Course Title: The Arborist Short Course: Advanced Tree Knowledge for Better Tree Care

Delivery Method: Live Online

Course Description: This course examines the science and techniques for tree health and longevity by understanding soil conditions and improvements, establishing and maintaining root health, strategies for training young trees, maintaining branch structure, pruning strategies and techniques, and tree planning and selection for site conditions.

Learning Objectives:

Learning Objective 1:
Learners will be able to explain how soil compaction affects tree health, and they will be able to identify ways to avoid damaging soil.

Learning Objective 2:
Learners will be able to describe methods to keep water where it needs to be to benefit trees, and they will be able to create the optimum environment for tree roots.

Learning Objective 3:
Learners will be able to discuss biological health techniques to increase tree vigor, longevity, and stability.

Learning Objective 4:
Learners will be able to describe methods for training young trees, maintaining branch structure, altering tree growth patterns, and how and when trees should be pruned – all of which increase tree health and sustainability.

Learning Objective 5:
Learners will be able to explain predictable tree failures and how the can be avoided by selecting proper materials, adhering to proper planning techniques, and following proven planting methods.
