This aster, that was so beautiful in this photo taken last year, is plagued with powdery mildew now. What I want to know is, should I just cut it back nearly to the ground, to get rid of the mildew, and let it grow back? I realized it might not bloom anymore, but that's okay. I just want a healthy plant.
I have cut back monarda with bad mildew and it did grow back. I have never had mildew on any asters yet. Mildew gets to be so bad though that the leaves certainly are not functioning so you might as well IMO.

That's what I was thinking. I had powdery mildew on Coreopsis 'Zamfir' last year, and I cut it back right before frost and it came back this year quite healthy. I'll be cutting the aster tomorrow. Thanks!
Kylee,
That's a shame,,,such a beautiful flower. But, like you said,,,healthy plant is always the first thought.

Well, that's what it looked like LAST year. This year, not so good. :-(
Aw, it'll be lovely again next year. I know how it feels to have to cut one of your babies down.
Yeah. It's in a prominent location, too!
oooo, that stinks. Um, my Mom uses a silk plant,,,maybe that would work for this year?,LOL
LOLOL. Kelly, you're a brat. I still love you, though!
LOL,,,you too,,,She does though,,,I'm completely serious ask Equil,,,,she saw it.
I remember reading about that!
And more bad news........my magnolia tree/bush has powdery mildew, too, and I am NOT cutting THAT down. :-(
Is there any way to treat powdery mildew?I have it really bad on my dahlias and now my honeysuckle vine.I sure don't want to cut them back now.Any ideas?
Yeah, I've got some Ortho stuff that I use for the roses when that happens. But strangely enough, the roses have been fine. (Knock on wood.)
Cedar - it is tuff to clear up once it is on there. A systemic fungicide applied to succeptable plants near problem times help. Honenysuckle is one of the worst and I don't think there is anyway to keep it totally off. I have only had mildew on a dahlia growing on the ground. The organic people could tell you how to use milk also.
My honeysuckle looks pretty pathetic right now so maybe I should go ahead and cut that back.As for the dahlia I think I might try a fungicide and see if it will snap out of it.I will also check into some organic gardening help.
Thanks for the help!
I don't know if they have anything, but you might check GardensAlive! (http://www.gardensalive.com) to see if they have something organic. They've got lots of stuff that is.
Thanks for the link kbaumie.

Gosh, I think I'm going to unwatch this thread,,,,,this seems to be catching,,,LOL
Well, we've had such hot, dry weather, I'm not surprised!
Sorry about that, Kelly! :-( What has it at your house?
Nothing yet,,,but don't want to get it,,,,LOL
Here is a thread sitting right "next door" to this one, on treating powdery mildew in phlox. A peroxide solution appers to be another harmless spray:
