In-Ground Vermicomposting

Your own compost right in the ground – no smell, no trips to the compost heap

Most families keep a classic composter away from the house – and in winter, nobody feels like walking out to it. The in-ground worm composter works differently: you bury it up to the lid directly in a bed, greenhouse or large plant pot, and earthworms and microorganisms process the biowaste on their own, right on the spot.

The details that make the difference

No smell, no flies
The perforated walls let earthworms in and out and provide enough air – composting stays odourless.

Double benefit, there and back  
On their way into the composter, earthworms loosen the soil; on their way back, they leave valuable humus in the surrounding bed.

Year-round use 
No need to move the container for winter. When it's cold, earthworms burrow deeper into the soil or warm up near the decaying biowaste.

Recycled material 
The tall worm composter is made of 35 % recycled materials, the low one of at least 65 %.

Choose the tall or low worm composter

Tall In-Ground Worm Composter

For classic beds, raised beds and greenhouses. Volume 12 l.

Low In-Ground Worm Composter

For shallow raised beds and large plant pots where the tall one won't fit. Volume 7 l.

What goes in the worm composter – and what doesn't

Yes: vegetable and fruit trimmings and scraps, leftovers of boiled vegetables, paper tea bags, coffee grounds and coffee filters, crushed egg shells, dry bread broken into small pieces, remains of indoor and outdoor plants.

No: ginger, citrus fruits, chilli, garlic, dairy and meat products, bones, oil, lard and other fats.

Compost in a few months

Put chopped biowaste into the worm composter. If earthworms can reach it naturally from the surrounding soil, there's no need to add any. Where they don't occur naturally, add a starter culture directly onto the biowaste – 200–250 earthworms (500 g) for the tall and 100–150 earthworms (250 g) for the low worm composter. Add biowaste gradually so the earthworms have time to process it – don't overfeed them at first.

Tip: Cut larger pieces into smaller ones – earthworms will process them faster and you'll prevent mould.

Vermicomposting is for anyone who…

  • has a bed, raised bed, greenhouse or large plant pot and wants to process biowaste right on the spot

  • doesn't want to carry biowaste far from the house, especially in winter

  • wants their own compost and fertiliser without buying potting soil

  • is part of the zero waste community and wants to put biowaste to good use
