I recently moved into a house that has been vacant about a year and has what I believe are Christmas Palms out front. I was doing some yard work and actually tugged on one of the palm branches and the entire cluster of branches broke off of the trunk of one of the 3 trunks present. My question is, will it grow back or is it now a goner? I also have just started Scotts tree and shrub care to see if it takes care of the fungus that my palms have.
