bathroom placement on Echinocactus
Quick answer
If your Echinocactus has bathroom placement, the most likely cause is: Bathrooms have relative humidity of 60-100%, far exceeding the 30-50% range that desert cacti require. Prolonged humidity exposure causes the cuticle to soften, making the plant susceptible to fungal invasion and basal rot. Condensation on cactus surfaces creates a micro-environment for Botrytis cinerea and Erwinia infections.
Start here:
- 1. Remove cactus from bathroom immediately if any soft spots, discoloration, or mold appear on the surface
- 2. Allow the cactus to dry in a well-ventilated area for 48-72 hours
