I'm new to caring for perennials during the winter and have a couple questions. I have two coneflowers and a hibiscus. All seem to have gone into their dormancy. Am I supposed to be watering these regularly throughout the winter? If so, how much, approx?
Also, at the end of this last summer 2012, I put in some tiny butterfly bush seedlings that were supposed to be perennials. 3 of the 4 looked like they were dug up and destroyed (probably by the possum I know visits from time to time). The largest of them held out a bit longer, then seemed to 'die' but probably went dormant. Should I be watering that plant, too, although it looks dead?
