Hello there Iris experts. I've had trouble finding my way the Gardening Association. But I think I've got it now. What I need to ask: what about the soil I use? I was planning on mixing a sack of Miracle Grow with some plain old local dirt. We have minimum soil and rock. I will have the soil tested to give me more info. My mother just used Cow manure and she had beautiful irises. I ordered some irises from Schringers. I also have a few bearded Irises left from a prior owner. So please send me all your suggestions. I'd like to start preparing the bed soon. Thank you all, hope your Irises are beautiful this spring. Mary Hughes
