Hi Norman, From my experience no sinningia tuber does well in a cactus type mix, made up mainly of pumice and pea gravel. I use a 1-1-1 type mix made up of: 1 part of a good quality planting mix (Supersoil, Miracle-Gro, etc.) 1 part Perlite 1 part Peat Moss then I add 2-3 heaping tablespoons of crushed egg shells per quart (or litre) of this mix. A national authority on sinningias lives just a few miles up the road from you in Palo Alto. His name is Alan LaVerne and he is a big believer in using Supersoil only for all his sinningias. He does admit to a few failures with this mix though. He has a fun website to peruse, called Sinningias and friends. Try it at http://home.earthlink.net/~sinnvenner/sinns.htm He grows and does describe & discuss Sinningia aghensis.

After searching the web & viewing all the PBS archives I still have a couple questions. Should the soil be made up mostly of pumice & pea gravel and a little compost? Can it take full sun here in Z9 Northern California? I will have this in a pot can it survive outside in the winter or should it be kept inside and kept dry? thank you Norman Rose Z9 San Jose California _______________________________________________ pbs mailing list email@example.com http://www.pacificbulbsociety.org/list.php _____________________________________________________________ Netscape.
