I can't wait to start my new worm farm when I'm back in New Zealand, I've had the three boxes sitting & not really known how to start, sure I have a working compost bin, I feed it layer after layer, the worms thrive on used coffee grounds, so looking forward to my worm farm now, thank you Lois NZ

Re: onions as worm food

Hello Lois,

onions can be fed to worms but they are amongst the materials that should be fed in moderation. Worms can handle nearly any organic material as food in their worm farm as long as their bedding stays close to pH neutral and they are not overfed which will show in loads and loads of uneaten food on the surface of their worm bin. It is a good idea to only feed the worms again when most of their food that was previously offered is nearly completely gone.

To learn some more about the different kinds of worm food have a look at our worm food rating list. In it we divided the organic materials into 3 categories

1. Good worm food
2. Moderately good worm food
3 Bad worm food

The link to the worm food rating list is


To prevent problems with the worm bedding in your worm bin it would be good to measure the pH of the bedding frequently (at least once a month) and to regularly add some crushed egg shells, mussel shells or agricultural lime in small amounts to your worm farm. These can act as a buffer to keep the bedding pH neutral and counteract any acidification from certain foods.

Kind regards
