We’ve wanted a proper worm farm for ages but it wasn’t until we spotted an old bath pretending to be a water trough at Nic and Lou’s place that I put in the effort to make one. I had some left over 40mm thick pine from the stables fit out and scrounged a few left over plumbing fittings from the shed so we only had to spend a few dollars on the Tiger worms.
Wooden slats provide the base for the drainage system, otherwise the worms will drown if too much liquid builds up. You want the liquid to drain out but not the dirt.
Some chicken wire squashed in the bottom provides support for the last layer – shade cloth.
The wooden edge extends over the lip of the bath to stop the worms escaping. Otherwise, on dark, wet nights they can mass-migrate.
Using the bath drain we can let the liquids out – worm tea (as it’s euphemistically named) makes great fertiliser!
Here are the wee guys in their new home – a bath full of rotted horse manure. The next step is to build a lid to shade them from the sun and heavy rain.
