Chinese elm problem

I had a acouple of cutting s I took of a chinese elm that I ha rooted sucessfully. They were all fine and healthy for about two seasons, and now within the last week, they have started curling their leaves long ways(like rolling your tongue), and have turned them upside down, and are crsipy to the touch. The leaves still have their color. I fear these have died, and I'm not sweating it too bad. I just would like to know how to prevent this on my next attempt.

I could use more info. Is there any discoloration on the leaves? Is the rootball dry or wet? How do the roots look? Where were the plants overwintered? Any sign of insects on the foliage? How does the soil smell? There are a lot of causes for wilted leaves and the fact that this has happened after two years to all of them is odd. It could just be that where you live is usually warm enough for the trees to be evergreen but maybe you got just enough of a cold snap to have them drop their leaves. I don't know, I'm asking.

I've had some similar issues with chinese elm having some deformed leaves in early spring about 5 years ago. The leaves that were affected were more succulent and thicker, lighter green and had a similar rolled or warped appearance to what you are describing. They looked like wadded up leaves. Not wilted, just twisted.

I never found any real cause for it. The distorted foliage did not improve, but subsequent growth was normal

I think the most likely possibility is that some infestation of aphid or spittlebug occurred early on and dehydrated the buds as they were forming and the subsequent growth was just wacky.

That's a guess, anyway. I know that aphids can cause distorted leaves.
