Broad Mite on Anemone
While we see broad mite most often in annual flower and vegetable crops grown in greenhouses, realize that this pest has a wide host range and has also been seen affecting herbaceous perennials as well as some woody plants. This year broad mite was seen affecting Japanese anemone (pictured, photo by Dan Gilrein) and climbing hydrangea. Broad mites cause distorted new growth, often with an associated bronzing of the undersides of the infested leaves. Sometimes flowers can be affected, with petals showing discoloration.
