Worm Castle FAQ
Where can I buy the Worm Castle?

I live outside Australia. How can I purchase a Worm Castle?
Contact us and we can arrange that for you.
How many worms do I need to start my Worm Castle?
The Worm Castle can hold 4-5000 worms, but we normally recommend that you start with 1000.
Where can I buy compost worms?
Most of our retailers can provide you with compost worms. Check out your local suppliers and worm farmers.
How long will it take for my Worm Castle to be ready for harvest?
It depends on the size of your household, diet and how many worms you start with. However, as a rule of thumb, it will take 2-3 months to add each tray, so you’ll be able to harvest after 6-9 months. For more information, see our worm farming advice pages.
Do you provide after-sales service for the Worm Castle?
Yes, we do. Please contact us via this link if you have any questions, and please consider joining your local Worm Farming Advice Facebook group for free support.
How many trays are there?
There are three working trays that rest on top of the liquid tray. This number is ideal to ensure that the castings in the bottom tray are ready to harvest when the top tray is full.
Why are the legs so short?
The Worm Castle legs are designed to be tall enough to fit an ice-cream container under the tap, but not so tall that they break or the worm farm topples over.
Should I add dirt to my worm farm?
No. Unlike earthworms, compost worms do not eat dirt. Instead, they eat decaying organic material like grass clippings and food scraps and convert this into worm castings.
What should I feed my compost worms?
Compost worms will eat a large variety of organic materials like bark, leaves and food waste. For a complete list, click here.
Why do I need a worm blanket?
A worm blanket provides a thick layer of insulation that helps keep the worms in their safe growing temperature between 20 – 30 degrees C (depending on the variety). Worm blankets also help keep moisture in your Worm Castle, reducing the incentive for worms to crawl out of the bedding and on to the inside of the lid and walls of your worm farm.
Lastly, a worm blanket can act as a backup food source if you forget to feed your compost worms or are away on a holiday. The worms will be able to eat the jute fibre as a last resort, keeping them going until you next feed them.
What are Worm Castle worm blankets made of?
Worm Castle blankets are made from jute and sewn in Australia.
