WORM PILES
The worms have only really been thriving for the past 2 months. From what research I've done, most people think harvesting should be done around the 4-6 month mark.

In relocating the worms, we tried to save as many worm capsules as possible. But worm capsules are tiny semi-transparent yellow things which proved very hard to find. So I'm not sure if the worms aren't producing a lot of capsules yet, or we just couldn't find them to begin with.
Generally the worms in the worm farm are smaller than the ones found in our backyard. I wonder if that's because the local worms have acclimatised to the type of soil in our area.. or maybe they're just different species of worms. The worms I'm farming are Red Wigglers, Indian Blues, Tigers and Gardener's Friends. The last species supposedly grow to quite a length and is the best for soil aeration - hence the name.
