Husbandry & Evidence Review – 6 September 2026
This article’s original premise was incorrect and potentially unsafe: carbon dioxide exposure is not sterilisation and concentrated CO₂ presents an asphyxiation hazard. The step-by-step CO₂ procedure has been removed.
Correction: exposing branches, leaves or substrate to carbon dioxide does not sterilise them. CO₂ may kill some air-breathing hitchhikers if exposure is sufficient, but it does not reliably eliminate bacteria, fungi, spores, parasites, eggs or chemical contaminants.
Safer preparation approach
Use positively identified materials from low-risk sources. Remove soil/debris where appropriate, rinse and physically inspect, then quarantine/observe before use. Heat treatment may be appropriate for some materials, but fire risk and material damage must be managed. If a diagnosed pathogen or significant chemical contamination is suspected, discarding the material may be safer than attempting home decontamination.
Human safety: concentrated CO₂ is an asphyxiant. Frogfather no longer recommends sealing materials with CO₂ as a home “sterilisation” procedure.
