Irises: advice, 0 by LouC

One of my iris beds is roughly 8x6 give or take a little. The past 3 years it has been rather quiet with the iris, dutch iris, and the daylillies I inherited from my mother. This year I topped dressed all of the beds with a mixture that must have had magic in it. They are all huge. In addition, our own Mitch Fitzgerald gifted me with many hybrids that bloomed beautifully. So here is my question, the hybrids and larger types have already bloomed. Now the Dutch Iris is trying to bloom and is so much shorter than the others, they are way, way under the foliage. Lost in all of this are the daylillies. So far not one scape.

Would I be doing damage if I selectively cut the top foliage about 10"s to the ground. Some of them must be almost 2 feet. I don't really know what to look for to thin them later in the fall.
The sticky really doesn't address this.

Thank your help.
