I have a Christmas cactus approximately 150 years old, it is about 3 feet across & 4 feet long. It hardly blooms anymore and is looking
spindly. It is a family heirloom & I don’t want to lose it. Have any suggestions?

It won't hurt it to cut the length back. You can make new plants with the cuttings. (I would cut it by half.) I'm guessing it hasn't been repotted in years. It could use some refreshed soil. It will be easier to repot if some of the length is cut off.
