Did you know that it’s super easy to build a worm farm? And a LOT cheaper if you DIY? Composting with the help of worms means that you’ll be contributing a lot less junk to landfill. It also means that you reap the benefits of nutrient-rich soil that plants love. And since I’ve become a bit of a garden-nut recently, a compost was the next logical step for me.
When I checked out the local hardware stores, my excitement came to a bit of a stump. $90 for a worm farm, without any worms in it? That’s a lot for a home for the little critters. Fortunately for me, the fact that I didn’t want to buy a farm wasn’t the end.
So how did I do it? I purchased:
3 hardy plastic containers (dark only and with lids)
A small tap
1 metre chicken wire
This layer is known as the ‘sump’. This is the section that collects the liquid fertiliser. All you need to do here is add the tap at the base, to allow for liquid collection. Perch the sump on some bricks to lift it off the floor and make collection time easier.
The top two boxes will need LOTS of air holes, so go crazy drilling holes in the sides.
In the base of both the boxes, cut a rectangle. This will allow for drainage. You can then attach a sheet of chicken wire to cover the hole – ie allow for drainage but not to let everything just fall out the bottom. I wrapped some wire through for keeping it secure.
Two of the lids will need a rectangle of similar size (to the newly cut holes in the base of Bins 2&3) cut into it. This allows the boxes to rest on each other, and prevents any gaps around the sides for bugs to get it. It also allows for drainage. The Third lid can remain as it is, for going on the top of the farm.
You’re then free to buy the cute little wormies.
The key to keeping worms alive is:
1. Air – lots of ventilation for worm breathing
2. Moisture – wet them occasionally, but the key is good drainage so they aren’t swimming
3. Shade – don’t let them cool in the sun. A garage is perfect
4. Food – feed them weekly, slightly moistened food.
Feed the worms a vegan only diet, but with no citrus or onions, and not too much coffee.
