The whole point of so many posts on gritty mix on this forum is to grow succulents in them, so the answer to your query is a qualified yes - qualified because (1) while I wouldn't use bark at all in it, many do (2) I don't believe any Lithops would grow well in a barkful gritty mix.

I know they are grown in a gritty mix, but if I just said 'gritty mix' there are so many different mixes, including cactus soil, pumice, granite, perlite, and turface. I was mainly wondering whether MY gritty mix (the one in the OP) was sufficient ( I can't quite tell, but I think you got that). I am flexible on bark amounts and ratios of ingredients, though.

Thanks for the reply!

They'll grow in almost anything, so if you assemble a mix as a test and run water through it, and it drains well, I'd say that's a ratio to use. Maybe make like photography and use the Rule of Thirds. I don't know for sure, as as I wrote I don't use bark. For me, my 40/40/20 (Turface/granite grit/sieved soil) works well.

Jade will grow easily in your standard gritty mix. Many succulents will.

Lithops are tricky in any mix, at least for me, so can't really advise on that one.

Thanks for the reply! I was pretty sure they would be able to at least survive, but I really wanted some more input!
