Through over 30 years of adding mulch to my garden the soil is less clay than it originally was. I'm not going to dig up my entire gardens, filled with assorted perennials, in order to further amend the soil. So I just take my lady shovel and dig a very small hole- just large enough to bury the roots, and let the rhizome be close to the soil surface. The iris do great. In early spring and a month after blooming I may sprinkle some low- nitrogen fertilizer around them. Generally they thrive. We don't water except during very prolonged periods of drought. So don't talk me of re-bloomers. After the death of Daughter of Stars, I realized my style of gardening is not likely to accommodate them. Nor do I wish to make a separate bed just for them, and have to water it weekly. That's just not for me.
