Comfrey Compost Accelerator Calculator
Comfrey is a powerful compost activator that can dramatically speed up decomposition and enrich your compost with nutrients. Use this calculator to determine how many comfrey plants you need to support your composting system.
Results
Note: These calculations are based on mature comfrey plants (2+ years old). New plants will produce less biomass in their first year.
How Comfrey Accelerates Composting
Nutrient Contribution
Comfrey leaves are exceptionally valuable in compost because they:
- Contain high levels of nitrogen, essential for microbial activity
- Break down quickly, releasing nutrients faster than woody materials
- Add potassium, phosphorus, and calcium to your finished compost
- Introduce beneficial microorganisms that aid decomposition
- Help maintain optimal carbon-to-nitrogen ratios
Application Method
For best results when using comfrey as a compost accelerator:
- Layer fresh comfrey leaves throughout your compost pile
- Chop or bruise leaves before adding to speed decomposition
- Add a new layer of comfrey each time you turn your compost
- Mix comfrey with both green and brown materials
- Consider making comfrey tea to activate stubborn compost piles
Comfrey Composting Tips
Layering Technique
Create thin layers of comfrey between your kitchen scraps and brown materials. This "lasagna" approach ensures even distribution of nutrients and activating compounds.
Hot Composting
For hot composting, add comfrey to the center of your pile where temperatures are highest. This accelerates the breakdown process and helps maintain higher temperatures.
Comfrey Concentrate
Create a comfrey concentrate by soaking chopped leaves in water for 1-2 weeks. Use this liquid to moisten dry compost piles and introduce beneficial microbes.
