I got some of Hetty's cuttings in 2012 (Thanks Hetty). And I planted them just like I plant my succulents. Well draining soil, the cuttings are well calloused already when I got it. Like Hetty said you lose some, but the ones that remain will grow either leaves first or a bloom.
I have them in the sunniest side of my garden, and I water them thoroughly at least once a week and let dry. Our weather here is very dry too so it does not get too overwatered.
I have seen them being grown in Manila too with the tropical rainy weather there, but mostly in containers.
My mom in law initially had them in ground, but since they get torrential rains & the flash floods too, some of my mom in laws plants like that died. So they uprooted it from in ground planting and repotted to a container, so they can move it to a dry area when the typhoon season comes.
