Why are the leaves on my raspberry bushes shriveling up?

[alamahara]

I don't know what I'm doing wrong. They are wild raspberries which I dug up and transplanted from my Aunts land. I did this last year and they absolutely came up gloriously but now the leaf shriveling. Grrr..

I have them in full sun...is that the problem? I haven't fertilized them...could that be it?
