Hello,
A few months ago, I got some SA succulent Pelargoniums and Sarcocaulons. Can any of you tell me which of these are summer and which are winter growers. And when should I slow the watering or does the plant tell me by dropping leaves? Any other information on how to grow them would be appreciated. I do have them in a very gravely soil mix in small pots. I have shelves on my back deck (S. exposure) with a 40 shade cloth over it where they could go and the day-high temperature in summer will be around 90F (32-33C). Will this trigger dormancy in the winter growers? I also have a patio greenhouse in which the day-high temps get to mid-90's (35-36C). It has polycarbonate covering (open front and vent) and a shade cloth as well. Currently they are in a sunroom with day-high temps around 85 (29C). My location is in my previous post.
Sarcocaulon crassicaule
S. herrei
S. vanderietiae
Pelargonium alternans
P. paniculatum
P. spinosum
Hi Anna, The attached link maybe useful to you as it contains climate data for the town of Calvinia (NW Cape) which is representative for the natural habitat of your plants. Regards
Every little bit of info does help and it looks like a very useful site. So far they're doing ok, the stems are firm but few or no leaves so they do look semi-dormant (except S. vanderietiae, which is currently in full growth). Maybe they're influenced by daylength. They are outside but protected from rain, which can come an inch (25 mm) in a single downpour here.
