Christmas tree lovers and tree growers across the U.S. could one day admire new varieties that look great, hold up for weeks in the home, and stand up to a deadly disease that kills popular firs, thanks to globe-trotting research by Washington State University scientist Gary Chastagner.
Known as “Dr. Christmas Tree” to growers for his 40 years of research at WSU, the plant pathologist’s work on holiday trees has encompassed disease management, needle retention, variety improvement, and care of cut trees in the home, along with research into other valuable ornamental crops, including bulbs and cut flowers.
