Whether you're a seasoned cactus enthusiast or just growing a few plants on the window sill you'll probably find that at some stage you'll want to get together and talk to like minded people. That's where the British Cactus and Succulent Society comes in.  There are branches all over the country that have regular meetings. It doesn't cost much for membership (£20 for full membership, less for concessions) There is a quarterly magazine (Cactus World) and, as if that wasn't enough for the bargain price, there is also an annual seed distribution where you can buy excess seed from other members for a very reasonable price.
