Browning foliage is one of the reasons I would like to cut back on the number of daylilies I have and add other perennials that do not have this tendency. The garden just looks so tired and bedraggled now. I've cut the foliage back on 20 or 30 daylilies to clean up the garden some, but carpal tunnel syndrome limits the amount I can do each time. A few of the daylilies I cut back a couple weeks ago are already getting pretty, green leaves again.
