Not all gardens have the space for a worm farm, but worms help to improve soil fertility in gardens and are a great way to keep your kitchen scraps out of landfill. So how can you reap the benefits of having worms in your garden without a worm farm? A worm tower is the answer! Take a look at the video for a step by step guide on making a worm tower for your garden!

  • A drill with an 8mm or bigger drill bit – plus safety protection of course!
  • Old sock 
  • Saw to cut the pipe
  • Texta for marking the pipe for cutting and drilling

Add some bedding made from a mix of dry grass or leaves, shredded paper or newspaper in the bottom of the pipe to create a nice safe home for the worms before adding in your kitchen waste. A sprinkle of water will help keep everything moist for the worms, and then pop the sock on the top of the pipe to keep any pests out.

What can be added to a worm tower?

Anything you would put into a worm farm can be put in a worm tower, but it is best to keep things chopped up fairly small. Along with kitchen scraps you can also add crushed egg shells, shredded newspaper or cardboard, grass clippings, and coffee grinds or tea bags.
