1. Rehydrate: Place your coir block in a bucket or trug. Add around 3–4 litres of warm water per block.
2. Wait 10 minutes: The block will swell into a soft, crumbly compost.
3. Fluff it up: Break apart any dense patches to create a light, even texture.
4. Use as needed: Perfect for worm bedding, seed sowing, or mixing into garden compost.

Wiggly Tip: You can speed things up by using warm water and stirring halfway through the soak.

At Lower Blakemere Farm in Herefordshire, we’ve used coir for decades as a clean, peat-free base for wormeries and composting. It’s gentle on worms, safe for seedlings, and perfect for balancing the nutrient-rich castings produced on the farm.

When you buy Wiggly Coir Blocks, you’re not just buying a compost base — you’re backing regenerative British farming that feeds soil life, not landfill.

For Potting Compost (general use):

• 2 parts coir
• 1 part worm casts
• Optional: handful of sharp sand or grit for drainage

For Seed Compost:

• 3 parts coir
• 1 part worm casts
• Mix thoroughly and sieve for a fine, even texture
• Perfect for trays, plugs, or propagation

For Top-Dressing Plants:

• 1 part coir
• 1 part finished compost or worm casts
• Sprinkle a 1–2 cm layer on top of pots or beds to retain moisture and feed microbes

Coir + worm casts = the perfect balance of structure + life. The coir aerates and holds moisture; the worm casts deliver nutrients, beneficial microbes, and natural growth hormones.

Wiggly Tip: Worm casts alone can be too rich for seedlings — mixing with coir dilutes and balances the biology.

🌿 Mulch: Keeps soil moist, suppresses weeds, and improves texture over time.
🪴 Houseplants: Add to indoor plant soil for better drainage and aeration.
🐛 Compost Booster: Lightens heavy compost heaps and speeds up decomposition.
🌾 Seedling Support: Ideal for rooting cuttings and growing microgreens.

Alternatives like Wiggly Woolch (raw wool mulch) or leaf mould also complement coir, adding structure, nutrients, and soil carbon — perfect for gardeners who want to go fully peat-free.

Why Worms & Coir Are a Perfect Match

Worms love the texture and moisture of coir — it’s gentle on their skin and full of air pockets. When mixed into their bedding, it prevents compaction, reduces odours, and encourages even feeding.
Combined with our Rock Dust or Lime Mix, it creates the ideal living environment for composting worms to thrive and multiply.
