Frequently Asked Questions
How much compost do I need for my garden?
For garden beds, spread 2-4 inches of compost. Calculate: (Length × Width × Depth in feet) ÷ 27 = cubic yards needed. A 10ft × 10ft bed with 3 inches (0.25 ft) depth needs: (10 × 10 × 0.25) ÷ 27 = 0.93 cubic yards.
What is the ideal carbon to nitrogen ratio for composting?
The ideal C:N ratio is 25-30:1. This balance provides enough nitrogen for microorganisms to break down carbon-rich materials efficiently. Ratios below 20:1 may smell bad, while ratios above 35:1 compost very slowly.
