Crown Reduction & Shaping

Tree reduction and shaping is a method in which the crown is decreased in size. This should be tackled so that the tree maintains its natural form, with substantial, healthy growth points. The most fundimental part of any tree target pruning is the finishing/pruning cut!

Occassionally trees need to be manipulated (shaped) to promote a well-balanced crown, this should be achieved without mutilating the trees natural form.

 

How does tree reduction benefit us?

 

- It is an effective way of maintaining a healthy tree and encorages beneficial re-growth.

- It can temporarily resolve sunlight issues, however, be aware that once the tree puts on re-growth the crown will become denser.

- It decreases the end-weight of main scaffold branch work, reducing the risk of limb failure/loss.

- It decreases the 'sail effect' upon the tree and its root system, preventing tree failure.

 

The optimum percentage that should be removed from branch length (reduced) is 30%, however, this measurement will normally be specified in metric terms.

Crown Thinning

Crown thinning is a method in which the crown density is decreased by removing selected small diameter branch work. Thinning operations target mainly the interior growth (centeral 1/3), but can be focused on the extremities if necassery. Thinning specifications are usually provided as a percentage removed.

 

What are the benefits of crown thinnning?

 

- It is the most effective way of resolving sunlight issues, as it allows dappled light to pass through the crown. With little re-growth developing from the pruning cuts, the crown density remains low, unlike the response from a crown reduction.

- It decreases the 'sail effect' upon the tree and its root system, preventing tree failure.

- Most trees benefit from increased air circulation within the crown, Apple trees being a good example of this.

 

It is important that trees are not over thinned as this may lead to an increased risk of disease, and potential limb failure, as remaining limbs are left exposed (Lions tailing).

 

Crown Lifting

Crown lifting is the method used to remove of selected lateral branches from the lower part of the crown, meaning that the overall height of the crown is lifted.

 

The benefits:



- Convenient method for use around driveways and property, creating more suitable access around the trees vicinity.

- Public highways and footpaths have legal specifications for height clearence from trees.

- Can be used to clear telephone and power lines.

- Prevents a nasty bump on the head!



Deadwood & Hazardous Limb Removal

Year in year out a trees growth continues, from a young sapling through to maturity and even into their veteran stages. During this life cycle cativites and wounds are imminent, with deadwood forming and die-back occuring at furthest extremities. As a tree reaches the veteran stages of its lifespan, limb failure will occur as it begins to 'grow down'. Trees can also become hazardous due to storm damage, pests and diseases. It is for these reasons that it may be necessary to remove hazardous/ dead branches and limbs, especially in areas used frequently by members of the public.

 

We are equiped to take care of these situations by removing hazardous branch work and undertaking visual tree inspections, checking for further potential weaknesses or hazards within the tree.

 

However, deadwood does have its benefits, it creates the perfect habitat for native birds, insects and animals. So, its best only to have it removed if absolutely necessary.

 

All tree pruning operations are carried out in accordance with the guidlines set out in BS 3998:2010.
