Q.Adonidia (Christmas Tree Palm)
I recently planted a double trunk Adonidia (Christmas tree palm). We had a heavy wind and one of the trunks broke at the top of the tree taking off all of the palm fons off with it. The other trunk is perfectly fine. Will the trunk that broke grow palm fond back at the top of the tree or do I need to replace the whole tree?
So sorry your new palm suffered from this damage. The palm will not regrow top fronds.
I would have an Arborist that is familiar with palms determine if they can be separated.
