Tree pruning in Auckland services. Regular tree pruning will help keep your tree healthy and safe. The amount of live tissue that can be removed in one growing season depends on the tree size, species, age, and the pruning objectives.
Younger trees tolerate the removal of a higher percentage of living tissue than mature trees. An important principle to remember is that a tree can recover from several small pruning wounds faster than from one large wound.
A common mistake is to remove too much inner foliage and small branches. It is important to maintain an even distribution of foliage along large limbs and in the lower portion of the crown. Over-thinning reduces the tree’s sugar production capacity and can create tip-heavy limbs that are prone to failure.
Mature trees should require little routine pruning. A widely accepted rule of thumb is never to remove more than one quarter of a tree’s leaf-bearing crown. In the case of mature trees, pruning even that much could have negative effects.
Removing a single large-diameter limb can sometimes create a wound that the mature tree may not be able to close. The older and larger a tree becomes, the less energy it has in reserve to close wounds and defend against decay or insect attacks. The pruning of large mature trees is usually limited to the removal of dead or potentially hazardous limbs.
Tree pruning in Auckland Techniques for mature trees
Specific types of tree pruning may be necessary to maintain a mature tree in a healthy, safe, and attractive condition. We have listed some of the more common tree pruning techniques below.
Dead wooding is the removal of dead, dying, diseased, crowded, weakly attached and low-vigour branches from the crown of a tree.
Crown care tree pruning of branches (3-5 cm) and fine branches (1-3 cm) is essential to prevent poor crown development (e.g. co-dominants). Dead, dying, diseased, crossed and rubbing branches are to be removed. When determining the clearances for trees in traffic areas, considerations must be made for the site requirements and the effect of pruning on the surrounding areas.
If necessary, the respective pruning measures are to be carried out. If necessary, branch stubs are to be removed.
Raising/lifting tree pruning entails the removal of the lower branches from a tree in order to provide clearance for buildings, vehicles, pedestrians, and vistas.
Crown reduction tree pruning is used to reduce either the height of a tree or its lateral extension in accordance with the safety requirements and the surrounding tree environment. Where necessary the work will be carried out using arboricultural rigging techniques to prevent any property damage. The tree will retain a natural and aesthetically pleasing form.
