well good golly!
Now I understand why I've lost so many!
What I have available are perlite, vermiculite, orchid bark chips, and aquarium gravel.
Plus the miracle grow regular potting soil and a lot of rather peaty topsoil, which is what I use in my outdoor containers.
It sounds like I should treat sedum and delosperma more like an orchid than a plant that can grow in the ground.
SOME sedum grow well in the ground for me so I never thought to go SO dry with them....
Should I bring the delosperma indoors for the winter?
