Do Daylilies die back in August after blooming? I have quite a few on my property and they all seem to do this. They were planted before we lived here and don't know much about gardening or daylilies. Thanks!
Indeed, there are some that go " summer dormant" after blooming. the foliage dies back. In my climate, (zone6/7) the foliage does grow back in the late summer- early fall.
In my zone (which until recently was 5b but recently was reclassified as 6a), the leaves turn yellow in late August/early September. I cut them off for tidiness, and the plant goes dormant until next year.
