Red Worms Farm: Reproduce Californian Worm

Vermiculture or Worm Farming consists of the intensive cultivation of the Californian red worm (Eisenia foetida) in organic residues used as fertilizer for agricultural crops. These organic wastes thrown by the Worm, named Humus, represent the highest state of decomposition of organic matter, it is compost of excellent quality. In addition, the Californian red worm has 70% protein, which means that it is ideal for feeding animals such as pigs or fish. Learn all about red worms farm in this article.

The handling of this Worm is very simple and ideal to have on the farm since all organic waste such as animal manures and leftover vegetables from crops is its food. The differences between the Red Worm and the common earthworm are clear. In the case of the Red Worm, can multiply up to 512 times in the course of an active life. Meanwhile, a wild or common earthworm can multiply only 4 to 6 times during life.

The Californian red worm is an incomplete hermaphrodite: male and female at the same time. Therefore, 2 worms are necessary for reproduction. Then, as a result of two worms, an ootheca or capsule of each one will be produced, which will hatch after 17 to 21 days of placement, giving rise to 2 to 20 juvenile worms.

Red Worms Farm: Reproduction of Red Worm

The worm lives for approximately 16 years, during which it mates regularly every 7 days if the temperature and humidity of the environment are to your liking. The Red Worm reaches sexual maturity at 3 months of age. As a result of the coupling of two worms, two eggs or capsules will be produced (one from each earthworm). These capsules will open after 12 to 21 days of incubation, depending on the temperature of the medium where they are located. Each egg or capsule contains 2 to 21 small worms. The number depends on the management that is being given to the Vermiculture (food, the acidity of the environment, humidity, temperature, etc.). constant control of temperature, pH, and aeration are some of the most important factors for success.

The environmental conditions must be optimal, either for the production of humus or for sexual activity. A good temperature of the immediate environment oscillates around 66-68 ºF (19-20 ºC). Temperate climates, such as the coffee zone, are ideal for the cultivation of the worm. Likewise, the handling that is given to the Vermiculture is very important as it is an ideal food, quality water, and in the necessary quantity.

Two red worms can produce, each one, under normal conditions, about 1,500 worms a year, therefore a couple will give rise to 3,000 worms. Every 14 days the capsules break, giving rise to 20 newborn worms that at three months will already be sexually mature and these, in turn, will multiply among themselves.

From the moment of their birth, the worms are self-sufficient; They eat alone and they only need to survive that the substrate where they are found in moist and tender enough.

Scientifically it is proven that there are no differences in performance with respect to the infrastructure chosen to grow worms or to obtain humus. No difference was found in the worm population in beds or boxes and pit environments.

Beds or Boxes for Red Worms

They constitute the space in the space in which the Vermiculture process is carried out. You can use mat, bamboo or brick manufacture. These must be built 1 m wide and the length according to the availability of the land; in general modules of 2 to 3 meters long are used. The most usual bed height is 16” (40 cm). The space between beds can be 20”x20” (50×50 cm). Some vermiculture uses wooden boxes or plastic baskets.

Inside the beds, a cement floor, plastic cloth, mat, or some material that allows the crop to be isolated from the soil is recommended to avoid attack by possible pests (flat-worms as planarians, leeches, ants). The floor built with a slope between 2 and 5% prevents flooding of the bed when irrigation is used.


It is recommended to isolate the crop from direct rain, provides shade, and better conditions for the worm to work. In addition, it facilitates the handling of materials. The height can be about 98”x 120” (2.50 to 3 m).


It is convenient to close the house with fabric for shade or mesh to avoid the entry of birds and other predators.

Sowing system

Vermiculture begins by depositing the broodstock on the beds, making sure that this initial layer is approximately 4”x6” (10 to 15 cm). If necessary, you can complete this height by depositing the substrate at the bottom of the bed and then placed on top of the brood food. This ensures that the red worm has the means to take refuge if food conditions are not adequate.

Red Worms Farm: Worm Farming Management

A. Food: Use thin layers of food (maximum 4 cm), to avoid heating it when it is used very fresh, to facilitate the aeration of the crop, ensure the transformation of the material, and keep the worms feeding on the upper part. A piece of advice: something to stimulate reproduction, a simple change of diet with other residues turn the process in a successful one. Such as manure from different animal species (cattle, pigs, horses, rabbits) or residues from other crops. In our experience, pig manure was the best substrate for the production of worms (compared to horse manure), since it presented the most favorable conditions, obtaining a larger size.

B. Frequency and quantity: It can be fed once or twice per week, depending on the density of the worms and the type of food. The amount of food is directly related to the number of red worms. Calculate a consumption equivalent to half the weight of worms per day. It is advisable to keep records of the diet and the general functioning of the Vermiculture. Remember to move the soil to aerate every 2 or 3 days, after placing food and after watering.

C. Irrigation: Prepare the food before taking it to the worm beds. Soak in it’s necessary, until being totally moistened, it does not drain. This roughly corresponds to a range of 50 to 85% humidity. Soak the beds to retain this moisture. Prepare irrigation with clean water and depending on the environmental conditions and the thickness of the layer of substrate with worms.
