Status of Boxwood Blight in Oregon

Part of the 2017 Oregon Master Gardeners Advanced Training series. Boxwood blight continues to be a problem in more landscapes and nurseries in the PNW. Learn about where this fungal disease has moved to, how to recognize it from other disease problems and run a model to determine when it might show up. Master Gardeners are our first responders to help limit the impact of this threat to our boxwood plantings.
