About 48% of our domestic waste could be used on our gardens. One way to do this is by using a worm farm. Composting worms are one of nature’s most efficient recyclers.
A worm farm is a container made up of plastic, wood or any other lightweight, waterproof material. You can buy a worm farm from a gardening or hardware store for less than $100 or make one. A worm farm is actually nothing more than a couple of boxes where your composting worms live.
MAKE YOUR OWN WORM FARM
What You Need
- 2 polystyrene boxes with lids the same size
- A strip of insect screen to fit into the bottom of the boxes
- Shredded newspaper
- A bucket of garden soil, or potting mix
- Food scraps
- 1000 composting worms (available from garden centres).
What To Do
- Take one box and make some holes in the lid and in the bottom of the box using a pen or screwdriver. Make your holes evenly spaced. The bigger the container, the more holes you will need.
- Spread the insect screen in the bottom, over the holes. This lets liquid through but stops the worms falling out.
- Fill your container about 3/4 full with shredded newspaper. Dampen your newspaper with water before you add it to the box. All the newspaper should be soaked through but there should not be extra water collecting in the bottom of the bin.
- Put some garden soil or potting mix in for grit. This will help your worms digest all the scraps you add to your bin.
- Add your worms to the container. Place the container with the worms over the second box, allowing the liquid to drain down into the second box. This liquid can then be applied directly to your plants.
- Add a small amount of food scraps to one corner, underneath some newspaper. See how long it takes your worms to break it down to understand how much your worms can handle at one time. Place your food scraps in a different spot each time.
- Lay a sheet of damp newspaper on top of the food scraps and keep a cover on your box. Worms like damp and dark. conditions so store your worm farm in a cool outdoor location, like a laundry, shed or garage.
