Blue Spruce Christmas Tree Pests
I am looking for information regarding pests that affect Blue Spruce Christmas trees. What is the number 1 pest affecting the Blue Spruce Christmas tree? Who might I contact regarding Blue Spruce Christmas Tree pests? This information is for a term project at Clackamas Community College.
I would say the most common would be white pine weevil followed by cooley spruce gall adelgid. Spruce is not a common Christmas tree, more common as a landscape tree. You might try the OSU Master Gardeners or your campus library.
