Hello, so I went to my parents house where all my lilies grow and inspected everything. This is LA Courier lily, it looks little mottled, but we had up to -6C at nights like last week, so maybe it's from cold as for example my trumpets all melted at top…
Also younger leaves seems less effected. Any insight will be highly valuable!

-6C??? And here I am melting at +30C

That look suspicious but it can be due to that cold. Keep an eye on it. If the new leaves looks like that than I would kill it especially because it's LA hybrid.

I think it is virused.

what is the white looking stuff on it?

Hello!
Yeah, it was 20C at day and minus at night… Crazy spring!
The white stuff is fungicide I sprayed last week.
Also what do you guys think would it be possible to see virus symptoms oj flowers of such light cream lily as Courier?

Also I talked with my father and he spryayed RoundUp near the Courier. Maybe it could be from RoundUp?
Also I remeber my Kamsberg lilies had this marble pattern last year, when freesing temperatures occured at noght and later they just outgrew from condition. Bloomed fine also.

Leftwood said: I think it is virused.

Thank You! I will wait a week to see if new growth has this pattern. If new leaves are clean could it still mean it is virused?

Round up would have killed the entire plant.
Since other things have "melted", not really, they are turning soft because of the cold, that is what I think happened here.
I am not sure exactly what minus 6 Celsius is, maybe 23, 24 degrees Fahrenheit, that is way too cold for this plant. If you put my butt in a place like that, I am not going to look to good myself!
It's worse then I thought!! 21 degrees Fahrenheit!!! At that temperature plant cells freeze, the cells burst because of the water that they hold. Then they go soft and then black.

Since lilies have a bulb to absorb and disseminate the chemical to a non-lethal dose, it would be very rare if Round up could kill a lily outright in one full dose, let alone an accidental over-spray. The mottling is too evenly distributed to be from an over-spray. And if Dad had given it a good dose all over, this is not a Round up symptom a lily would show.

I can't be certain, but I still think it is virus. Technically, if new leaves are clean, it could still be virused, but not likely. If this is the case, I would keep it, and just keep a watch. LA lilies are kinda known for their virus tolerance, and that's a reason why many don't grow them: they could have a typhoid Mary in their garden and never know it.

Thanks, I will keep an eye on it, hopefully they will outgrow this condition. I think it's from cold because the higher the leaves the less symptoms, some newer leaves has rhis marbling effect just on tips, where the part that was still neatly packed in growing center has none as it was somehow protected from enviroment.

I have heard that LA lilies are tolerant, but I once had one Kamsberg virused in other part of garden and it was really messed up. All blotchy flowers with darker stripes and patches

Also my trumpets just melted from cold, it was -6 or -7C and when sun heat stoke in the following day they just turned to mush. Also mother said there was frost in morning on the top of plants…

I don't know how many times I lived to regret leaving a potentially virused lily "just to wait and see". The last time was a few years ago when a yellow henryi showed very strong symptoms. It's hard to find new bulbs of these so I left it. Ended up removing several Griesbach bulbs from the Big Dig. I was not happy about that, those bulbs were not replaceable.

A regular dose of round up will quickly kill lilies. I used it on a virused Pink Dragonfly (LA I believe) lily back in 2015. I figured the virus would not continue living in the dead tissue. It pretty much melted down by a day or two later. Didn't have to touch it or use my pruners.

I'm really surprised if that is the case, but I'll bet it was because of the already weakened state of the lily. Round up just doesn't normally work that fast. I can't say I have ever applied RU on a lily, but I have with several other kinds of bulbs. It always takes 2+ applications, and sometimes just doesn't work period.

It's on my list now; sometime if I have RU to use up, I am going to try it.

I used round up this spring for the first time on unwanted plants in my reclaimed rock garden. Among my targets were mulberry seedlings, cherry seedlings, dandelions and 90+ % of a tough Spiderwort that spreads by seeds.
The rock garden was a great target because it was a confined space of 8' x 8'.

Results after spraying at nine in the morning. By 6 pm, nothing apparent. By 9 am the next morning, lots of wilting and gray brown streaking. By the next morning after 48 hours, things were obviously dying. After a week, 90% of targets were dead. There was a scattering of newish green shoots. I hit it again and planted in the bed two weeks after spraying.
It really did the job. Wand applicator was very good. I sprayed carefully and thoroughly. Made sure it would be dry for the rest of the day.

Then used it in my elevated beds out front where the Spiderwort spread to and those babies died quickly, within 48 hours.

Rick, I assumed the lily bulbs are quickly dispatched because the scales are modified leaves. I wish it would work as well on my very unwanted Arum Italicum, Ornithogalum and similar spring ephemeral plants. They really suck up my garden space but I keep working at it. One day these will be gone, one way or another.

I will wait for a week until next weekend when I come to parents house again, inspect them again and update you guys on situation

I would agree with the diagnosis of virus. Many lilies are replaceable these days and it is not worth the risk. I just pulled out a twisted leaved trumpet I started from seed a long time ago. Was not that special and out it went.

The higher potency round up works best when needing to use something like that. One and done. Even on a lily.

Hello guys,

Just wanted to update you all who helped on Courier lilies, the lower leaves improved a lot after I fertilized with magnesium and iron.

Upper leaves are completely clean, just maybe a little cholrotic as all my lilies due to poor soil and very heavy rains.

They will be very short like 25-30cm tall this year as all other lilies will be a lot shorter than last year due to cold spring and continues rain every single day.

Update on Courier lilies: they fully grown out of the situation!

Now my Kamsberg seems strange, it has a little twisted leaves with brown markings. I threw the plant out, but it looks like some sort of fungus? Don't mind the darker line on leaf, it is mechanical damage
