Hope this is helpful Patti. Twitcher has a very interesting way of seeing how things work, kind of a scientifical way of explaining. Have fun reading.

Thank you so much! That's more than I found. 😃

Hope the links were helpful.
There are so many different mixes, depending on growing conditions. For succulents the main thing to remember is fast draining. And it helps to research where the plant originates from, what type of soil are they growing in, in the wild?
