Tree Pruning

Pruning a tree involves removing specific branches or stems. Pruning benefits all aspects of the tree’s health and well-being and prolongs the lifespan of the tree.

Such treatment includes the removal of dead, damaged and diseased branches to help aid the prevention of insect & decay organisms from entering the tree; which can eventually lead to fatal implications towards the tree's health.

Dead-Wooding

“Dead wooding” is the removal of all dead, dying or diseased branch wood, including broken branches or stubs left from previous poor tree surgery operations, found within the crown of the tree.

Dead wood is cut back to a suitable live and healthy branch or junction at the bark ridgeline or to a point where callous growth can properly be formed.

Crown Thinning

“Crown Thinning” is the careful and systematic removal of branches from within the crown to reduce its density between usually 10-50%.

Leaving a well-balanced tree with even growth throughout the canopy. Thus, allowing more air and light to pass through the tree.

Pollarding

“Pollarding” is the removal of all the growth of a tree back to the main stem. Objectively making the tree produce a quantity of vigorous shoots from the framework, and pruning the new growth back once every 3-4 years on a cyclical basis.

Pollarding is normally undertaken to broadleaf species such as Lime, Poplar, Plane, Willow. The aim of pollarding is to create a “Knuckle” where branches will grow out from, thus making the management of the tree systematic and easy to maintain.

Crown Lifting

“Crown Lifting” consists of the removal of the lower branches from the main stem, effectively lifting the height of the trees canopy from the bottom-up to a specified height.

Most clients crown lift to make way for pedestrian walkways, vehicles or just simply to be able to see further down the garden, creating a safer, more enjoyable space.

Crown Reduction & Reshaping

“Crown Reduction” is one of the most popular forms of tree pruning. A Crown reduction is the removal/cutting back of the outer branches, reducing the overall height and spread, by a specific percentage.

Reducing and reshaping the crown alleviates stress and can allow tree to be appreciated from within a confined space, making the tree more suitable to its surrounding.
