Trees are the forgotten giants of our gardens because stature-wise they are often out of sight, and therefore out of mind. However, trees can cause significant problems compared to other plants, simply because of their bulk (especially if they fall over!). That’s why arboriculture – the science of how trees grow and respond to their environment – is so valuable. This course is ideal for gardeners, farmers, horticulturalists, arborists or those who simply love trees!
The Certificate of Arboricultureis an online program that will teach you thetechniques and practices used to cultivate healthy trees as well as diagnose and treat tree disorders.
In this professional development course, you will learn about tree biology, arboricultural equipment, planting techniques, tolerant plant species, and how to establish a tree plantation.
You will also study how to prune and fell trees, diagnose and control tree problems including soil issues, strengthen weak trees and perform tree surgery safely.
On completion of this course, you will know how to care for and nurture a variety of tree types, which will give you the confidence to extend your tree-loving career or even plant your own tree plantation!

When you study with Australian Online Courses, you will be assessed using a competency-based training method.
Competency-based training focuses on the achievement of skills and knowledge against set criteria to meet industry-standard and is not benchmarked against other students’ work.
In this course, the assessment will be comprised of written assignments and exercises, which may include short answer questions, reports, essays, research projects and reflective tasks.
If you do not achieve a competency result on your first attempt, you have two more attempts to pass your assessment. So, you have three attempts in total to obtain a competency result.
In this way, you can complete your course in your own time and at your own pace with the assistance of unlimited tutor support.
