Thanks, Rick! I've been using MSU and Orchid focus. I used to swear by Peters 20-20-20 for my African violets. I'll give it a whirl!
I use MSU with very good results for sanderianum growth too. But using oyster shell (also advocated by Rick H) helps retain the P in the mix which is otherwise in short supply in comparison between MSU and Peters formulas. It also supports the pH of the mix.
A dash of bone meal is also a good idea.
Anyway I don't think the type of fertilizer is as important as the air environment for these guys.
