Low-effort approach to Moon Cactus — what you can get away with

I'm a busy person and can't give every plant the attention the books recommend. Here's what I've learned about the minimum viable care for Moon Cactus.

using pure mineral grit for drainage in the soil mix is genuinely non-negotiable — skip this and the plant declines noticeably. Everything else, I've found, has more tolerance than expected. spider mites in warm dry indoor conditions will happen if you're inattentive for too long — check occasionally and deal with it quickly. spectacular but brief blooms that can appear overnight holds up even with fairly basic care. a grouped desert landscape display has been good because it suits the plant's needs without me having to compensate with extra intervention. A plant for real life, not ideal conditions.
