UI Extension Forestry Tree Clinic

Tree health is influenced by a combination of factors that affect vigor and productivity. Factors may be biotic (insects and diseases) or abiotic (severe weather, misapplication of pesticides) and usually work in combinations that result in the decline or death of a tree or trees.

The UI Extension Forestry Tree Clinic offers free diagnostic and control recommendation for tree and woody shrub problems in urban and forested areas of Idaho.

Findings reported by the UI Extension Forestry Tree Clinic are based on examination of provided information and plant material submitted. Not all tree problems are caused by plant pathogens or insect attacks. Other causes (unusual weather patterns, nutrient deficiencies, pesticides) are often difficult to diagnose without an on-site investigation. Some diagnoses require intensive microscopic or biochemical analysis which we do not have the facilities to accomplish.

The UI Extension Forestry Tree Clinic offers free diagnosis and control recommendations of tree and woody shrub problems in urban and forested environments of Idaho. landowners can work through their UI Extension county offices or sent information and samples directly to the clinic.

Due to budget and time constraints, Tree Clinic personnel are not able to make site visits.

Idaho Master Gardeners originated in 1976, just four years after the program was founded in 1972 by Washington State University.

Now flourishing in 32 of Idaho’s 44 counties, Idaho Master Gardeners provides eager participants with in-depth, research-based education on a wealth of horticultural topics — from microscopic soil organisms to 60-foot shade trees and from thirsty tropical houseplants to drought-tolerant native shrubs.

With their up-to-date understanding of water-smart landscaping, environmentally astute pest control and landfill-saving composting methods, Idaho’s trainee and certified Master Gardeners and Advanced Master Gardeners donate about 16,000 hours of volunteer time annually — a value of about $200,000 in 2008.
