I have 3 kinds of barberry shrubs. The rose glow and the crimson pyburn thrive, but every golden barberry I plant lives for a season or two, but then they die. Everything I read indicates the care, soil, etc is the same for both types (red and golden), so I don't know what I am doing wrong. any advice. I am in zone 7.
Note: the leaves appear to start shrinking and they start turning brown and look as though they are starving for water, but they get the same amount of water as the other shurbs. Once it looks like this, it is dead within a couple of weeks.
