The pot my Adenium was in broke. How do I replant this 10 lb plant? It's about 7-8 years old and has bloomed regularly. It has plenty of roots and multiple large sweet potato shaped (Caudex?) that were below the soil line. Should I separate these?

Beal,
They do not separate. It is one whole plant. Best to plant into another pot either the same size or a little larger, if the there was less than, say 1 1/2" on either side of base of plant and inside edges of the pot.
Not sure where you reside to have an idea on weather, temperature, etc.
Pot up using a free draining mix.
I do not want to get into a gritty mix as I use, because some ingredients may not be right on hand.
Use a Cactus mix with 2 Parts Cactus mix to 1 Part Perlite.

Let us know how things go and ask more of everyone if needed.

Thanks for the information, Rick. I've repotted using the cactus mix and perlite. Many leaves dropped off and now I'm watching for new growth.

We live in South Florida. The plant stays outside. I bring it in during Dec and Jan. We do get some cold nights here.
