Hibiscus cuttings: leaves already wilted

Hello,
I'm an inexperienced gardener. I'm trying to learn about propagation and am running a few experiments with some different plants. I have taken seven tip cuttings from a hibiscus, pencil-thick, slightly woody. I've cut the leaves back until there are only 2-3 remaining. I've planted in a soil/river sand/peat mixture and put them under plastic. I've sprayed them pretty much daily. But now, less than 2 weeks have passed and all the leaves have completely wilted and shrivelled. My question is, can I expect the leaves to die off when taking cuttings of this type or have they all died? If the latter, what might I have done wrong?
Thanks in advance,
Kean

 

Not sure Hibiscus is one of the easiest of subjects.
What kind is it?
The hardy garden plant or the indoor pot plant?

 

If it is a plant that is prone to wilt like that I would cover the pot & cuttings with a plastic bag - but it then needs to be out of direct sunlight otherwise it will cook!

 

It's an outdoor variety grown in a garden but more than that I don't know. I have plastic bagged them...perhaps the sun got on them and cooked them
Would you say that the fact that all the leaves have wilted means they are a lost cause or is it worth persevering for, what? a month? more? ...to see if they take?

 

Stress is best avoided in cuttings ... but I have had things lying around in a sponge bag for a week or more that have still rooted when I got home. Unless you need the space I'll give them the time to try. "It has two chances"

 

The outdoor ones are usually propagated by grafting I believe.
They are reasonably fast from seed, flowering in a couple of years if given good treatment.

If the leaves fall off the cutting it means the stem is still alive, if they stay attached then the wood is dead.

 

Thanks for replies
