After severe winter only one frond has developed into branch. Is it possible that tree will recover fully. I am feeding it with tomato fertiliser. 1 Answers 0 Vote Up Vote Down Gerry Daly Staff answered 7 years ago With one leaf it may well recover, but it will take time. Do not give any feeding, except a mulch of rotted leafmould. Wrapping the stem with polythene might help to retain moisture.
