I have gotten a few different suggestions on how to move my beloved iris's. For you WI people, we're in the Green Bay area and we're moving to the northwoods, Eagle River area, in two years.
I was told:
1. dig them all up next fall and layer them with mulch in tubs, then bank the tubs with leaves and leave them outside all winter and plant in the spring.
2. dig after blooming and move them to get them settled in so they can winter up there.
I think I'd prefer to dig and replant, but I'll have to plant them in a temporary location until after we build our home and get the landscaping done, then I plan to put them in tiered raised beds, so that would be more digging and moving.
I adore my iris's and I am so worried that I'm going to lose them due to the stress of being moved... what would be the best way?
Thank you!
I attached the max of 5 photos, but I had a dozen different colors blooming this year! Not shown are a tall gorgeous powder blue, a tall white standards with dark purple falls, then shorter (standard or border?) yellow with rusty falls, orangish with rusty falls, lavender with darker purple falls, and solid dark purple.
Then this year I've added Immortality and Batik (to replace the one I lost). A few that didn't produce flowers were a tall amethyst and a tall navy blue, and I'll move both of them since they are in a little more shade than they're happy with. Like I said, I adore bearded iris's! :)
