To help keep our house green, we decided to make a worm bin. Worm bins are an easy way of dealing with food waste and generally require less maintenance than a compost bin.
I looked around online for a design I liked. Generally it’s best to have one bin with holes in the bottom nestled within one without holes. That way, the liquid (or worm tea) can drip out of the first bin and be collected in the second. This design includes a third bin, also with holes in the bottom, that one can add once the main bin starts to get full. If you add it on top of the main bin and begin adding food, the worms will move up from the old bin to the new bin (through the holes in the bottom), ultimately leaving you with a beautiful bin of worm castings without having to sort through and remove the worms yourself.
