Thanks for the input, all.
I'm going to try different mediums; more than one way to skin a cat, so to speak. *It seems the consensus is 50/50 peat and sand and if you error, error on the side of more sand (the right kind of sand, too). *This is what I've been doing lately, and they seem alright for now, but haven't had the plants long enough. *I repot every year anyway, anyway, thanks again.
p.s. more input is most welcome! !
