Top 5 tree pruning operations

Tree pruning operations can vary depending on several factors, i.e species, height, width, age & proximity to buildings.  Listed below is the most commonly used tree pruning operations.

1. Crown clearing

Crown cleaning is the removal of dead, dying, diseased, crowded, weakly attached and low-vigor branches from the crown of a tree.

2. Crown thinning

Tree thinningCrown thinning is the selective removal of branches to increase light penetration and air movement through the crown.Thinning opens the foliage of a tree and reduces weight on heavy limbs, without compromising the tree’s natural shape.

3. Crown lifting

Tree crowningCrown lifting removes the lower branches from a tree in order to provide clearance for buildings, vehicles, pedestrians and vistas.

4. Crown reduction

Crown  reduction reduces the size of a tree, often for clearance for utility lines.  Reducing the height or spread of a tree is best accomplished by pruning back the leaders and branch terminals to lateral branches that are large enough to assume the terminal roles (at least one-third the diameter of the cut stem).  Compared to topping, this helps maintain the form and structural integrity of the tree.

5. Pollarding

Pollarding involves removing a percentage (normally between 25% and 40%) of  the crown of a semi-mature tree. The re-growth is then removed at  regular intervals to restrict both the height and spread of the tree.
