For the past few weeks I have been removing the old flowers from the daylilies in my garden, a daily chore for the open daylily flower lasts but for one day. I have been removing yellow foliage from the plants at the same time.
With an exceptional amount of flower production this season and the extremely dry weather the plants have been under stress and an abnormally high amount of yellow foliage appeared. Most of my daylilies are not rebloomers and many have finished flowering for the year leaving behind a tired clump of foliage that is slowly collapsing and yellowing out.
It is best to cut these clumps to the ground now. Daylily foliage will regrow and produce a beautiful mound of green foliage that will last until frost and this healthy new foliage will energize the roots for next seasons bloom.
