Safety first

  • Wear nitrile gloves and eye protection and work in a ventilated area.
  • Use distilled water and clean glass equipment.
  • Keep chemicals and mixed solutions away from children, pets, food and natural waterways.
  • Do not consume treated flowers, seeds or plant material.

Materials

  • Two labelled glass mason jars
  • One glass spray bottle
  • One 50–100 mL syringe
  • Distilled water
  • 0.25 g silver nitrate
  • 2 g sodium thiosulfate pentahydrate
  • 2–3 drops mild dish soap

Prepare Jar A

  1. Add 250 mL distilled water to Jar A.
  2. Add 0.25 g silver nitrate.
  3. Seal and gently swirl until fully dissolved.
  4. Protect the jar from light.

Prepare Jar B

  1. Add 250 mL distilled water to Jar B.
  2. Add 2 g sodium thiosulfate pentahydrate.
  3. Seal and gently swirl until fully dissolved.

Make the 50/50 concentrate

  1. Draw the required amount from Jar B first.
  2. Transfer Jar B solution to a clean glass mixing container.
  3. Rinse the syringe thoroughly with distilled water.
  4. Draw an equal amount from Jar A.
  5. Always add Jar A into Jar B while gently swirling.
  6. The finished concentrate should remain clear. If it turns black or grey, discard it and restart.

Dilute for spraying

Mix at a 1:9 ratio: one part 50/50 concentrate to nine parts distilled water. Add 2–3 drops of mild dish soap to the final spray solution.

Final spray Concentrate Distilled water
100 mL 10 mL 90 mL
250 mL 25 mL 225 mL
500 mL 50 mL 450 mL
1 L 100 mL 900 mL

Application schedule

  1. Select the branch or plant intended for reversal.
  2. Begin spraying a few days before flowering starts.
  3. Wet the selected area evenly without allowing it to drip.
  4. Repeat every 3–5 days for approximately 2–3 weeks.
  5. Stop once pollen sacs begin to form.

Storage

Store Jar A, Jar B and diluted spray in sealed glass containers, protected from light, in the back of the refrigerator. Label every container clearly.

  • Jar A and Jar B concentrates: approximately 5–6 months.
  • Diluted spray solution: approximately 1–2 months.

Cleanup and disposal

Rinse the syringe and reusable glass equipment immediately with plenty of cold water. Do not pour concentrated silver-containing solution onto soil, into drains or into natural waterways. Collect unwanted concentrate or spray in a clearly labelled sealed container and follow local household hazardous-waste requirements.

Keep treated plants or branches clearly identified and separate from material intended for consumption.
