Bearded iris- really a maintenance nightmare?
In most of my perennial garden books, bearded iris are described as maintenance nightmares, requiring careful management so they do not succumb to borers or rot. I have indeed lost several to rot over the past year as the rhizome got buried too deep. Yet, I see bearded iris in people's gardens that are covered with soil and appear to be completely ignored, and yet, they come up year after year. Do they know to do something I don't? They are so beautiful I can't imagine a garden without them, but perhaps other forms of iris are just much easier. Any thoughts??
