Could you post a pic of the daylily rust? I seem to have a lot of leaf streak this spring; at least, I hope it's just leaf streak.

Sorry to hear your having a tough time this season. I've not heard of the clematis virus so I need to go look that one up.

I just keep hoping we get through the month of April without too much plant damage. Yesterday it was 85 degrees here but today we dropped right back down and frost is predicted for tonight again. I have so many plants to move but who can wash daylilies when your hands freeze within minutes?LOL

Oh man Celeste, I am so sorry! I don't really dislike Knock outs...they can be quite pretty, and I have a few myself. They just aren't my favorite.

I do understand the issues. I am watching like a hawk since so many think=gs go wrong now. Make sure you really have rust and not something else. I sprayed for thrips, and it is raining, so I will need to spray again. On the bright side, I got my first (rain soaked ) blooms today. Will post later. Hope everything straightens up for you.

Wow, I didn't think daylily rust existed in zone 7 or colder. They just changed my zone to 7, I've never had it here, thank goodness. This winter being so very mild though, I can see it happening if you bought some with rust. I haven't heard about the clematis disease either. I've been hearing a lot about hosta & HVX. I got most of my hosta from box stores & trades, so if anyone has it, I'm sure I do, but haven't been able to ID if it is there. They all seem to be growing nicely, & looked great before they got frost bit :( The leaves are getting browner every day. I saw some aphids on a couple of my daylilies before the freeze hit, but they seem to be gone-knock on wood. Hopefully the cold took them out, the freeze should have done something good.
So sorry you are having these problems, it is so hard for a gardener to lose plants like this, & so many at a time.

ngraham, we get rust in zone 7. It's cold enough though in winter ( not this one) that it kills it off!!

So sorry Christine. Hopefully, things will improve..Ellie

I've gotten some kind of iris problem that I have never had before. The leaves are turning spotted-looked it up and it looks like pictures of iris leaf spot fungus. They were just starting to recover from iris borers a couple years back. :(

Christine, are you sure you have rust? It's usually so cold here I don't have to worry about it. I have several though that have spring sickness.

Lisa, cut off every infected leaf, spray the plants with fungicide and you may be able to irradicate it.

Between this and Maryl's post, I have a feeling that this is a year that a lot of people who are normally too far north for much rust are going to be dealing with it.

I had a fair amount of rust in January and February, treated and gone by March. I'll post a couple pictures for everyone's benefit.

Here are some pictures of my rust in late January. NEW PARADIGM was definitely the worst, but everything in my front bed was eventually affected. And with several weeks of cutting and Cabrio, it vanished and these plants all look good again.

Thanks for posting the pics Nate. I guess I should be watching for rust, although I suspect that even though they have changed my zone, I "shouldn't" get it here. This was a very unusual winter here though.

This has been a learning experience. In the future I am going to be much more careful with new daylilies and hosta. I will do the bleach soak for the daylilies. As for the hosta, the recommendation from folks at the hosta forum is to isolate a new hosta, perhaps in a pot, for a couple of years before planting in the garden. Once a hosta is infected with HVX, there is no cure, it might spread to your other hostas and you can't plant another hosta in the same spot for at least 2 years.

Here are some daylily leaves. Is this rust?

Thank you all for your concern and help.

Christine: Just from the pic, I don't think so. One way to tell for sure is take a white paper towel or tissue and run it along the leaf. If you see an orange colored stain on the paper towel/tissue, then it is rust.But the pustules are the sign of rust. Be sure to wash your hands/tools etc thoroughly after touching the leaves so you don't spread it to other plants if it is rust.

It looks like leaf streak to me.

This is building up to be a rough year here as well. We had eight days of record high temperatures in March, then it froze in April. I have leaf streak all over and it looks terrible, but weather it will effect blooms or not I can't tell. I probably have Spring Sickness as well but it's hard to tell with them all curling up from streak. The lawn has fungus in it and all the grass looks speckled, and I got two deer ticks on me yesterday. My wife gets sinus infections when the pollen count goes up and she is already on antibiotics. And the weeds are knee high already. And now we are having a dry spell after very little snow last winter. But I am embarrassed to complain when I see the destructive weather in other parts of the country.Still, I don't know how the apple farmers are going to make out around here. The April freeze did some damage.-------------------------------------------Weedy

Christine - I agree that what you have is leaf streak.

Shive, Mantis, and Julia - thank you. This is a relief

Weedy - I can write my name in the pollen on my outdoor table. Atchoo. I hope your daylily bloom will not be affected.

The middle leaf looks like classic leaf streak. Leaf streak usually begins in the middle of the leaf and then moves outward. Sometimes leaves can get a similiar look when they suffer from either drought stress or heat scorch. The foliage here had looked really good until about a week ago ( it has been very dry) and then in many parts of the garden has begun yellowing. Since I have been spraying, I don't think it is leaf streak but rather, drought stress. Ugh. We finally got .8 rain yesterday so I hope the drought stress causes no further damage. I'm worried enough about bloom season being about a month early with the garden on Regional tour!

So sorry for all the gardening troubles that are going on. Hopefully you can turn the corner and get positive reasults sometime soon.
