When is the best time to transplant my Iris? I planted a bunch of them in 3 of my raised beds. This will be their 2nd Spring coming up, and I would like to transplant them to other areas. Is this Spring a good time to do that? Here are a couple picture of them. You can see the 3 beds on the right in the first picture. And on the left in the 2nd picture. Should I dig them before they start to grow?
