@gijsje Good question! I have absolutely no idea. Cacti just kinda come to me. I tend to pick up cactus limbs whenever I see them on the ground when I go for walks. Cacti are so easy to propagate...all you need to do is stick them in the ground and they grow. They are also notoriously weak...they break a lot and fall all over, but it's their nature to do that 'cuz that's how a lot of them spread.
i have a windowsill full of cacti and succulents now, and overflow in the greenhouse, my problem is they get too waterlogged outside in our climate over winter so i cant just put them outdoors and i am running out of space!
