Frequently Asked Questions

Why does my Cactus Totem Pole have a knobby, bumpy surface instead of ribs like other columnar cacti?

That knobby, "monstrose" form is a natural genetic mutation of Pachycereus schottii that suppresses normal ribbed growth — it's the defining feature of this cultivar, not a sign of ill health.

How much light does my Cactus Totem Pole need to keep its compact form?

At least 6 hours of bright, direct light daily. Insufficient light causes weak, pale, and unusually elongated growth instead of the dense, sculptural columns this cactus is prized for.
