Annual Arborist Seminar


The Delaware Forest Service urban and community forestry program holds an annual seminar for tree care professionals as well as communities and citizens who want to learn more about how to care for their trees. This year, the program held its 9th Annual Arborist and Tree Care Seminar on October 22 and 23, 2019 at the Delaware State Fairgrounds Exhibit Hall.

The 2019 agenda covered one full day and one half-day. Tree experts presented lectures, outdoor demos, and vendor exhibits on the latest tree diseases and diagnosis, soil analysis, and worker safety.

Attendees were able to earn CEU’s from the International Society of Arboriculture, Maryland Licensed Tree Expert, and Delaware pesticide certification. The cost was $100 for both days (lunch on the first day and snacks included).
