  • Cover with 2.6 gallons of water (10 liters), ideally rainwater
  • Cover the bucket with an old cloth to let fermentation gases escape
  • Place your bucket outside, in the shade
  • Stir the liquid manure with a stick or a wooden spoon every day for 5 to 10 minutes
  • Let the wormwood steep for 10 to 15 days depending on the temperature. Fermentation is over when you no longer see bubbles or white foam rise to the surface
