Every compost reviewed here has been independently benchmarked using the Multipurpose Compost Balanced Scorecard (v9.2e) — a structured system that evaluates ease of use, composition, and sustainability.
Scores are data-driven, not sponsored. Each review combines measured performance with practical gardener feedback, helping you choose the right mix for containers, raised beds, or soil improvement. Peat-free, digestate, coir, and PAS100 composts are all compared on a consistent 1–10 scale
