Hi azponder,

I'm not sure what species that is, but I've had the same problem. (Tonight it's *snowing* here!) A few people were quite helpful with my questions, so maybe one of them will answer your post, too.

Until then maybe this will help -

When the cactus here keeled over I got some cardboard to prop them up with. The cactus without any pads just got a long triangle shape of cardboard wrapped all around it and held in place at the bottom with rocks. The prickly pear type cactus with pads was a bit trickier.

I placed a little cardboard under the cactus pads and then stuck tree branches (which I cut into a Y shape with the very long bottom part of the Y being stuck in the ground and the "V" part of the Y propped under the cactus) under that. The cardboard was so the branch/prop won't poke into the cactus pad.

I'd just pruned those tree branches, but luckily they are strong enough to use to prop up our cactus. (Cactii?)

It's not a long-term solution, but maybe one you can try it with a few of your cactus "branches" that are closer to the main body of the cactus? You might have to cut off the ones that were frozen. I did with the ones that got frozen and mushy before we got proper 'freeze fabric' to cover everything with.

You might want to check out the thread where I was asking for help with my cactus, here -

Good luck with everything :)
