What do I need to know before I start vermicomposting?
I’ve played with lots of ways to do this, and I’m happiest with what I currently do. First, the outdoor part: 1. Get hold of four old car tyres (low profile fats, preferably – mine are 245/45R17’s). Tyre service centres have big stacks of dead tyres out the back and will be only too happy to see you take some away (they cost the business about $3 each to recycle). 2. Dig two round, flat holes a little less than one tyre deep and a little wider than one tyre wide, sit a tyre in each, and backfill around the outside. You should end up with about 20mm of tread visible above ground level. 3. Sit a second tyre on top of each sunken one. 4. Make round plywood lids (I used hoarding ply scrounged from a building-site dumpster) to fit the rim indentation of the top tyres. Paint the lids white. Sit them in the tops of the tyres and hold them down with a brick each. 5. If your stacks are placed where they’ll get afternoon sun, paint the top tyres white as well. 6. Get about 500g of composting wor
