Whether you're a seasoned green thumb or just getting started with sustainable gardening, a wormery is one of the simplest and most effective ways to turn household waste into gardening gold. Compact, efficient, and surprisingly low maintenance, wormeries are a fantastic addition to any outdoor (or even indoor) space.
So, what exactly is a wormery, and why should you consider having one in your garden?
What is a Wormery?
A wormery is a contained composting system that uses special composting worms — typically tiger worms or red wigglers — to break down organic waste. Unlike traditional compost heaps, wormeries work faster, take up less space, and produce two amazing by-products:
-
Vermicompost (worm castings): a rich, crumbly compost full of nutrients and beneficial microbes.
-
Worm tea (leachate): a natural, concentrated liquid fertiliser that can be diluted and used to feed your plants.
The Benefits of Using a Wormery
1. Reduce Household Waste
A wormery can dramatically reduce the amount of kitchen and garden waste you send to landfill. Fruit and veg peelings, tea bags, coffee grounds, and even shredded paper can all be repurposed into valuable compost.
2. Improve Soil Health
Worm compost is packed with nutrients and natural enzymes that help improve soil structure and plant health. It’s a fantastic organic alternative to shop-bought fertilisers.
3. Compact & Convenient
Don’t have a huge garden? No problem. Wormeries are compact and ideal for patios, balconies, or small gardens. You can even keep them in a shed, garage, or under a kitchen sink — they’re odour-free when managed correctly.
4. Great for Kids & Beginners
Setting up and maintaining a wormery is a brilliant educational project for children and a satisfying introduction to composting for adults. It's hands-on, eco-friendly, and endlessly fascinating.
5. Liquid Plant Food On Tap
One of the perks of owning a wormery is the steady supply of "worm tea" — a liquid fertiliser that can be diluted (usually 1 part worm tea to 10 parts water) and used to feed houseplants, veggies, or flowerbeds.

Top Tips for Wormery Success
-
Keep it moist, not soggy – worms like a damp bedding environment.
-
Feed gradually – especially at first. Let your worm population grow into the waste you're adding.
-
Use bedding – shredded cardboard, paper, and coconut coir make great bedding to help balance moisture and airflow.
-
Temperature matters – worms prefer temperatures between 15–25°C. Keep your wormery out of direct sun and protect it from frost in winter.
