One of the links I came up with said whatever Aloe that might be a match for it, is very hard to grow. However, I got a cutting started before that (under different circumstances) which is doing very well, branching out into more florets for my sister-in-law. That cutting had fallen out of sight & I didn't know where it was for a very long time. When I found it, it seemed totally dry & dead, but since I had some moist soil in an empty pot, I stuck it in . . . and one week later was surprised that it had become green . . . & one more week past indicated roots were forming! I re-potted it into a mix of store-bought potting soil, & soil from my yard. . .
The cuttings in question, however, I allowed to heal for no more than 3-4 weeks, and then used ONLY store-bought potting soil ... Could that be the problem? I seem to recall reading an article on this site about Aloes requiring a certain bacteria (or, fungi?) in the soil in order to do well.
