Tree Pruning

There are various types of tree pruning operations which have a certain purpose and desired outcome in tree maintenance operations and may be the answer to many of your questions and problems, these are:

  • Crown reductions
  • Crown lifting/ raising
  • Crown thinning

Crown Reductions

This involves pruning the height and spread of a tree and can be a useful pruning method in restricted areas e.g. between two properties. The benefits include:

  • Retaining the natural shape of a tree.
  • Increases light.
  • Reduces likelihood of nearby damage to buildings and property.

Crown lift/raising

This involves removing lower branches to have a desired outcome which include:

  • Creates space, and makes your garden look bigger.
  • Enabling clear sight along roads and streets.
  • Clearing paths, parkland and car parks. Overhanging branches can cause safety issues for pedestrians and cars. Crown raising keeps the lowest branches well away from the people and cars below.
  • Reduces likelihood of nearby damage to buildings, and property.

 

Crown thinning

With crown thinning you selectively remove smaller inner branches within the inner canopy of a tree, but still retain the overall shape. Benefits include:

  • Lets more light into an area.
  • Trees can go through immense strain in storms and heavy winds, and a dense crown only makes things worse. Crown thinning can help alleviate this pressure by allowing the flow of air throughout the canopy, which may prevent, or lower the risk of branch and tree failure and ultimately damage to property.
  • Aesthetically gives the tree an airier more balanced feel to it.

 

 

Dead wooding

Trees can contain dead and dying branches which can create health and safety risks, and can also damage property, by removing the deadwood you eliminate this problem.

 

Bad arboriculture practice

 

Topping

Topping is generally used to reduce the tree height and size significantly, although this may work in the short term, it is not recommended as you should generally not remove any more than 30 percent of a trees crown. The tree will grow back rapidly to replace its missing leaf area, to try meet the nutritional requirements of the tree. This will create many weak growth unions which can be hazardous to nearby property and can pose a risk to health and safety.

Topping will affect the tree in four main ways which include:

  1. Opens the tree up to fungal pathogens and rot, making large limbs dangerous.
  2. The tree’s leaves manufacture its food.Repeated removal literally starves the tree.This makes it susceptible to secondary fungal diseases such as various forms of root rot a common cause of failing trees.
  3. New limbs made from the sucker or shoot regrowth are weakly attached and break easily in wind.A regrown limb never has the structural integrity of the original.
  4. The thick regrowth of suckers as a result of topping make the tree top-heavy and more likely to catch the wind.This increases the chance of blow-down in a storm.
