Question 1

What is the ideal C:N ratio for composting?

Accepted Answer

The ideal ratio is 25:1 to 35:1, with 30:1 being optimal. Too much carbon (high ratio) slows decomposition, while too much nitrogen (low ratio) causes odors and nitrogen loss.

Question 2

How long does composting take?

Accepted Answer

Hot composting with proper management takes 2-3 months. Cold composting (minimal turning) takes 6-12 months. Vermicomposting with worms takes 2-4 months.

Question 3

Why does my compost smell bad?

Accepted Answer

Bad odors usually indicate too much nitrogen (greens) or poor aeration. Add more browns and turn the pile more frequently. Ammonia smell means nitrogen is escaping.

Question 4

Can I compost in winter?

Accepted Answer

Yes, but decomposition slows significantly below 40F. Keep the pile larger (at least 3x3x3 feet) and insulate with straw or leaves to maintain internal heat.
