Delaware tree seminar on Oct. 22 & 23 in Harrington
The Delaware Forest Service’s urban and community forestry program will hold its 9th Annual Delaware Arborist and Tree Care Seminar on October 22 and 23, 2019 at the Delaware State Fairgrounds Exhibit Hall (18500 S. DuPont Highway, Harrington, DE 19952). While targeted primarily to the tree care industry, the event is also open to the public—particularly HOA’s or communities who want to create better communities through healthy trees.

The 2019 Delaware Arborist Seminar Agenda covers one full-day session on Oct. 22 and one half-day session on Oct. 23. Attendees can learn the latest developments in tree care through lectures by academic and industry experts, outdoor demos, and vendor exhibits featuring the newest equipment and technology.
Tree professionals can also earn continuing education credits toward accreditation from the International Society of Arboriculture (ISA), Maryland Licensed Tree Expert, and Delaware pesticide certification.
