spots on Hew Bush

Asked June 6, 2013, 2:06 PM EDT

I have a Hew Bush on my property. I was cutting the bush and I notice these white spots on it and was wondering what they were? If it was something that harms the bush how you would treat it? Thanks in advance.

It's always difficult to provide an accurate diagnosis on the basis of a single picture but based on what I see it appears that your yew may be infested with the wooly adelgid which is common to hemlock trees in this area. The following link provides additional information on the diagnosis and treatment of wooly adelgid. http://ento.psu.edu/extension/factsheets/hemlock-woolly-adelgid

It would be best to take a sample of your shrub with the infestation in a plastic bag to your local Penn State extension office located at:
