It has been stated by specialists at the University of Kentucky that 85% of the diagnostic tree samples that are submitted to the lab and/or questioned by extension agents and homeowners are a result of a below ground issue.  Since a large number of issues occur underground and are not visible by the eye, it stands to reason, that it is best to prevent tree issues as opposed to treating or fixing tree issues.  With that idea in place, in September of 2023, the Harrison County Horticulture Agent offered a class called Trees for the Landscape: What to Plant and How to Plant.  

Trees for the Landscape: What to Plant and How to Plant, hosted by the Harrison County Extension Office, proved to be a transformative experience for the attendees, encompassing the topics of site assessment, species selection, installation, and maintenance.  With sessions tailored to accommodate schedules, the course was offered twice, during the morning and again in the evening. The group of 9 participants was a smaller group than hoped for, but it provided an opportunity to dive deeper into the topic and elaborate on specific needs and questions. 

From the information shared, attendees gained insists into factors influencing tree health and longevity, empowering them to make informed decisions in their landscape projects. Species selection discussion provided an understanding of matching trees to specific environmental conditions. Correct installation techniques were shared, and comprehensive maintenance strategies discussed will help ensure the preservation of the tree’s beauty and vitality. 

In addition to the PowerPoint presentation and class, participants were given a folder including a large variety of publications to use as a future resource.  Those resources included: Native Trees to consider (a list of native trees including species, variety, size, and favored growing conditions), ID-89 How Dry Seasons Affect Woody Plants, PPFS-OR-W-17 Leaf Scorch and Winter Drying of Woody Plants, HO-93 Trees and Compacted Soils, HO-94 Trees with Minimal Insect and Disease Problems for Kentucky Landscapes, ID-237 Soil Percolation: A Key to Survival of Landscape Plants, and PPFS-OR-W-30 Common Problems of Common Trees – An Index.

The feedback from participants speaks volumes about the course’s impact. A survey indicated a unanimous increase in understanding from before the class to after the class, in all four topic areas – site assessment, species selection, installation, and maintenance. The survey also indicated that all participants either Agree or Strongly Agree that the subject matter was timely, the information was practical, the program was educational, and they would recommend the program to others.
