I had three lovely Yucca trees in my front garden, but due to gales two years ago all leaves blew off and I was left with bare trunks. On advice given I left them until now to see if they would survive and grow again. There are lots of leaves growing around bottom of trees from the old roots. Can I just cut down the trunks now as they are dead. Any advice on how to do this would be appreciated.
