Peat‑Free Compost: What to Buy and How to Use It
Peat‑free compost is now the standard choice for gardeners worldwide, helping protect fragile peatland ecosystems. Modern blends perform just as well as peat-based mixes when used correctly. This expanded guide covers how to choose a good brand, how to use peat‑free compost effectively and how different climates influence performance across the UK, USA, Canada, Australia and New Zealand.
What Peat‑Free Compost Is Made From
Most peat‑free mixes include ingredients like:
- Composted bark for structure
- Coco coir for moisture retention
- Green compost for nutrients
- Wood fibre for drainage
- Leaf mould for water-holding capacity
How to Choose a Quality Mix
- Look for a soft, fine texture.
- Avoid overly woody or clumpy bags.
- Check for certification labels where available.
- Choose a blend suited to your climate.
Types of Peat‑Free Compost
Multipurpose
Works for most containers, beds and borders.
Seed‑Starting Mix
Fine and moisture-retentive; perfect for germination.
Potting Mix
Chunkier and longer-lasting, ideal for shrubs and perennials.
How to Use Peat‑Free Compost Effectively
- Add fertiliser after 4–6 weeks because peat‑free mixes are lower in nutrients.
- Water thoroughly during initial planting.
- Mix with compost or leaf mould to help structure.
- Store bags out of direct sun to prevent drying.
Climate Considerations
- UK: Choose moisture‑retentive blends for dry summers.
- USA: Hot states benefit from coir-rich blends.
- Canada: Bark‑rich mixes suit cool climates.
- Australia: Avoid overly fine mixes—they dry quickly.
- NZ: Most blends perform well all year due to mild seasons.
