Guest garden question

My co-worker Sandy has a problem in her garden ...
Take a peek at this plant. She said the tag called it a "Tall Fall Daisy" and it's getting these weird brown stems - apparently they die off one at a time. As you can see from the photo - one is in full "die-mode" and there's one that's met its demise right next to it.
I have no idea what would cause it to do that. The other stems are seemingly happy but apparently they eventually falter too.

Any ideas what might be causing this?

The same thing happened to my phlox that I planted. It seemed to be dying from the roots up.

Well Beth I wish I could give you a great answer but I can't. Hopefully some other blogger will have an answer.

Glad to see you online. Hope you are doing well.

I don't have this exact Daisy, but I do have Daisies (they're more Coreopsis-like, not sure of the variety) and they do the same thing as the plant goes through its summer cycle. Since mine are more like a bush with narrower stems, the dead ones are much less noticeable. I just cut them off at the base and the rest of the plant is perfectly fine. I've had them for 6 years and every summer they do the same thing, but they always come back with a vengeance! Hopefully Sandy's will do the same.

Hi Beth, it looks like a fungal disease, mildew or something similar (I'm not a expert so this is just my guess). If her plant is one of the aster family, many of them are prone to mildew. Cut the infected stems down to the ground and dispose of them away from the garden. If the plant continues to have problems she might decide to replace it with something that is more disease tolerant.
