Question From: Monroe, Michigan, United States
Q: I have a pyramidal golden barberry that starts out very healthy with lots of new growth each Spring. As the season progresses, it becomes sickly with leaves on some of the branches turning brown and dying off. This year I have also noticed spider type webbing in these affected branches. With what do you suggest that I treat the shrub? Thank you for any advice you can offer.
Your barb is suffering from spider mites. A stiff spray of water will knock them off. Try to get the undersides of the leaves. Repeat this process every day for a couple of weeks. You can also spray with a miticide. I prefer AzaMax as it is OMRI listed and safe for you and the environment. Best And Happy Yardening, Nancy
