It is an adonidia merrillii and it was hit with frost. The center is very brown and I pulled gently on a center frond , it started to come out and I saw some very very small white worms. It looks rotted. It has two trunks and the one trunk looks very good and fronds growing. It does have two small fronds on the side of the center and they are green but not growing. Please advise what to do to nurse it back or is it to late.
