Worm farms

Worm farms are ideal for small spaces and take a range of food scraps. They are also great educational tools for kids to learn about the environment.

A worm farm is a fantastic way to turn your organic waste into nutrient-rich fertiliser for your plants and soils. Worms eat organic waste and turn it into worm castings (the organic material that has been digested by the worms) and a small amount of liquid. Both of these products can be used on your garden to help your plants thrive.

How do I get started?

Get a worm farm

Find a cool shady spot to locate it. Bayside City Council has worm farms and worms available for purchase at discount prices for residents.

Create a bed for your worms

Your worms will need a bed inside their box. The bed should be made out of good-quality soil, leaves and shredded paper. The worm bed should be around 15cm deep. Add a little water to the bed, it needs to be kept moist but not wet.

Add some worms

Gently add worms to your worm farm and watch them burrow in. You should wait at least 24 hours before feeding them to allow them time to get used to get used to their new surroundings.

Feed your worms

Add your kitchen waste regularly in small amounts. Cover new food with a light layer of bedding material or a handful of soil or compost.

Harvest worm liquid and castings

As the worms eat your kitchen scraps, they will produce castings that will drop to the bottom of the unit. To collect the worms castings, simply lift the tray up in order to access them. You can use your castings to improve soil quality and for fertilising around plants. Worms also produce a liquid, which can be drained off using the tap at the base of your worm farm. Make sure you dilute it with 4 parts water to 1 part liquid before use.
