I have a problem. In August I thought I was going to be moving in a month or two. I had a nice small bed of about 50 Iris. I dug them up and have been storing them inside since then. Well it turned out I wasn't able to move yet. I'll be moving around April. Should I keep the bulbs inside all winter? Or dig a bed and just cover them up outside until April? Thanks for help, I love these Iris and they're expensive to buy, I don't want them to die
