Saguaro finally thriving — the one thing that changed everything

I nearly gave up on Saguaro after three months of mediocre results. Then I focused properly on using pure mineral grit for drainage in the soil mix and within a few weeks the difference was dramatic.

It now lives in a greenhouse or conservatory staging and has genuinely transformed that spot. remarkable drought tolerance once established 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, using pure mineral grit for drainage in the soil mix is almost certainly the issue.
