My rose glow barberrys look awful right now (I have 3 of them in a grouping). I have had this problem every year since I bought them. It looks like a worm has chewed on at least every leaf and some of my branches have no leaves on them at all. Does anyone else have this problem? I read in my shrub book for MN/WI that barberrys don't usually have problems unless stressed. How can they be stressed every year? So, I am thinking of replacing them with new barberrys but wonder if I would have the same problem; or would I be better off putting something else in the spot; or if I put them in a totally different spot would I have the same problem? I really want to keep that color as it looks terrific against my house. Any suggestions are greatly appreciated! Thanks, Jodi
