Store bought wormeries are expensive, but they are actually quite easy to make yourself with a little recycling ingenuity.
- Four stacking crates
- Tap (optional)
- Composting worms (available mail order, or from bait shops, or dig them out of an existing compost heap)
Anything stackable can be made into a DIY wormery. The bottom tray needs to have no holes in the bottom, so it collects the worm ‘tea’ that drains out. You can fit a tap if you want too, but you could also just tip the liquid out as and when necessary. The upper trays need to have holes drilled into the bottom so that liquid drains down and the worms can move through the trays.
Depending how snugly your trays fit together, you may need to drill smaller air holes in the sides, so the worms don’t suffocate. A lid prevents too much rainwater from getting in, and the worms from escaping.
