LP073: NEW-Woody Plants: Their Appeal and Uses in the Landscape
A woody plant is a plant that produces wood as its structural tissue and thus has a hard stem.

• The advantages and concerns surrounding woody plant choices will be covered, along
• includes discussion of plants suitable for rain gardens, attracting birds, invasive species, native species, hardiness zones, and suitability to soil type
• Over 120 species will be covered
• Plant care, including pruning will be touched on.

LA005: Below the Ground: Introduction to Soils and Tree Roots
Approximately 40 percent of a tree's biomass is below ground, as a vast network of roots. Because roots lie out of sight, their care and protection are often overlooked, resulting in poor performance. Understanding how roots grow and the importance of healthy soil is vital knowledge for anyone working with trees to understand.
This seminar will cover:
*Basics of tree biology
*Root growth and soil science
*Importance of healthy soil and proper nutrient cycling
*How to assess soil conditions to improve soil health
*How to help protect tree roots during construction
*Routine maintenance for root and soil health
Participants are encouraged to ask questions and share case studies from their own work experiences. Landscape designers, technicians, contractors and architects, along with property managers, groundskeepers and arborists should attend.
Note: ISA continuing education units (CEU's) available.

LA001: NEW-Trees and Shrubs: Planting and Maintenance Practices
Don't waste time and money planting incorrectly.
This seminar explores how to maintain trees and shrubs so that they perform well in difficult urban settings. An introduction to tree and shrub biology is followed by a discussion of main stresses, including drought, construction damage, and lack of nutrients. Participants will learn how to assess a planting site and the proper techniques for plant selection and placement.
This seminar also covers the basics of proactive tree and shrub care, including planting,mulching, watering, soil enrichment, staking. Participants are encouraged to ask questions and share case studies from their own work experiences.

LA012: Fungamentals 1: The Basics of Tree and Fungi Interactions
In the urban environment trees and fungi are inseparable. The role fungi play in keeping trees alive, and on the other hand shortening their life, is not only critical to arborists and clients, but also those of us who maintain and build landscapes around these trees.
As professionals, we can bring this world to life for our clients, protect their assets from needless damage during construction, and bring immense value through deeper understanding.
This seminar will cover ID skills for decay fungi, introduce ecology of mycorrhizal fungi, fungal pathogens and how cankers form, techniques for preventing the effects of harmful fungi during and after construction, as well as management techniques for both young and old trees that play host to cankers and other common fungi.
Participants will leave with confidence in field ID, explaining fungal pathology to clients, and understanding the cost management and prevention of issues.

LA013: Fungamentals Theory 2 and 3 – Theory of Planting, Pruning, and Root Management
Join Kyle for a review of industry best practice for planting, pruning and root management. Focus will be on understanding the relationship between trees and fungi, and the role fungi play in these three aspects of plant health care.
Although not required it is recommended that attendees have an in depth understanding of Fungi and Integrated Pest Management principles introduced in Fungamentals 1
Details Covered Include
Half day spent reviewing the intricacies of the relationship between trees and fungi throughout their life cycles.
The second half will introduce the relationships between trees and fungi that live on roots (decay and mycorrhizae), tools for minimizing impact while working around roots and ID skills work.
Participants will also get the chance to inspect and dissecting planting stock that is applicable to technical arborists and plant healthcare professionals.
Expectations and Goals
To improve skills for fungal field ID, the role fungi play in choosing trees for planting, and once planted, how fungi interact with trees above and below ground. The focus is to improve comprehension of the interactions between trees and fungi, built on a scientific foundation. Understanding and communicating signs and symptoms of root impact in the canopy.
Other skills explored - diagnosis of decay, symptoms of root impact in canopy, understanding the relationship between proper planting, root death, and when to use pruning techniques (above and below ground) to preserve trees and extend their valuable service life.
Bracket fungi ID skills – Review of Ganoderma, Kretzschmaria, Armillaria, Laetiporus, and Pholiota
