Trouble propagating String of Pearls
I've read other threads about this issue but haven't been able to find any useful information. I recently took cuttings (strings of 3-4 "pearls") from a healthy mother plant. Per the instructions I found on the web, I half-buried them in some moist succulent soil, put the two 3" pots in a large ziploc bag and left the top open. I didn't water them for 2.5 weeks, but toward the end of that period I did occasionally mist them because the soil was bone-dry. At least one of the pearls survived in each pot, which I thought was a good sign, and I removed them from the bag and placed them in bright indirect light (which the bag was also in) and began to water 1x/week.
I discovered this morning that one of them had abruptly withered and died. That leaves me with one pearl in one pot, still alive but not rooting or growing so far as I can tell; I think it may be doomed as well. What am I doing wrong? Should I use a richer soil? Should the pearls be exposed to the air/light or buried more deeply? Thanks,
