Half of my iris's had their foliage die over the winter but the other half did not. They look like they are heading that way, but in reading all the comments, I am still a little confused as to when, if ever, to cut back the foliage. The foliage is about 12 inches long currently, and the top 3 inches is brown, the next 6 has the yellow tint starting to kick in and the bottom 3 is green. Where should I cut these back to at this time, or if not, what phase would I need to wait for next and then where would I cut it?
