trunk.
Pollarding is an intense form of tree management usually first carried out on younger trees which will then require regular re-pollarding of the crown when it re-grows. Not all trees are suitable for pollarding and only deciduous trees can be pollared. Pollarding was first introduced as a way managing trees for firewood production. Pollarding works as the same principle as copping but allowing more multiple growth to form from the multiple branches rather than copping which produces growth from a single stump. This also allowed the new growth to form high up away from hungry deer.
Coppicing is a pruning technique where a tree or shrub is cut to near ground level in early spring (before bud break) to encourage vigorous young shoots, usually done from the second year after planting. Pollarding is similar, but stems are pruned to a higher point on a trunk or ‘leg’. Both techniques allow gardeners to grow trees and shrubs that would be too large left unpruned.
Mature and Veteran Trees
Mature and veteran trees require specialist and different management techniques compared to that of younger trees. Mature and veteran trees are very special, they are a legacy left from previous generations and we are passionate about preserving these magnificent specimens for future generations to appreciate.
