Starting a wormery at home in the UK is one of the easiest ways to reduce food waste and create nutrient-rich compost for your garden. It’s simple, low maintenance and works even if you only have a small space.
This beginner-friendly guide shows you exactly how to set one up, what worms need to thrive, and how to avoid the most common mistakes.
What is a wormery?
A wormery is a compost system that uses worms to break down kitchen waste. This process is called vermicomposting. The worms produce a rich natural fertiliser known as worm castings.
Best worms for a wormery
Not all worms are suitable. You need composting worms, not garden earthworms.
- Tiger worms
- Red wigglers
- Dendrobaena worms
These species live near the surface and eat organic waste efficiently.
What you need to start
- A worm bin or stackable wormery
- Composting worms
- Shredded cardboard or newspaper
- Kitchen scraps
- Spray bottle with water
Setting up your wormery
Step 1: Prepare bedding
Shred cardboard or newspaper. Dampen it slightly so it feels like a wrung-out sponge.
Step 2: Add worms
Place worms on top of the bedding. They will burrow down naturally.
Step 3: Feed lightly
Add a small amount of food waste. Bury it under bedding.
Step 4: Keep it dark
Worms dislike light. Keep the lid on.
