⚠️ Potential Risks

Risks
  • Attracting pests: Fruit flies or other insects might be attracted to the sugary starter.
  • Slow decomposition if not properly incorporated: Large clumps might take longer to break down.
  • Potential odor if added in large quantities: It's best to add small amounts regularly.

💡 Best Practices

Best Practices
  • Add small amounts regularly: Avoid overwhelming the pile with large quantities of starter at once.
  • Mix well with other compost materials: This ensures proper aeration and decomposition.
  • Chop starter into smaller pieces (about ½ inch): This speeds up the decomposition process.
  • Consider burying starter slightly deeper within the pile: This minimizes odor and pest attraction.
