Learn to be an Arborist with this distance education course:
- Learn the horticultural skills needed to identify and manage trees
- Learn the management skills needed to manage an arboricultural enterprise
- Get a job, start a business or further your career prospects in the Arboricultural Industry
The arboriculture industry is concerned with the culture of trees - from selection and planting to all of the many tasks involved in facilitating growth and good health. This course builds both skills in management and arboriculture, and is designed to provide a sound foundation to support a career at a supervisory or management level in industry sectors including parks and gardens, residential or commercial tree maintenance/management, land rehabilitation, forestry, etc.

What is Involved in Pruning Large Trees?
Tree pruning is an important aspect of arboriculture. Pruning involves the selective removal of plant material – usually branches in the case of tree surgery. Different types of pruning are used at different times in a tree’s life. Formative pruning is used to shape young plants so that they will grow into healthy, attractive and sound trees. As a tree matures, other types of pruning operations are needed to preserve its health and stability. These operations include branch removal, crown cleaning, crown thinning, crown reduction, crown lifting and crown renewal.
It is also important for arborists to know how to remove a tree safely. Removal of trees should always be viewed as a last resort; however this may sometimes be necessary to prevent trees falling onto houses, cars or causing other dangerous situations.
Tree pruning and tree removal are dangerous operations. We provide the following information as a broad guide to these important arboriculture techniques. However, it is essential to gain first-hand practical experience under the supervision of an expert arborist and to follow all recommended safety measures when carrying out dangerous tree work.
Sometimes branches need to be removed or repaired for the following reasons:
- safety reasons
- obstructing views
- obstructing traffic or crowding overhead wires
If the ground below is free of obstructions, lightweight branches or branch sections can simply be thrown down. For heavier branches or if obstructions prevent clear throwing, ropes are used to lower the cut limbs. This involves passing a strong lowering rope through an anchoring point and then tying the rope to the branch that is to be removed. Ground staff then wraps the rope around the trunk to create friction, which allows the branch to be lowered in a controlled manner.
Dead, damaged, diseased or crowded branches are removed to improve the tree’s appearance and growth. Untidy or nuisance growth such as invasive climbers or messy fruits may also be removed
This involves reducing the density of branches and stems without reducing the overall height or width of the tree. Thinning the crow improves air circulation (and reduces the incidence of disease) and allows more light into the tree and onto the ground below.
Crown thinning is usually carried out on mature deciduous trees; it may also be used to compensate for root loss or root damage on newly-transplanted trees or following excavations. Generally the crown is reduced by a maximum of 25%. Excessive thinning can result in sunburn and stimulation of weak, epicormic shoots. It can also lead to an overall decline in the tree’s vigour.
This involves cutting back branches to reduce the tree’s size (ie. reducing its height and/or canopy spread). It is usually carried out because the tree has become too large its position.
Branches are cut back to growing points (laterals) so that the overall shape and vigour is maintained. They are not lopped back to the trunk – re-growth from these cuts is usually weak, overcrowded and unattractive.
This involves pruning the lower limbs so that the height of the crown in raised, allowing better access and light penetration below.
Ideally lower branches are removed while the tree is still growing, reducing the need for large, potentially disfiguring cuts.
This involves renewing a damaged or severely lopped crown. It is carried out to improve the tree’s appearance and vigour.
Crown renewal is generally a long-term process, often taking several years of corrective pruning and crown thinning before the desired shape is realised.
