I have some small Norfolk pines that have been hit by frost. Will they come back? I also have one large Norfolk pine in the yard that is very tall and about 8yrs old. Will it come back after the frost has done damage? It has turned brown, but is the trunk alive?

From what I understand, if you scratch the bark with your thumbnail, just lightly and the cambium layer is still green, there is a chance the trees will live, but will not replace branches where they have died off! The tree will look quite gangly! Sorry, as they are beautiful trees!

Any plant with frost damage needs the area that's damaged removed from it, or it will take longer to heal. Then you must baby it back to health which can take quite a long time. (06/09/2007)
