I really like this cactus but I don't know what is wrong. It looks like a snow man. It started with two "balls" then grew another but the whole time it seemed like it was dead! The fourth "ball" came out then all of the four fell over (remained linked) and I can't find any roots. I had it in potting soil with 50% perlite. Does it need food? I very seldom water it. It gets full sun and all the other cactuses around it seem to be happy and thriving. Help!

I'm going to separate a segment, allow it to callous and then see if I can root it.

Interesting harmless-looking cactus with wide, papery spines. It develops in little pine-cone shaped segments and is very fragile at each segment, taking little effort to break off pieces at that point (had to blow leaves out of my cactus garden with a leaf blower and even that would end up blowing off segments of this species). Easy to propgate from the segments, though. I never could get one to grow very tall as they kept falling apart. Closely related to the much hardier pinecone cactus, which never seem to come apart at its segments. Note that though this plant seems relatively harmless- the large, flat spines are not all that fearsome... .the little fur-like spines at the base of these larger spines are quite a nuisance, and you should still use gloves to handle this plant.
