Determining Blueberry Cold Hardiness in Washington

By Gwen Hoheisel, Lisa Wasko DeVetter, Clark Kogan, and Lav Khot

  • This project developed predictive cold hardiness models for ‘Duke’ and ‘Liberty’ northern highbush blueberry in Washington State. The cold hardiness models are available to growers at WSU AWN.
  • A scientific paper on the model can be viewed below:
