Hemlock treatment is easier and cheaper than ever before! To educate landowners and land managers about the various options available to protect their hemlocks, the Hemlock Restoration Initiative will be giving a hemlock woolly adelgid (HWA) management workshop in partnership with the Highlands-Cashiers Land Trust and The Mountain Retreat and Learning Center on Friday, March 15, 2024.

Please read the information below and follow the registration link to sign up.

Workshop Description

The workshop will be from 9 a.m. to 4 p.m. on the grounds of The Mountain RLC outside Highlands, NC. We will use the trees present at the workshop site to learn and practice a variety of methods to treat hemlocks available to all landowners in North Carolina. Participants will receive in-person instruction and hands-on practice. We will cover the details of chemical treatment, including:

  • How to identify hemlock trees
  • How to assess hemlock health to determine appropriate treatment
  • How to select, mix, and safely apply products
  • Ways to reduce off-target risks to the environment
  • When to seek help from a tree care professional

A series of short videos will be provided to watch before the field session. The videos cover background information relevant to the hands-on training. Topics covered include the ecological importance and value of hemlocks in urban and community forests, the biology of HWA and other hemlock pests, integrated pest management strategies, and the role of the Hemlock Restoration Initiative in North Carolina’s various hemlock management efforts. A link to the videos will be shared by email upon registration. If you have concerns about being able to watch the videos before the presentation, please reach out to us.
