Gabe - since you have increased the number of iris you have greatly in just the last two months it is surprising you want to increase them even more. You surely have more pots than me! But at this time of year I would let them spend some time just growing or you won't have any developed enough to bloom in the spring. To that same point, it is a blessing if you don't have any trying for re-bloom right now as the blooms are likely to freeze. Better that the rhizomes just continue to gather energy for spring bloom time. It is sad to see an iris put up a bud that freezes now then gives you no spring bloom.
