|I have 3 planted at house foundation about 10 years ago. Over past two years, one has been gradually failing to leaf more and more each year and the branches are dead on about half the shurb, the leaves on surviving half are smaller and lighter yellow than the the two healthy ones. This year only about 1/3 of it had leaves. The one next to the dying one is now starting to have same symptoms,lighter and smaller leaves. The 3rd one is still healthy & lime green. What can I do to prevent further damage?

|Based on your description I am not certain what is happening to your barberries. It is possible that there is a root problem where they have encircling roots below ground that now are beginning to basically strangle the plant causing stunting and dieback. It is also possible there is a disease problem such as verticillium wilt -- the symptoms sound as though it may be this. I would suggest you work with your local county extension to obtain a specific diagnosis and then wotk from there. I'm sorry about your barberries.
