Earthworms are one of nature's most entirely beneficial creatures, breaking down and detoxifying underground dead matter as they aerate and fertilize the soil. Worms are increasingly grown by residential growers for kitchen waste consumption, gardening and animal food, as well as for industrial waste and farming uses.

Another bonus is that worms are easy and rewarding to raise. It is a healthful and sustainable back-to-nature trend, especially as agriculturists look to minimize use of commercial fertilizers and better handle organic waste. In this article, we'll take a short review of worm farming and different types of growers, and the most popular methods and products to get you started.

Overview of Worm Farming

The scientific term for composting with worms is vermicomposting, which produces high quality organic vermicast as the final product. These castings are the result of the worm's digestion, and make an excellent, clean and nutritious soil amendment.

Meet the Composting Worm

The most common kind of earthworm used for vermiculture are called "red wigglers," though white worms, night-crawlers and other varieties are also used. Red wigglers are the most commonly recommended because they are voracious eaters and breed prolifically, and are well-suited for efficient composting.

The main advantage of red wigglers is that they remain close to the surface, unlike most local worms you might find on sidewalks after a rain. Earthworms usually like to dig deep, but red wigglers are by nature happiest in manure and sludge, so they may be kept in shallow beds where the food consumption and soil moisture can be closely monitored.

Commercial operations can be carried out for large-scale vermiculture due to the red wigglers' fortunate habits, and residential units have been developed that are simple, compact and clean while allowing the animal a compatible setting. For this reason, red wrigglers are considered the standard composting and bait worm. You can easily buy red wigglers and other worm varieties from online suppliers or local bait shops.

Types of Vermiculture

There are different kinds of worm composting and growers, from home farmers to industrial-scale practitioners. Each type of farming scale has its own optimal methods and products. The worms may be the same, but the scale of their production is a major factor, as the size of a vermiculture operation determines which products and methods are most effective.

In the industrial production sector, vermicomposting is used for both fertilization and reduction of soil contaminants—including treatment of sewage and wastewater, and the composting of major animal waste sites.

Home vermiculture is usually done in bins. These specially made containers come in a variety of shapes and materials, and can be homemade or purchased. Even modest, small-scale vermicomposting is useful for transforming kitchen scraps into top-grade fertilizer in a small space.

Vermiculture Practices

Each type of worm farming uses different techniques. Large operations use furrows that can be efficiently maintained with machinery, using a process compatible to modern farming equipment and practices. Home gardeners usually resort to cleaner, compact container housing for maximum efficiency and convenience in a small area.

Factory Worm Farming

An increasingly common use of worms is to convert wastes into clean organics. The worms live in the organic waste and digest the compounds into beneficial compost. Farming worms for sale to retailers and other commercial outlets is another common application, and in that case the worms are fed and grown for that purpose.

There are two major processes of big-time worm composting: the windrow system, and a flow-through design. Windrows are long furrows which are filled with organic materials which the worms consume. The worms simply stay in the trench with the food, avoiding the expense of retaining walls and other construction.

The flow-through technique uses the worm's natural migration toward food substances to aid cleanliness and reduce the need for physical separation. Organic material is placed at one end of a worm bed, and additional food is continually added forward into new, clean bedding. The worms migrate to the fresh food, leaving their digested, fertile castings behind. Harvesting is then simply a matter of taking up the rich dirt vacated by the worms.

Home & Garden Vermiculture

The flow-through system is used in most smaller-scale units. There are plenty of DIY instructions online for those inclined, though for kitchen or other indoor use a professional product may be preferable. There are attractive commercial bins that look nice in a home setting, and offer the advantage of helping residential growers avoid troublesome temperature extremes of an outdoor setup.

Home users and gardening enthusiasts place a premium on space, and the flow-through method works nicely with compact stacking trays. These systems use a vertical design, with the food placed in the top tray so that the worms are continually enticed to migrate up.

Vermiculture Products

Worm farming is a growing market, no pun intended. Industrial vermiculture has been adapted for use with existing machinery, but several specialized vermiculture containers have been designed for convenient residential growing.

Popular examples of stacking innovation are The Worm Factory models. These units are easy to set up and harvest from, with minimal disturbance to the worms. Based on a flow-through system, food is put into the top level for worms to naturally flow into, leaving their organically enriched and digested waste behind.

Additional trays can be added to expand the system. Be aware that, though these units are molded plastic and self-reinforcing by their geometry, they do become less sturdy under the weight of the full number of trays. Also, some users may need to add a handmade filter to prevent clogging of the spout.


is a similar tray-stacking composter, with 5 levels designed for flow-through tasks and greater ventilation. The unit is attractive and easy to set up and use, though the large ventilation holes may require attention to avoid insect infestation. This unit also has a 3 year warranty.

An attractive and well-insulated unit that can be used inside or out is the Hot Frog Living Composter. Following the flow-through method with removable trays, the Hot Frog has an appealing look that goes well with most home or patio decor. The double-walled lid and base provide insulation, but also traps heat, so it can't be used in direct sunlight—though no composter is truly suitable for full sun.

One popular model that uses a larger, single-bin design is the Hungry Bin Worm Farm. The efficient, funnel-shaped container is basically one large, vertical flow-through bin. The system empties into a large pullout tray at the bottom instead of a spigot. The semi-outdoor composter has good capacity, but it can allow for worm escape if temperatures rise too high.

Another unique design is featured in the Urban Worm Bag, which uses a single-compartment framework in the form of a durable, breathable fabric pouch. The large area and simple construction makes for a great value considering the space it offers. Buyers should note that, though the fabric seems rugged, it's not optimal for outdoor use where rain, sunlight or marauding critters can reach it.


This is just a sample of popular home composters--bulk supplies and complete kits are also available online. Whether using a tractor for a long windrow, or just a small set of trays under the sink, the basics of worm farming are the same. If you decide to become involved, make sure to research the process and decide the kind of vermiculture you're interested in.

You may not think of a worm composter as a kitchen appliance, but a clean commercial unit will not look out of place in a home setting. You won't have to let people know you grow worms ... until they are ready for that information. If you're ready to save the planet and/or start a new hobby, vermiculture is an amazing natural process and a lot of fun, with benefits.
