I don't know much, but I'll try. Hope you're still reading, geebee. Nothing fancy here, I have a few Stella D'ors, in their 7th season this year. Over the past two years I've had more yellowing/browning out at ground level - still good blossoms, but waning. I meant to lift & divide them last fall and again early this spring - but, I failed to do so. They got really sad looking this summer and I did the divisions mid-July and hoped for the best. I divided two in half and another in thirds. The little pieces I put back in my ground are looking very perky and the pieces I gave away are holding their own too. So, maybe you don't have a fungus, but just a need to lift and divide?

Yes, mine are looking awfully shabby. I write it off to our wetter than usual spring and the fact that my dh waters my flowerbeds - VERY OFTEN - and always overhead. (I'm also blaming him for the prostration of most of my black eyed susans and for my grasses looking like they are having bad hair days. LOL) Oh well...he is retired and it is one of the very few things he is happy to do while I'm at work. And it does save me a lot of time and probably keeps many plants alive during our blazing hot weather.

Something new ( to plague our favorite flower!) this year is leaf miners. Although I'd seen leaf miners on columbines,2009 was the first year that leaf miners seem to be on daylilies. Your description sounds like leaf miners. If you have ever seen them on columbine foliage, it looks about the same on daylily foliage. I saw it at some Regional tour gardens this summer and have seen some of it here. Best treatment is a systemic insecticide. I have used the Bayer Systemic rose 2 in 1 where I've seen it here.

Hi everyone, We did get many late freezes last spring so maybe that was why the leaf streak bothered me so much this past summer. I am in the country so we do get alot of wind too. Maybe the cutting off of foliage I had read about was really just some grooming. Unlike just about everyone we had a very dry summer so many leaves just dried up as well, even though I watered a few times. It was just a bad summer all around for my daylilies. They weren't very happy and they looked terrible. Here's to next year. I might look for a fungicide in the spring. I assume you would wait until most of the foliage has emerged. Any new fans wouldn't have the treatment but it might cut down on some of the problem. Thanks for all your help Debbie
