2018 - Recognizing Insects & Damage in Trees

Recognizing insect damage to trees and plants is achieved by both correct identification of insects and recognizing what insects cause what damage. It is equally important to recognize beneficial insects and understand the possibility that they can or cannot control the problem. This class will aid in your decision making to treat or to monitor.

2018 - Roots

Where do roots really grow? How can we determine if our actions will damage roots? What happens if I do damage roots? What products and methods are available to preserve roots?

2017 – Beneficial Insects, Pollinators, Bees & Pesticides

Predators, Parasites, Prey, and Pollinators. Who is what? Learn how to tell the difference. Once you know the difference you can conserve, augment, and perhaps introduce beneficials. When are pesticides necessary? Proper and timely use can save pollinators.

2016 – Pruning Fruit Trees

Learn there is a difference in training and pruning for fruit production rather than ornamental or shade uses. Different fruit trees require differing pruning techniques but all start with proper training. Sub-tropical fruit trees such as citrus are pruned different than deciduous fruit trees. Deciduous fruit trees differ in pruning needs from each other also.

2015 – Tree Risk Assessment

"Tree Risk Assessment" is a photographic education on what to look for, when to monitor, and how to mitigate. Susan will acquaint you with the tree risk assessment system, looking logically at whether a tree is a risk or when it is of less concern. Know when it is time to prune, cable, bolt, prop, or remove. By taking this class you will learn from the mature tree and a few young ones why it is important to select, plant, train, maintain correctly, and know when to bring out a pro to aid you in your assessment.

2015, 2013, 2012 – Tree Preservation & Conservation

Considerations when undertaking tree preservation and conservation. You will see why good health is not always good structure. Older trees are more intolerant of changes in their environment. Learn if preservation is an option.
