Worms are kept in beds. The width of the bed (respectively, of the flower-bed) is up to 1 m., and its length is 2 m.
Several beds adjacent to each other form a flower-bed. The length of the flower-bed depends on the number of beds and it’s usually 10 meters.
Before placing the beds in the flower-bed, organic fertilizer must be placed, which will be processed in layers of 50 mm thickness. The worms are placed above that layer of organic matter (manure) and above them - another layer of organic matter (up to 150 mm thick). With that - the bed is formed and after that you put 23-30 kg. of organic fertilizer on the bed every 15 days, because every new layer of organic fertilizer is processed by the worms for 15 days.
3 months after you put the Californian Worms on the bed, the number of worms has doubled. It takes 3 months for the worms to create a new generation.
