do they fall off with juice in them or shriveled up. i grow some sort of graptopetalum outside and every spring when you would think they would be doing better the under leaves turn yellow and mushy and rot on the stem. a few weeks later its covered in new shoots where the leaves where.
Long story short if the growing zone looks good and the stem isnt to long ie top heavy it probably doesnt matter.
try to use fast drying soil and only water when it is sunny. If they are inside the house and you heat it then water them a bit more. you want real fast draining soil so you can water them more AND let them dry more. they like lots of water when they are growing but still less then a normal houseplant. also dose the tray under it have standing water that is bad. and water it so the water drains through a bunch like a small stream of water draining not just drips.
good luck
