Hi, new here. Liking all the succulent pictures, especially the baby ones. We have a very mild climate here so just about everything succulent is (theoretically) possible outside. Including a pretty good variety of tree aloes.
I admire ambition but a couple of those tree aloes are really monstrous plants in nature (speaking of dichotoma/x and susannae) and it will be a real challenge to keep them going well in a small pot. That's a skill level way above my own, anyway. I have seen first hand the consequences when they get cranky. Total meltdown.
In my experience huge aloes are like huge agaves in that they are hard to keep thriving in pots.
Have you had these plants for a long time? How are you watering the dichotoma & hybrid?
