Trachycarpus Fortunei

Help! My 60cm Trachy's leaves have gone all brown except in the middle.
I planted it in a pot last November and it was fine until late February. Is it possible that it is damage from frost and will it recover? It has 2 new spears which appear green so do I cut off the brown leaves and grit my teeth and put up with a scalped looking plant?
Many thanks.
