Line the bottom layer of your container with two sheets of newspaper, then fill the container half way with compost, grass clippings and moist shredded newspaper (see Fig 2).
Add the compost worms (Tiger or Red worms). Don’t add too many as they will breed and grow in direct proportion to the feed provided and the size of the worm farm.
Water till moist then cover the container with a garbage bag, plastic sheet a hessian bag.
Starting with a small amount of food in the first week gradually increase this amount over the next 6 months. It is best to feed your worms weekly.
After feeding the worms, cover the organic scraps with some compost or soil to avoid attracting vinegar flies.
Add water every few days or when necessary (especially during hot spells) to prevent the worm farm from drying out. It is important to keep the worm farm moist, as the worms may die if it dries out. However, the worm farm should not be soggy either. Remember, there is moisture in the organic scraps.
If the worms outgrow your container, simply remove the container lid and add another level on top of the original. Insert several holes (2cm wide) into the bottom of the container.
With the new level, place food with compost to attract the worms to enter the new container therefore increasing your casting volumes. You can harvest your castings after a few months when the worms have relocated to the above level where the food is. Make sure to replace with new compost and start again by adding levels.
