Welcome Val

If it hasn't woken up yet then now is the ideal time to move it. You can find fairly detailed instructions at http://www.ehow.co.uk/how_7647603_care-transplant-corkscrew-hazel-tree.html.

you have left it late as they are just starting into growth , if you do now make sure you dig up enough rootball and keep a eye on watering over the spring and summer and dont let it dry out , if me I would leave till late Autumn

I agree with GG would leave until late autumn now. Our corkscrew hazels already have catkins on them.
