One of the plants I brought up from Florida in May just a couple days ago started declining. It was a solid two big fans - bloomed normally and even had a pod set. Today I went out and one fan was dead( I pulled the dry scape and the dead fan just came with it. Gentle tug) and the second doesn't look so good. I had a struggling bonus plant next to it and it's disappeared though I may still have a crown but that's all. Everything else in that bed is doing fine. Bonus plant was planted just before I went to Florida. I've never had this happen before.
I had someone else mention on Saturday that the same thing had happened to her. Does Amy know the cause and if I can save the other fan left on the bigger plant?

Is it very wet? I had a couple die this year they were planted in a wet spot & I think they rotted. Didn't notice them when we first got back from FL. I tried to save them by moving them to a drier area out of 3 one made it. That one seems to be fine now stunted but growing. Wish I had seen them earlier maybe I could have saved both of the others. They were all new plants from last year.

It does not have to be wet for a plant to get rot, I have one of my driest beds that has lost two plants to rot. It seems if it is very dry then wet, something triggers the rot.

I suggest digging gently in the spot where the dead fan and scape pulled loose to see if there is any sign of a rotted crown. Then gently dig alongside the still-living fan looking to see whether the crown seems solid and healthy, and whether it has healthy roots below it. Do the same where the bonus plant "disappeared". I'm not sure how a plant can disappear unless something ate the tops right down to ground level.

Do you have voles in your garden? In my garden the most likely cause of a loose dead fan + scape would be that a vole ate the crown and/or the roots. But voles don't normally feed on the leaf fans here. So a plant with a top that disappeared but still had a healthy crown and roots was probably eaten by something else.

Ann the dead leaves from the first fan were there- when I tugged to loosen the dead scape they came with it. Almost all my plants are in raised beds so they drain well. I've been watering the newer plants because it has been dry- and yes all of a sudden we've had a few days with storms

When I see a plant acting that way, I will give it a 10% bleach bath. I might dig it up and check on the crown and see how soft it is, but I usually leave it and water it with the 10% bleach solution. I had to do it this past spring with a plant that was in a pot and the leave were turning brown. Once I gave it the bleach bath, two weeks later, I have new leaves coming up. This has happened a couple of times over the 25+ years of growing daylilies.

Ok I dug around a little. There is a thread thin leaf on the struggling one. The fan of the strong one that is surviving still looks strong at the root.
I'm hoping that they recover and don't get worse

Thank you David!! I will do that

Could you give us some photos? These would help us understand the problem better.

Here's what's happening. It's the last fan and it's gone downhill the last two days

Have you tugged on any of the plants to see if they have rot?

I tugged the first scape off this plant and the first fan just came away. The struggling plant beside it has put up a small new leaf. I dug down and it may just be planted too low. But the second fan on the bigger plant is now dying. We've been dry with alternating storms and very hot

By the color it looks like rot is involved. Pull off all dead decaying material, and keep the mulch back. What I do is... one part hydrogen peroxide(on the shelf 3 %) to 3 parts water. Pour it all around the ground and on the fans etc. That kills all bacteria...good and bad. Let it dry out. You want everything bad to die...the good bacteria will come back. If there are any healthy parts below the soil the H202 just converts to extra oxygen. Protect it from getting too wet, rain or watering... put a clear plastic container over it just when moisture is in the air. Otherwise you want plenty of air circulation. Spray it every few days, (do not soak it) with 10 percent hydrogen peroxide mix. Hopefully, it will improve.

But if you have been using bleach you might have a chemical reaction.
So then not sure what you should do. Sorry.

Many blessings for your success!

for the acorn!

May everything work out for the best and have a great week.

Well, I have lost four new plants to what I assume is crown rot. I remember reading this thread when it was first started and making a mental note. When several of the new plants I had received this fall and potted up started yellowing, I treated them with bleach solution and hoped for the best. I think they have all died, though.

My question is whether or not some cultivars are more susceptible or not. Two of the plants I lost are Full Moon Rising DFs. Both came from California with several other plants I had ordered. They were all kind of dried-out looking when they arrived, but the others in the shipment perked up as soon as I potted them and are now doing well. The two Full Moon Rising DFs (along with two other cultivars from a different order) have rotted. This is my first experience with crown rot.

Any chance the shipper might replace these, do you think? The website says their plants are "guaranteed."

I just took pictures of the two plants and sent them to the shipper with a request for replacement. Will let you know what happens.

They are going to send replacement plants.

the photos look to me like the fan is too deep. I have to watch close for this problem, I have lost plants this way. As the first few weeks go by, the plant sinks into the loose soil and the soil ends up over the crown, especially after a good rain as soil washes in over the area where it may been settling from being loose where I worked it as I planted. I usually just lift it up some on one side and shove some soil underneath. This is less of an issue if I plant it in harder dirt and not as much loose compost ect.
