I know this is a really basic question, and I did try to search for it using the "search"
I have a lot of old fashioned noid yellow iris, They were here when I bought my house, planted in an area to shady for them to bloom. I have moved and divided them several times over the past 10 years, and they are beautiful until mid-late July.
The foliage then starts yellowing and dying back, and generally looks terrible. It takes a lot of time to cut leaves back individually as they get ugly. At this point in the season can I just cut them all back to 3-4" tall? Have they had enough time to store up nutrients for the winter?
Thanks for the help
