Boxwood shrub problem identification
This does not look like boxwood blight. This looks like damage from an insect pest called the boxwood leafminer.

The least toxic way to manage this pest would be to thin and prune out damaged foliage. Do not shear. Thinning increases air circulation and lets sunlight into the plant. Thus you can avoid chemicals altogether and reduce problems for next year. Monitor the growth and you can send us photos if you notice additional symptoms. See our webpage on managing and preventing
boxwood problems and the video on how to prune. T
thank you! I was debating if it was blight or leafminer. I have been spraying neem oil on it....is that still a good option in addition to the steps you suggested?
No neem oil is recommended.
