⚠️ Potential Risks

Risks
  • Pest attraction: Some herbs may attract pests if not properly incorporated into the compost pile.
  • Slow decomposition: Woody stems may take longer to break down than the leaves.
  • Disease transmission: If herbs were diseased, there is a small risk of spreading disease if not properly composted.

💡 Best Practices

Best Practices
  • Chop herbs into 1-inch pieces before adding them to the compost pile to speed up decomposition.
  • Mix herbs with a roughly equal amount of brown materials like dried leaves or shredded cardboard to maintain a balanced carbon-to-nitrogen ratio.
  • Ensure adequate moisture levels in your compost pile. If it's too dry, decomposition will slow.
  • Turn your compost regularly to improve aeration and promote decomposition.
