⚠️ Potential Risks

Risks
  • Oxalic acid in high concentrations can inhibit decomposition and potentially harm beneficial compost microbes.
  • The leaves' large size may slow down breakdown if not properly chopped.
  • Adding too many rhubarb leaves at once could create an overly wet and nitrogen-rich environment, attracting pests or leading to foul odors.

💡 Best Practices

Best Practices
  • Chop rhubarb leaves into 1-inch pieces before adding them to your compost pile.
  • Mix the chopped leaves thoroughly with brown materials (such as dried leaves, straw, or shredded paper) to maintain a balanced carbon-to-nitrogen ratio.
  • Add rhubarb leaves in small quantities to avoid creating an overly wet environment.
  • Ensure adequate aeration within your compost pile to prevent anaerobic conditions that might lead to foul odors.
