Willamette Nurseries in Canby, Ore. was hit by a fire over the weekend that caused at least $500,000 in damage. The Canby (Ore.) Herald and The Oregonian (Portland, Ore.) have the details. The nursery provides rootstock as well as bare-root shade and fruit tree liners, shipping them to all parts of the United States. Firefighters from multiple agencies responded. They managed to save the nursery’s cold storage facility and contents, valued at more than $1 million. Fire officials are pointing to the possibility that rags soaked in wood-staining oil spontaneously combusted and started the blaze. However, no definitive determination has been made.
