Bumps on American Boxwood Stems


jsouth20 added on May 9, 2016 | Answered

I am in Richmond, VA, and I can't seem to figure out what is wrong with my American Boxwood shrubs. Stems are covered with little bumps throughout, though no bumps on the leaves. Stems also blackish towards the base. Some leaves show slight discoloration. The shrub seems to be dying from the inside out (meaning from the center of the shrub outwards). Is this a fungus, blight, or hard/soft scale, or something different entirely? Wish I knew. Hoping someone may be able to help identify what condition this is. Thanks
