Moon Cactus finally thriving — the one thing that changed everything

I nearly gave up on Moon Cactus after three months of mediocre results. Then I focused properly on protecting from frost below -5°C even for hardy varieties and within a few weeks the difference was dramatic.

It now lives in a greenhouse or conservatory staging and has genuinely transformed that spot. architectural sculptural form that needs no flowers to impress is even more impressive in person than I expected from photos. complete dormancy in winter with no watering was spectacular — worth every bit of patience. If you're struggling with yours, protecting from frost below -5°C even for hardy varieties is almost certainly the issue.
