I am not a newcomer to gardening, but am a newcomer at learning how to care for my plants. I have a gardening friend who knows so much that it boggles my mind. She is always talking about aster yellows on her coneflowers and she quit growing them because it always affects them. From her description, I know a bit about what it should look like and I am sure one of my plants had it a couple of years ago. Being of Irish descent and stubborn besides, I decided I wasn't going to pull out that pretty plant and just left it alone.
The next year there was no sign of any problem. In my garden down by the barn, there is a new thing that happened this year. All the cone flower foliage is really healthy and there are tons of flowers, but a few flowers here and there have no petals on the prickly centers.
What do all of you do when you suspect this aster yellows??? My main focus is Daylilies and I am wondering if they can be affected by this problem also.
Thanks for all your expert advice.
