What is a worm farm?

A worm farm is the home of worms and the place where they turn kitchen waste into valuable humus. It usually consists of 3- 4 levels, preferably boxes that can be easily stacked inside each other. The lowest level should ideally have a small drain, because that is where the liquid, called worm tea, is collected.

Through the small drain cock, you can easily let this worm tea run out. The next box is placed on the lowest box and filled with untreated moist soil and a few kitchen scraps. To loosen the soil, you can use crushed and damp cardboard. When it comes to kitchen waste, make sure that you do not use meat, fish and citrus fruits.

Worms like very much, for example, used coffee filters with the coffee grounds. This is the floor where the worms go in. The next box is placed on the box with worms. In this one you can put fresh kitchen waste after 3-6 months and the worms will move up and start to utilize the new waste. Of course, the two boxes must each have holes in the bottom area so that the worms can migrate up and any liquids can flow to the lowest level.

When this crate is again well filled with worm humus, place the 3rd tier on top of the 2nd tier and fill it again with kitchen waste. The worms crawl into the next crate and so you can harvest the worm humus from the 1st floor wonderfully easy.

Shredded newspaper, egg carton or cardboard are suitable for loosening. This is moistened and added to the kitchen waste.

Excess moisture can drain down through the holes in the bottom of the boxes.

You should also keep an eye on the number of worms, because they multiply relatively easily and quickly. During the winter, the boxes must be housed frost-proof.
