Boxwood blight is a disease affecting plants in the family Buxaceae including boxwoods (Buxus), Pachysandra, and Sarcococca plants. First detected in the U.S. in 2011, it has since been found in multiple states and provinces from the East Coast to the West Coast. Boxwood blight has now been confirmed on boxwood nursery stock in New Hampshire. New Hampshire nurseries, landscapers, town officials and residents responsible for boxwood plantings should learn the symptoms associated with boxwood blight. Watch for black lesions on stems, "zonate" brown spots on leaves leading to chlorosis, and leaf drop. If boxwood blight is suspected on recently purchased boxwoods, or plants in proximity to recently purchased boxwoods, please contact the Division and collect a sample for analysis by the UNH Plant Diagnostic Lab.
