Plumies are funny. They seem to do better with benign neglect than TLC...am learning to adapt.
I use a mix of 1/2 perlite, 1/2 cactus/palm mix, and mix some aquarium gravel into that, to give the soil enough holding power to keep my cuttings upright. I still use small landscape river rocks on top of the soil for support, and stake the cuttings after they have leaves, but am careful not to hit the roots when adding the stakes.
I wish you better success with your next cutting, Bearsearch, or you can always do what I do, to hedge my bets. I also grow seedlings:) Keeps me occupied, but mostly, it keeps me from killing my cuttings with too much care.
