I wouldn't want to try the plunge cut, even on a palm. You cut a few oaks like that, and the tip of your bar will be wore out.
I do have about fifty palms growing in an old plastic swimming pool. I cut one of the big tags of seed off into the canoe one day on the river. I had the pool with some dirt in, so I tossed the seeds in and covered them up. Most all of them came up. They are just over ten years old and almost waist high. If I live long enough, I might see them get head high.
