Sterilizing Orchid Tools: Heat vs. Chemical Methods

Best Method: Heat Treatment

Pass cutting tools through a propane torch flame briefly. This kills viruses effectively.

When to Sterilize

• Every time you switch plants.
• Every cut if using same tool on multiple plants in one session.
• Viruses persist indefinitely on tools—daily sterilization isn't enough.

Chemical Alternatives

• Saturated sodium triphosphate solution.
• 10% bleach solution.
• Less practical; commercial growers prefer heat.

Why It Matters

Plant viruses (e.g., CymMV, ORSV) are invisible but spread via contaminated tools. Sterilization prevents cross-contamination.
