Yes, thank you for posting the link.
I had read this PDF when I first started growing from seed. And two years later (and having learned much more about growing adeniums), in re-reading this PDF I discovered so many contradictions and inconsistencies. The most conspicuous one is contained in the last paragraph:
"Personally I just start out with a permanent 12 inch 2 gallon plastic container, permanent, uncompressible media and don’t repot until the container begins to fail from old age. I want as large of a single fat caudex as possible. I’ll typically repot into a 15 inch diameter 3 gallon container. Anything larger than 3 gallons is just too heavy for my bad back to handle. If the Desert Rose gets really large and requires a large container I switch the potting media to one based on perlite."
Edited to say this is just one person's take on how to grow adeniums in Florida.
