Troubleshooting
Totem Pole Cactus problems — and how to fix them
Totem Pole Cactus (Lophocereus schottii 'Monstrosus') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Basal rot
Soft, browning tissue at the base from overwatering or a wet winter mix. Cut back to firm flesh, dry it well, and re-root the healthy upper column in gritty soil.
Etiolation and leaning
Pale, narrow, leaning columns indicate too little light. Move to direct sun to firm up new growth; the stretched section stays as is.
Fungal spotting
Brown or corky blemishes on the smooth flesh from humid, stagnant air. Improve ventilation, keep the body dry, and avoid wetting the column when watering.
Top-heavy toppling
Tall columns can lean or fall as they grow. Use a heavier pot or a discreet stake, and keep light even on all sides to encourage upright growth.
