You see, how I can be thankful for my 6" of snow now. Instead, I could have had an impromptu destruction visit from a tree service, felling trees all over the gardens, lets not forget all the tromping. That kind of stuff gets done willy nilly when there's no plant supervisor out and about. Yup, that would make me fume too. I hope they used those trees to build a dog house!

No, doghouse. I did find me a good switch. I'm happy to report, there was very little damage done. The guy did a great job, he only crushed a clump of ditch lilies. He had no choice, it was the ditch lilies or our phone line. I have plenty of ditch lilies out by the ditch. The guy even swept the saw dust off of my Iris's. I wasted no time, thanking him and I slipped him a tip for the great job. He truly saved my husbands life.

The only casualty was a Ditch Lily...you're golden!

I doubt it killed them, ditch lilies are tough as nails. I'm going to dig them up and move them to the ditch. They will look funny growing out in the middle of the yard now that the tree is gone.

I'm paying more attention to the different types of foliage this year. Truthfully, foliage is all I have other than Spring bulbs at this time. Thanks to this thread, I'm going to start taking pictures of my foliage, as well as my blooms, for my spreadsheet. Becky This has been a great thread.

Agreed Karen, thanks Becky!

I found the opinions of all to be very informative! Thanks to all who posted a reply!

Since we are on a discussion about foliage, I am hoping @sooby reads this post. I am seeing yellow leaves on most of my registered cultivars including my rust resistant daylily cultivars. I've checked the leaves and it is NOT rust on most of them. I can't find the link you shared with everyone that showed what a leaf looks like from thrip or aphid damage or spring sickness or any other ailment. Or .... do some of the leaves turn yellow like that in the Spring when new growth starts again? It is the outer leaves, not the newer leaves. I've never really paid any attention to the yellow leaves before, but now I have rust resistant cultivars and want to make sure it is not a pest or another disease taking a toll on my plants. If it is normal leaf life cycle, then I am relieved. If not, I need to take care of the problem ASAP. Thanks in advance for you help. I find your photos are very helpful when it comes to trying to determine an issue with the foliage.

I noticed today that 'Heaven's Portals' seemed to be very heavily afflicted with yellowing leaves. I think it is leaf streak. But I also have a lot of plants showing yellowing leaves that I think might just be old leaves dying off. It seemed to me that the majority of my plants showing the most yellowing leaves happened to be the ones with scapes. I am thinking that maybe that is putting extra stress on them. I also was thinking that the cool weather we are having is a possible cause.
Edited to add:
Also showing more actual rust on plants in the garden as the cool weather continues, I pulled a large basket of leaves today.

I recently got rust on a daylily which hadn't had it before, and a couple of my older seedlings are looking a little suspicious (not counting the one I think *will* turn out rusty, but which I'm waiting for confirmation on before I pitch it). Not obvious rust, not leaf streak, but sort of lighter colored areas on parts of the leaves. I don't know if that means incipient rust, or if something else is going on. Those seedlings certainly are fed well enough, so I doubt it is nutritional.

Some years ago (sorry, I can't point to the issue) the Daylily Journal had a really good article with some great images showing the effects on daylily foliage of different diseases and also nutritional problems. I really wish the AHS would take that article and permanently pin it up on the AHS website somewhere, for easy reference.

Polymerous - It could be thrips or aphids. Believe me, they can do some damage to leaves, too! I need to know what is the culprit so I can treat my plants (accordingly). Don't toss any plants yet, make sure you know what is damaging them first. It isn't always rust damage .... believe me.

beckygardener said:Different cultivars produce different foliage types, correct?

What I have discovered.... and maybe this is not accurate, is that thin foliage is less prone to rust than wide foliage. I assume because rust needs an area in which to spread. Skinny leaves don't provide much area. But is that assumption wrong?

One thing I found this spring after a hail storm (small hail but enough to coat the ground) was that those cultivars with wider leaves had more damage (split/broken leaves) than those with narrower leaves (which had little to no damage). I guess that's to be expected due to more surface area. At least it occurred before any scapes had begun to grow.

If it's an all over yellow and only the outer pair of oldest leaves per fan, it's probably either natural leaf aging or it could be nitrogen deficiency. I don't think it would be aphids because they congregate in the centre. Thrips wouldn't be only the outer leaves either. On foliage thrips cause a silvery spotting and streaking effect. I wouldn't be too worried about yellowing that is confined the the very outermost leaves. If nitrogen deficiency got worse it would start to turn more leaves pale all over (yellowing only between the veins would be something else and it doesn't sound like that's what you're seeing).

Here's a pdf link I found about nitrogen deficency with pics.

Thank you to both sue and Vickie. Very helpful. Sounds like mine are aging leaves.

@sooby - could you please add your website link again. You had some great photos on there as well.

This one Becky?

Thanks Sue, Vickie and Becky for the great information and links, it's very helpful!

THANK YOU, VICKIE!

That was just the article I was thinking of!

Glad to be of help!

Sue - Yes! Those are the photos I was thinking of. Gardeners needs to pay close attention to what the damage actually looks like to verify whether it is rust or some other pest/disease. They can look similar until closer examination.

Thank you, Sue!

Yes, yes, great info in this thread. This is one to read more
than once, and take notes.

ADMIRALS BRAID is one of my erect foliage ones. It and ASH ROSIE. However, the leaves do eventually turn over near the tips.
