Worm Facts:

  • Worms like dark cool, damp (not wet) dark conditions. 
  • You must get red wriggler, tiger or indian blue worms for your worm farm. These are the most voracious eaters. Worm farm worms are different to earth worms that live in your garden.
  • Worms eat almost anything but don’t overfeed them – that is when the worm farm starts to smell, slime-up and attract flies.
  • The smaller and mushier it is the quicker they eat it.  The love: most food scraps, coffee grinds, tea-bags, ripped-up moist paper and cardboard and egg-shells. They have been known to eat children’s homework.
  • They don’t eat: acidic foods (citrus, pineapple and vinegar), onions, meat and dairy. 
  • Worms have simple needs: that want to eat food scraps, excrete them out as worm castings and reproduce ever 6 weeks.
  • Worm farms do not smell. If you have a smell worm-farm with little flies (vinegar flies) watch the ‘Trouble Shooting’ Worm farm video to find out an easy way to get your worm farm back on track.
  • Worm wee (the liquid stuff collected in the bottom tray of your worm farm) should be diluted with water 10:1  and used on your garden.
  • To make worm-tea take a scoop of castings, mix in a bucket of water and leave for up to 8 hours – no longer as bacteria develops. Pour tea on plants.
