Hi everyone!
At the end of the past summer I moved Little Show Stopper and Siloam Merle Kent to a new spot in the garden. Not really so far from where they were before. Little show stopper was divided too.
Now they aren't growing, leaves are like a young seedling leaves. SMK lost two fans they looked like rotted at the crown. I lifted them and found that roots are like rotting, many are empty and very soft inside.
The soil is the same heavy clay soil they were before. SMK never grew much but LSS was a very big and flowery bush.
I don't know what's happening so I thought of asking.
Any suggestions?
Many thanks!

Have you had a lot of rain? Daylilies love rain, but not constantly wet feet.
Do you see any new roots forming? As new roots form, some of the old
roots will die off and appear brown and empty as you described.

You might try adding some amendments to the soil even maybe some
loose potting soil to loosen the clay if the clay is rather solid. It does take
time after division for the plants to adapt to the trauma of division,
although that should have happened sometime before winter.

Did you have any severe freezes during the winter? When you lifted
them, did you notice any softness of the crown, or is there a nasty odor
present?

Thanks Shirlee, we had rains but the past year it has been worst and never seen any root damage. The clump was so big that I could never imagine a shock like this. We had some light freezing nothing too bad but it was the first year after many that we got below 0°C.
I saw many small white insects or larvae I'm thinking they were feeding on rot... I put both the plants in pots with a good potting mix. One fan is detaching from the crown. I'm attaching some pictures to show the roots. The "biggest" fan still has some good roots, some new tiny roots growing.






Thank you!
