Hi James!
to ATP!
We would love to see pictures of your adenium. Is it grafted? How old is it? Has it flowered yet? Inquiring minds want to know!
Tarev gave good advice about the media. Yes, well-aerated media is best for growing adeniums.
I live in the tropics and have my own preferred mix based on what is available.
Happy gardening!
