Propagating Sans. If you have a colored and/or variegated plant, you'll need some of the root to keep the colors. If it is a plain green plant, you can do a leaf cutting. You can even cut that leaf into smaller pieces if it is long to begin with. And, here's the part you may not know - upside down does not work. Those leaves/cuttings must be planted right side up. After, of course, letting the ends dry out, say 2 week on a shelf. So, when I do make cuttings I make up a label for that species and it will remind me which way is up. S. Schwieinfurthii in this case. I'll add some previously posted pix of S. Cylindrica pups. Each leaf/cutting sometimes puts out more than one new plant. Gene
