The bannah grass and Acacia leaves make great compost (but we just killed the Acacia, oh well).
Pulling apart the bin is a bit of a progression in that it takes a few goes to get there. If you don't mind cockroaches you can maybe go quicker.
The top layers tend to harbour cockroaches. I let them escape and leave the lid off so that the worms can retreat into the dark. That's when I take a few bucketfuls of the worm goodies and spread them around or put them somewhere out of the sun and rain. Once you expose worms, leave it again for a few hours/days. Then you can collect some more. It gives a few things a chance to move out before you take their home away.
As I rolled the tyres around big clods of worm poo was falling out.. fertilising on the go!! The tyres are going to be moved to a new spot in our front garden to help the hedge grow faster.
This one has lots of roots in it. I'm guessing asparagus, but not sure yet. Have to keep digging.
This is the lower part of the worm bin, it is drier and a bit more aged. Even if the nutrients are gone, this adds humus and structure to the soil when it is added. As you can also see, we eat a bit of chicken. One weird phenomena with these loooong time composts is that as you get closer to the bottom, more and more concentrated layers appear.. eggshells, bits of plastic, some still totally readable and brightly coloured. And allllll the bones.. I did put a dead raven in here at one point.. didn't manage to come across it's skull though in my unruly vermicompost digging.
It adds a fair bit of time to having to sort it out though and these little bits of plastic and bones are fiddly to have to pick out. We have a sieve (plastic plant tray with big holes) to help get some of the bones out.
