I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
The brown fronds do protect the tree but very little. If your husband doesn't like the look then you can go ahead and remove them back to the trunk. However if all the fronds are brown this is not a good sign and the tree's top may have been killed in which case it will not recover. Time and warm weather will tell whether or not it will come back.
Thanks for the question. Please stop in again soon!
