Taking care of trees is not just about watering, pruning or fertilising. Understanding different levels of arborists and their specialities can save you time, money, and worry. In this guide, we’ll help you navigate the world of tree care professionals, focusing on how to choose the right arborist for expert tree care that keeps your garden thriving.Â
Choose Based on Specialties
Â
Arborists bring a range of skills depending on their area of focus. Tree surgeons specialise in the hands-on work of pruning, removing, and maintaining trees safely. Their expertise lies in managing the physical health and structure of trees. Landscape architects, on the other hand, blend tree knowledge with garden design, ensuring trees fit beautifully and sustainably into outdoor spaces. Horticulturists focus on plant health and soil management, offering advice on tree nutrition and disease prevention. Knowing these differences helps you select an expert suited to your particular tree care needs, whether it’s improving your garden’s look or addressing tree health concerns.
Â
Understanding Arborist Levels
Â
In Australia, arborists are classified by levels that reflect their training and responsibilities. These levels help you understand the depth of expertise an arborist brings, and they are referred to as Australian Qualification Framework (AQF) Level 3, and AQF Level 5, or Certificate 5.
Â
A Level 3 Arborist is an Arborist who has achieved certification by completing an apprenticeship with classroom and practical field-based learning. A Level 3 Arborist is a fully-qualified tradesman. You can use them for all pruning and tree removal tasks.Â
Â
A Level 5 Arborist has completed advanced studies in arboriculture, earning a higher qualification that sets them apart as an expert in the field. They can perform all the tasks of a Level 3 Arborist and offer more specialised services. These include complex health assessments of trees, providing detailed written arboricultural reports for local councils, and advising developers on how to minimise environmental impact during construction. They can also diagnose specific issues, such as nitrogen deficiency, and recommend targeted treatments like tree injections, soil decompaction, or fertilisation.
Â
If you have a protected tree or are involved in a tree-related dispute with neighbours, a Level 5 Arborist can offer thorough, well-informed solutions. In some cases, councils may require their presence onsite during tree work to supervise and ensure that the highest standards are maintained throughout the project.
Â
Key Selection Criteria
Â
When choosing an arborist, qualifications are crucial. They must have completed Certificate III in Arboriculture to be compliant for the work. You can check for certifications such as membership in the International Society of Arboriculture (ISA) or recognised Australian qualifications. These credentials confirm their training and adherence to industry standards.
Â
Experience matters as well. Find how many years of experience they have from their website. Positive reviews and references can provide confidence in their work quality.
Â
Good communication is essential. The right arborist will explain their approach clearly, listen to your concerns, and provide transparent quotes. Avoid those who pressure you into quick decisions or lack proper documentation.
Â
Price should reflect the quality of service. Obtain multiple quotes and be cautious of prices that seem too low, which may indicate poor workmanship.
Â
Safety and insurance must not be overlooked. Confirm that the arborist follows Australian Standard AS4373 for pruning and holds valid insurance to protect both you and their team.
