Extension offers tips for protecting boxwoods from disease during holidays

The Henrico County office of Virginia Cooperative Extension is encouraging residents to take steps to protect their boxwood plantings from a potentially damaging pathogen that could be introduced through decorative holiday greenery.

An accidental exposure to the boxwood blight pathogen could destroy a home’s boxwood plantings and crops as well as spread to neighboring properties. Signs of the disease include brown spots on leaves, black streaks on stems and defoliation.

A Williamsburg resident had to destroy dozens of 60-year-old English boxwoods this year after they became infected through decorative greenery that had been left by a trashcan after a holiday party.

To protect boxwoods from potential infection, Extension officials recommend:

  • Using nonboxwood plant materials for fresh-cut greenery decorations;
  • If boxwood greenery is used, make sure it is not infected with the boxwood blight pathogen. The greenery should come from a vendor’s own production facility or from producers who operate in areas free of boxwood blight or who participate in the boxwood blight cleanliness program;
  • Disposing of greenery decorations by double bagging them after the holidays and immediately taking them to a landfill;
  • Using 70 percent Isopropyl alcohol or Lysol spray brand III with 58 percent alcohol to sanitize all materials that come into contact with holiday greenery and other decorations.
