Our Wiggly Coir Blocks (also known as coco coir bricks or coconut fibre blocks) are a simple, reliable way to create a peat-free growing medium for composting, wormeries, seed sowing, and soil improvement.
Each compressed coir block expands with water to produce around 9 litres of soft, airy, moisture-balanced material.
But this isn’t just a coir block.
It’s what makes wormeries work properly, compost behave, and soil improve.
🌱 WHAT IT ACTUALLY DOES
Coir isn’t about feeding plants directly — it’s about structure.
It:
-
holds moisture without becoming waterlogged
-
creates air pockets for worms and beneficial microbes
-
prevents compost turning dense, claggy or smelly
-
improves drainage while still retaining water
-
balances rich materials like worm casts and compost
If your compost is too wet, too compact, or lacking structure — coir fixes it.

⚖️ IS THIS JUST A STANDARD COIR BLOCK?
Yes — coir is a natural coconut fibre product.
But not all coir is used in the same way.
This coir is:
-
suitable for composting and wormery systems
-
untreated and safe for soil biology
-
used on a working farm in real compost systems
If you just need a basic potting material, standard coir will work.
If you are composting, keeping worms, or improving soil — this is where coir becomes far more valuable.

Starting a wormery → 1 blocks

Refreshing a wormery → ½ to 1 block
-
Mixing compost → 1 block per batch
-
Seed sowing → 1 block goes a long way
🌍 WHY CHOOSE COIR OVER PEAT
Peatlands are important carbon stores, but traditional compost production has damaged them over time.
Coir offers a peat-free alternative.
It is made from coconut husk fibre — a by-product of the food industry — and provides:
