The Amateur’s Digest has some interesting information about cacti and succulents. For instance, here we have an article about Ceraria namaquensis, a plant that we grow but have had trouble rooting, and right there is some advice that we might have to try out.
This year I have been using commercial peat blocks for rooting more difficult items such as rarer euphorbias, Madagascan thorn bushes and stems of Pachypodium succulentum. While I was at it I put some of the ‘unrootable’ stems of C. namaquensis into the blocks. The cuttings survived well in the moist peat blocks and after about three months began to root and grow.
