Hi Alberto, can I just clarify? You grow all your cyclamen and eg South African bulbs just in pots of pure granite grit with no other material (loam, grit sand, leaf mould etc) added? I assume you have to water and perhaps feed more often? And how do the 'woodland' species such as C. purpurascens or repandum cope with this regime? I'm intrigued, and will try this out for a few bulbs when I repot this summer to see what results I get. Regards, Steve.
