Tarev,
That's very interesting. I like the idea of the orchid bark or chips because withal, I'm looking at this plant's root mass, and it's apparent that it's asking too much of it to expect it to hold the relatively massive plant upright. BUT, if those roots could bind to something, orchid-style, it might be a different story -- and intuitively, they are more likely to bind to something organic than to the pebbles i had in mind.
Just a thought - I might also be able to re-purpose some of that fibrous orchid medium and add it to the mix. What that stuff brings to the party -- maybe -- is a way to get the whole medium to bind together, something that's sorely lacking in the crumbly mess I have now.
Thanks again.

Try if this would work better for you. They are epiphytic cacti, so I kind of treat them like I am growing terrestrial orchids.
