Are you saying that you had spear pull on 2 out of the three palms in a grouping? Even if you did, all is NOT lost. Phoenix roebellini can recuperate from the loss of the central spear. Mine did from cold damage three winters ago. The first summer after the damage it was stunted for most of the growing season--didn't do a thing. Then it started to grow a bit in September and October of the same summer--having developed a new central spear bud. The second summer it not only took off, it flowered. This summer it is flowering again and is growing vigorously! Yes, it will be stunted but probably NOT dead. Be patient in the meantime.
