Turn smelly, slimy grass piles into rich, healthy compost — fast.
Wiggly Complete Rot is the natural, farm-proven compost accelerator that balances nitrogen-heavy grass clippings, boosts microbial life, and gets air back into your heap.

Formulated on our regenerative farm in Herefordshire, this mix contains natural minerals, microbial activators, and carbon-balancing ingredients that transform lawn waste into sweet-smelling, nutrient-rich compost.
Perfect for gardeners, allotments, and farms that want to cut methane emissions, reduce waste, and build soil health.

Key Benefits

⚡ Speeds Up Decomposition: Converts wet grass clippings into usable compost up to 3× faster.
🚫 Prevents Slimy Rot: Promotes aerobic activity — no smell, no sludge, just crumbly compost.
🌎 Reduces Greenhouse Gases: Aerobic breakdown releases CO₂ instead of methane.
🌿 Improves Soil Fertility: Creates humus that boosts structure, drainage, and microbial life.
✅ Safe & Sustainable: 100% natural, peat-free, and safe for organic gardeners.

We didn’t invent this in a lab.

We made it because we needed it.

At Lower Blakemere Farm, we deal with:

  • Grass
  • Straw
  • Manure
  • Real volumes of organic waste

This is what we use to turn it into compost that feeds our soil.

Now you can do the same in your garden.

When grass rots badly:

  • It releases methane (a powerful greenhouse gas)
  • It wastes nutrients
  • It creates pollution, not soil

When it composts properly:

  • Carbon is locked into soil
  • Microbial life explodes
  • Soil structure improves

👉 This isn’t just composting
👉 This is soil building

Good composting needs:

  • Carbon : Nitrogen → ~25–30:1
  • Oxygen
  • Moisture
  • Microbial life

Grass alone fails on all of these.

Complete Rot fixes all four.

  1. Add grass (10–15cm layer)
  2. Sprinkle a handful (150–200g per wheelbarrow)
  3. Add browns if you have them
  4. Turn weekly

That’s it.

👉 Within weeks:

  • Heat builds
  • Smell disappears
  • Structure improves

💬 Does It Smell?

No.

It prevents smell.

If your heap smells:

  • It’s gone anaerobic
  • This fixes it

🐛 Can I Use It With Worms?

Yes — and it works brilliantly.

👉 Let the heap cool below 25°C
👉 Then add worms

You’ll get:

  • Faster breakdown
  • Better compost
  • More microbial life

❓ FAQs

Do I need browns as well?
Helpful, but not essential — this replaces the need in most cases

Can I use it in any composter?
Yes — bins, heaps, tumblers

Is it organic?
Natural ingredients, peat-free, soil-safe

How long does it take?
4–6 weeks to active compost

🌿 Wiggly Tips

✔ Don’t dump thick grass layers — always mix
✔ Keep it like a wrung-out sponge
✔ Add Bokashi for a serious boost
✔ Add worms at the end stage

What our customers say

Brilliant live worms and great service! I ordered a batch of live composting worms for my new wormery, and they arrived in perfect condition — lively, healthy, and ready to get to work straight away. The packaging was eco-friendly, and the team even included a little guide on how to settle them in. My kitchen scraps are disappearing fast, and I’ve already started harvesting my first bit of worm compost. Couldn’t be happier!

Fantastic bokashi composting advice As a complete beginner to bokashi composting, I really appreciated how helpful the team were. They answered all my questions quickly and gave me simple, clear instructions to get started. The bokashi bran is top quality and smells fresh and pleasant. After just a few weeks, I’ve turned my kitchen waste into brilliant compost-ready material with no odour or mess. Highly recommended!
James T.
Top-notch British birdseed mix The British birdseed from Wigglys is superb. It attracts a lovely variety of garden birds — robins, finches, and even a pair of goldfinches have started visiting regularly. You can tell it’s a quality mix with no fillers or dust. Delivery was quick, and everything was packaged sustainably. It’s become my go-to source for bird feed!
