These worms(unlike earth worms) would normally live in the top few centimetres of soil or leaf litter as they are primary composters. However we have noticed that the thrive on partially composted matter, and this is what we feed them along with a little fresh stuff for variety!
After several failed attempts at keeping worms we have finally discovered a sucessful method.The bath is a good size to keep the worms housed, and has the added feature of a gentle slope towards a built in drain.The top of the bath is covered with some old windows during the winter to keep out the worst of the weather.
The fluid that drains off the bath is a rich brown colour and is high in plant nutrients. Its advantage over poo, comfrey or nettle tea is that it does not smell. We use it as a feed for plants which are being raised in potting compost which may have exhausted the supply of nutrients in the compost. Further uses of the worms, we have not explored as yet are as feed for the chickens, and using their casts as a potting compost ingredient.There are two more empty baths on site ready to set up.
