Not possible, I'm afraid - you will have to wait and see if it recovers - if no growth by mid april, you can try cutting the main stem down by half to see if that forces growth from the base or up the remaining stem.

I have three cordylines which have suffered from the frosts of the very severe winter. Yesterday I asked the advice of an authority on homoeopathic plant care. On his recommendation I have given a homoeopathic remedy called Carbo veg in the 6x potency. This remedy is possibly available OTC but if not then certainly from a homoeopathic pharmacy - Helios or Ainsworths. I would think approx £5.00. A pillule [pill] should be put into a jug of water and poured onto the soil around the base of the plant. I only this did this yesterday but the leaves have already 'lifted'. Now, I just have to wait... At very little cost it is worth trying.

ALSO for information: I often use the Bach flower 'Rescue Remedy' when any plant looks in need of some rescue i.e. when moved ... and the roots have been disturbed... google Bach flower remedies for more information.
