Crown Reduction
This process makes the overall size of the tree smaller to allow light and wind to pass around and through the crown. The tree is always pruned back to growth points, where possible, to allow the tree to continue its life growing in a healthy balanced form
Crown Thinning
Often a tree blocks light when the crown becomes too dense, hence the need to thin. This process removes the small internal stems to allow filtered light through and also reduces the wind resistance to avoid potential failure (limbs breaking) in high winds.
Crown Lifting
Another way to allow light in is to raise the crown of the tree to an appropriate height that also compliments the balance of the tree. It can also open up views and clear branches away from buildings. Crown lifting is a good way to allow light into the garden/area without felling the tree.
Pollarding
This process removes all of the crown either back to the original growth points or to a specific height. Certain species react well to this, for example Willows, Limes and Plane trees in cities. This should be done on a regular cycle, depending upon species and circumstances.
Dead Wooding/Crown Cleaning
The removal of dead branches is necessary for safety reasons and also for aesthetics. It is often combined with a crown clean, which removes dead wood, crossing and damaged branches. A crown clean will increase the amenity value and promote a healthier canopy.
Hedge trimming
Hedges require annual maintenance at least once, depending upon the species, allowing them to grow dense foliage. Hedges can be reduced in height and brought down to a more manageable level.
