Q.A mature organ pipe cactus where limbs are starting to fall over
I have a mature old organ pipe cactus and in this last year many of the limbs are starting to fall over. Was wondering what can I do in this case? Is it normal for them to do this? Or do I have a problem such as over or under watering? thanks!

This actually sounds like a case of over-watering. These are very drought tolerant, and will not tolerate "wet feet" for very long. I would let the potting material dry out pretty well in between waterings. You might apply a few drops of rosemary oil in the water for the next watering, just in case an infection is trying to start in.
