Hello, I have 12 boxwoods around the perimeter of my patio. I've had these approximately 5 years with no issue. I do not wrap them up during winter, and never had an problems. There are lot of brown leaves on them now (see pics) and I am concerned they may have Boxwood Blight. Can you tell from the pictures? Also, I can bring in a sample if you would like to see it in person. Another thing I wanted to mention is that I have noticed some red nat size flying bugs around them. I am not sure if this is causing this issue either. Please advise as I do not want to loose these! Thank you for any assistance you can provide.
