I Have a worm box, its just a large plastic container which you can pick up from Adsa , etc., about two feet square with a close fitting lid. It has shedloads of brandlings and gilt tails , they are randy buggers and breed like rabbits.
Drill a number of small holes in the bottom, then just a few around the sides.The worms need some air circulating.
Line the bottom with a couple of sheets of newspaper, right up to the walls, then give it a layer of about 4 inches, of good quality peat, garden soil is no good , it will just go hard . You do need however something like some clean fine sand , not much, just a scattering , because worms have no teeth and digest their food by grinding it up in their stomachs against bits of grit. Crushed eggshells work well as well.
Tear a newspaper into strips about an inch wide, then scatter it all over the surfaace of the peat , and cover with another 4 inches of peat, now sprinkle about a pint or so of water onto the peat ,not too much, it needs to feel like a sponge if you squish it in your hand, if it drips lots of water out then there is too much , now throw in your breeding stock.
You should be able to buy a big container of worms from your local tackle shop.
Finally throw a lot of vegetable peelings, banana skins, cabbage, apples, carrots, turnips peelings , just about any veggie bits ,tea bags are good as well, on top of the peat, put the lid on it and leave it.Top up the veggie peelings about every 3 or 4 weeks, they rot down and turn into food compost which the worms love
The worms reproduce and can double the numbers in about 2 months .
Dont try to keep Lobworms , they will just die, they need a different type of habitat.
Another thing to look out for is to make sure the lid fits quite well. I had a bit if a disaster a couple of months ago, a shrew got inside the box, and ate about 90 % of the worms, I found it dead on the surface it had literrally ate itself to death .
Good luck, you could call it Diddly Squat Farm .
