Hemlock Treatment Demonstration at Warren Wilson College

Hosted by: Hemlock Restoration Initiative
Jun 13, 2026
9:00 AM - 12:00 PM
  • The Hemlock Restoration Initiative (HRI) is hosting a demonstration of chemical treatment methods to control the invasive hemlock woolly adelgid (HWA) on Saturday, June 13th from 9am to 12pm at Warren Wilson College in Swannanoa, NCHemlock trees in western North Carolina are an important and irreplaceable component of our forests. These trees have been suffering for over two decades from hemlock woolly adelgid (HWA), an invasive insect that can kill the tree in as little as four years.

    However, hemlock management is simpler and less expensive than ever before. This hands-off demonstration will be useful for landowners, natural resource managers and tree care professionals. We will use the trees on-site to practice assessing hemlock health to determine the best treatment options, and HRI staff will demonstrate the HWA chemical treatment methods used on national forest and state lands. These methods are available to all private landowners in North Carolina without obtaining a license or certification. We will also discuss applicator and environmental safety, special considerations and guidance for hiring a tree care professional. The backup weather date for this event will be Saturday, June 27th. Please also note that the demonstration will occur on a slightly sloped surface and some demonstrations may require climbing a short hill to view them.

    NC pesticide applicators can earn 3 credits for attending (categories G, L, N, D, and X), and ISA members can earn CEUs (credits currently pending).
