Learn How to Diagnose Tree Problems at Workshop

MANSFIELD, Ohio — Call it learning triage for trees.

The Ohio Woodland Stewards Program is holding a workshop on diagnosing tree problems — from holes in leaves to galls on twigs, thinning crowns to dying branches — on Aug. 5 in Mansfield.

Kathy Smith, coordinator of the program, said participants will learn how to tell if a tree needs immediate attention or not. Benefits can include faster treatment and better recovery on one hand and less urgency and expense on the other.

The workshop is mainly for tree and landscape professionals, she said. It offers continuing education credits under the Society of American Foresters’ Continuing Forestry Education program and the International Society of Arboriculture’s Certified Arborist program.

The Ohio Woodland Stewards Program is part of The Ohio State University and its College of Food, Agricultural, and Environmental Sciences.

The workshop’s instructors will be forestry and plant-disease experts from Ohio State University Extension, which is the outreach arm of the college.

How to do the detective work

As part of the agenda, a crime-show-sounding session called “The Lineup” will look at “The Victim,” “The Suspect” and “The Sentence.”

Another session will give hands-on diagnostic practice with bark, leaf and twig samples.

What’s been bugging Ohio

Other sessions will cover common and not-so-common tree problems seen in Ohio during the past year — including mites, aphids, bagworms and tent caterpillars — and resources to turn to for help.

The workshop goes from 9 a.m. to 3 p.m. at Ohio State’s Mansfield campus, 1760 University Drive. The campus is about 70 miles north of Columbus and 80 miles south of Cleveland.
