You would literally have to hang it where no one could even come close to getting under it. Perhaps in a fenced in area or the like. When I lived on the MS coast, mine got over 100 lbs. and I just couldn't move it any longer. I think I ended up cutting it into a dozen, nice-size chunks and got lots of basal frond fiber when I reduced all those cuttings' thickness. I don't think that fiber (I'm sure there must be a name for it) will ever rot. After 25 years, I still have some of that same fiber and still use it when mounting.
