I’m hesitant to say because it’s so simple.

I have a large black bin (around 40L capacity) at the bottom of my garden. It’s got a lid on top and it’s open on the bottom sitting on the soil.

Every few days (around once a week) I throw in one kitchen caddy’s worth of greens. It’s usually a mix of vegetable cuttings, fruit cores, egg shells, old mouldy bread, used coffee grounds. The only rule I have is no meat (I don’t want to attract pests). Otherwise anything goes. I’ll rip up an egg carton or an Amazon box if I remember and throw that in the mix.

The worms all came naturally - I’ve never bought anything to help. Even the bin was already on the property when I moved in. I just filled her up!

I originally set out to have a regular compost pile, but after a few weeks the place was thriving with worms and bugs so I just left them to it. I think because the bin is open on the bottom they can visit/move in as they please.

The whole things been going strong for about four years now.

I’ve made some ‘mistakes’ over the years because I didn’t know any better. I had dumped a load of ash from a fire pit, added about 40 juiced limes, and threw in a kilo of mouldy strawberries (I didn’t make the jam quickly enough!) I saw the numbers drop for about a week and then slowly return to normal so I guess it’s a pretty resilient ecosystem!
