I had a D. dielsiana that was getting overcome by moss and a D. capensis that was looking very peaked under some lights, so I moved them both to a southern window. *I replanted them into some bowls (those plastic ones you can get here, as a matter of fact).
The D. dielsiana, after I plucked all the moss away from the clump, has sprouted a bunch of new leaves--it's as if I have six new plants!
But the amazing one is the D. capensis. *I clipped off the "growth points" (rosettes?), and planted those in the new soil. *I then planted the rest of the plant with one "stem" exposed vertically and the other planted horizontally just under the soil surface. *One of the growth points sprouted new leaves and roots. *I have two new points on the old stem, and the buried one is producing new shoots all along itself!
And the dried LFS I used as a top dressing is coming to life in spots. *There seems to be some sort of grass springing up in there, as well. *I'm leaving everything alone except the original killer moss, which I continue to pluck out as soon as it appears.
The sun really makes a difference. *Accept no substitutes. *Experiences like this are almost enough to make me believe in spontaneous generation!
