Worm Farming

Composting worms are different from earth worms, so you need to obtain your initial batch from someone with a worm farm. It’s to do with temperature – it’s too hot in the worm farm for earth worms.

METHOD

  1. Assemble worm farm with the tray with a tap placed at the bottom
  2. In the top tray spread worms, add kitchen scraps and cover with the fibre mat (worm blanket).
  3. Sprinkle with water from time to time to keep moist. Sprinkle with lime to improve ph.
  4. Keep adding scraps cut small – the smaller the pieces, the quicker the worms get through them.
  5. Worms will also eat paper, cardboard, cotton t-shirts – nearly everything!
  6. No onion skins or citrus (too acidic) but possibly these are ok if soaked first (?)
  7. When the top tray is full, rearrange so an empty tray is on top for the scraps & transfer the fibre mat to that one.
  8. Use the contents of lower trays in garden when the food scraps are all broken down and the composting worms have moved out.

  • Keep the worm farm in the shade in summer, but they need warmth, so in winter put it in sun.
  • Keep the tap turned on so farm doesn’t fill with rainwater and drown the worms.
  • Place a bucket under the tap to collect liquid. As it fills, use it to fertilize the garden or potplants.
  • Use a drip tray to prevent brown ‘worm juice’ stains on concrete.

  1. Yep, good to hear your experience, THANKS!
    I hadn’t thought of that – taking care to not throw out the worms since their special job is in the worm farm. (Earthworms take over in the garden.)
    At first I thought I’d do it one tray at a time, then decided to stick all the trays on from the beginning (for somewhere to keep them) and it hasn’t been a problem. Then I rotated them when sawfly maggots moved in and I was advised there was too much acid fruit. I heaped on the lime, then thought I’d give that layer a break and start a new one. This worked well – no more maggots. It’s amazing the worms can climb even when the scrap heap doesn’t touch the top. Maybe my worm-casts won’t be ready for garden use for a long time but my main goal is scrap-disposal.
    Hopefully all this proves the system is quite forgiving – it sure seems easy and I’m impressed that it isnt smelly!

  2. Great info! I used worm farms (3 of them actually, to cope with a family of 6) but eventually gave up due to a few set-backs. However I still have my plastic worm farms and hope to start using them again some day.

    I’d just like to suggest that when first starting a worm farm it’s probably easier to put only one tray on top of the base with the tap. Then when that’s full, add a second tray, and when that’s full finally add the third/top tray.

    By the time the third/top tray is full the first/bottom one will be just right for using on the garden (all the worms will have left it and most will be in the top tray, although a few will still hang around in the middle tray) so that’s when you empty the first/bottom tray. Then it becomes the new top tray and what was the middle tray moves down to become the new bottom tray and the rotation continues over time.

    If you empty the trays too soon you risk throwing out some of your worms so always wait until the top tray is full before emptying only the bottom tray onto the garden.

    Have fun with the little critters! 😀
