Professional pruning techniques and the latest research-backed information will be brought together in this dynamic advanced workshop.  Dr. Gilman is one of only a few professionals in the world conducting controlled experiments with trees and their reaction to pruning. He will bring his unique approach to teaching in this one day seminar.  The financial success of your future and the stewardship of our urban forests are directly linked to the art and science of proper pruning. 

Meet Our Speaker:
Dr. Ed Gilman, professor, University of Florida

Dr. Gilman presents preventive arboricultural treatments shown to increase tree health and longevity in compliance with the 2008 edition of the ANSI pruning standards. We will discuss young and old members of our tree population showing how to treat them professionally. Inappropriate reduction, raising the canopy, and other techniques designed to help can often end up initiating a downward health spiral. Above ground treatments for old trees will be discussed in light of recent research and practice. We’ll show you the newest crown pruning and root manipulation research designed to improve tree stability and health. You will learn the latest science-based tree care. Key words include: nursery, root pruning, mechanical stress, aspect ratio, roots, taper, damping, rays, wood, branch orientation, inclusions, intervention, subordination, thinning, and reduction.

AGENDA:

 

Check-In 8:00 AM

 

Morning Session  8:30 AM – 12:00 PM

 

Root System Development Seed to Mature Tree: Creating Stable Architecture
Understanding how roots develop near the trunk will improve our ability to diagnose problems and
develop effective treatments. You will leave understanding how roots develop in the nursery and landscape and what you can do to improve both.

How Trees Grow in Urban Landscapes: Applied Tree Biomechanics, Biology, and Risk Management (Part 1)
Review how tree structure develops, how trees are put together, and how this impacts your daily
pruning practices and bottom line. You will understand how trees respond to forces experienced in the real world.

Break   30 minutes (Refreshments Provided)

How Trees Grow in Urban Landscapes: Applied Tree Biomechanics, Biology, and Risk Management  (Part 2)
Review how tree structure develops, how trees are put together, and how this impacts your daily
pruning practices and bottom line. You will understand how trees respond to forces experienced in the real world.

Pruning Cut Types: Internal Response to the Three Common Pruning Cuts  
There are three pruning cuts used on trees. Learn which is most appropriate for young and mature
trees. Bring home the ability to make the pruning cut at the appropriate spot to minimize pest problems
and decay.

 

Lunch  12:00 PM – 12:45 PM (Provided)

 

Afternoon Session  12:45 PM – 2:30 PM

Developing a Sustainable Canopy Architecture
This is the most important technique to master when pruning young and medium-aged trees. It is the
best way to prevent trunk decay and disease. Learn to choose the right branches and stems to remove
to prevent problems later. With some practice, you can become an expert in this emerging, practical
structural pruning technique.

Effects of Pruning Methods on Tree Survival in Storms
New research provides guidance for better pruning treatments for our trees in storm prone areas. It also
shows us what we should not be doing. This session will provide video and photos of trees blowing in
120 mph wind after receiving different ANSI pruning treatments. This will change the way you view trees
and how to manage them.

 

Outdoor Session  2:30 PM – 4:30 PM
Outdoor Pruning Exercises: Creating and Maintaining Strong Structure With Pruning
Put to use what is learned during the morning presentations. Under the direction the instructor and
students, arborists will make appropriate cuts on the correct tree branches.


Adjourn  4:30 PM
