​

Shigo’s famous touching trees workshop has been given a new lease of life by Mark Hartley Australia’s renowned subject matter expert.

​

You can expect a sleeve rolled up, hands-on laboratory exploration about how trees work. It’s a once in a lifetime workshop that you won’t forget and will be one of the most important investments you will make in your continuing education.

​

You will develop a three-dimensional cellular understanding of trees that many arborists lack. You will gain the skills to prepare samples and leave with practical exercises you can use on your own and with others.

​

If you diagnose tree problems, assess development impacts on trees and/or prune trees, understanding their inner workings will help you to make better decisions.

By dissecting and examining samples and using prepared slides, you will:

• find and identify many of the common cells found in trees

• gain a better understanding of roots and how they work

• develop an understanding of how xylem functions in 3 different planes

• discover how CODIT really works

• observe how vessels interact around the branch collar and how this influences how we prune.

• touch and examine unusual and specially selected samples

• get intimate with trees like you never have before”

​

What to bring: 

​

• Enclosed footwear – we will be using sharp and heavy items

• You may get dirty, so we recommend clothes that you are happy to get dirty

• Long hair should be tied back

• On the last day, we will be using food colouring and
