Are you interested in organic gardening practices? Do you want to reduce household waste and return essential nutrients to the soil? If so, vermicomposting might be the perfect solution for you. Vermicomposting is a process that uses worms to break down organic material, such as food scraps and yard waste, into a nutrient-rich soil amendment. In this article, we will discuss the different types of worms used in vermicomposting. Regardless of your level of knowledge on this subject, we assure you that this article is the right place to learn and improve your vermicomposting skills.
What is Vermicomposting?
Vermicomposting is a composting method that uses different species of worms to break down organic material into a highly beneficial compound commonly called “vermicompost” or “worm castings”. Unlike traditional composting, which relies on bacteria and fungi, vermiculture (the official name for vermicomposting) adds worms to the equation. These worms consume the organic material and eventually excrete it in a form that is a highly beneficial soil amendment for gardens. Worm castings contain a plethora of microorganisms and nutrients that can help improve soil quality and plant growth.
The Worms that make Vermicomposting possible
Several types of worms are suitable for vermicomposting, but the two most commonly used species are Eisenia fetida and Eisenia andrei. These two types of worms, also known as “red wigglers,” are excellent for breaking down organic material and are easy to maintain in a small space. They have a ravenous appetite, can eat up to half their body weight every day, and are prolific reproducers. Other types of worms, such as Lumbricus terrestris or nightcrawlers, are less suitable for vermicomposting and are commonly used for soil aeration.
Red Wigglers: The Most Common Worms Used in Vermicomposting
Red wigglers (Eisenia fetida) are the most commonly used worms in vermicomposting. They are also known as red worms, tiger worms, or manure worms. These worms are very efficient at composting kitchen scraps and other organic waste.
Red wigglers are different from earthworms that you may find in your garden. They are much smaller, thinner, and have a reddish-purple color. They can eat up to half of their body weight in organic waste per day. Red wigglers can live for up to two years, but in ideal conditions, they can reproduce and multiply quickly.
Red wigglers thrive in temperatures between 55°F to 75°F (13°C to 24°C) and prefer a moist bedding material to live in. If you're starting a vermicomposting bin, make sure to provide them with a suitable environment, such as shredded newspaper, cardboard, or coconut coir, and keep the bedding moist but not too wet.
Red wigglers can tolerate a wide range of pH levels, but a slightly acidic environment (around pH 6.5) is ideal for them. They also need oxygen to breathe, so it's important to keep the compost aerated by tumbling the bin, adding more bedding, or drilling small holes in the container.
When feeding your red wigglers, avoid giving them meat, dairy products, or oily foods as these can cause odor problems and attract pests. Instead, stick to fruits, vegetables, coffee grounds, tea bags, and eggshells. You can chop them into small pieces to help the worms digest them more easily.
Red wigglers are not only great at producing nutrient-rich compost for your plants, but they also help reduce the amount of organic waste that ends up in landfills. With a little bit of care and attention, your red wigglers can happily convert your kitchen scraps into valuable fertilizer.
European Nightcrawlers: A Larger Alternative to Red Wigglers
If you are looking for a larger worm option to use in your vermicomposting system, the European Nightcrawlers are a great choice. These worms are also known as Eisenia hortensis, and they are larger and more robust than the Red Wigglers, making them a better option for outdoor composting systems.
One of the biggest benefits of European Nightcrawlers is their resilience to harsh temperatures. They are able to survive in temperatures ranging from 32°F to 95°F, making them a great option for outdoor composting during the colder and hotter months of the year. They are also more tolerant of moisture levels and can survive in a wider range of bedding materials.
In terms of feeding, European Nightcrawlers are known to eat a wider variety of food than Red Wigglers. They are not picky eaters and will consume a mix of fresh fruit and vegetable scraps, yard waste, and even small amounts of meat and dairy.
However, it is important to note that European Nightcrawler populations grow more slowly than Red Wigglers, so it's best to start with a larger number of worms to establish a healthy population. They also do well in compact, multi-layered composting systems and can handle a depth of around 12 inches.
Overall, European Nightcrawlers are a great option for outdoor vermicomposting systems due to their resilience and ability to consume a broad range of materials. They are a larger and more robust option for those who want to take their composting to the next level.
African Nightcrawlers: Ideal for Tropical Climates
African Nightcrawlers, or Eudrilus Eugeniae, are a popular worm species used in vermicomposting. They are native to tropical regions and are well-suited for warm and humid conditions making them the perfect choice for composting in tropical areas. Here are some of the reasons why African nightcrawlers are the ideal worms for vermicomposting in tropical climates.
- Thrive in Warm Temperatures: African Nightcrawlers love warm temperatures and can easily tolerate a temperature range of 25°C to 30°C while some other worm species like Red Wigglers thrive best in temperatures ranging from 18°C to 25°C. Tropical regions have a warm climate year-round, making African Nightcrawlers a great option for vermicomposting.
- Fast Reproduction: African Nightcrawlers have a high reproduction rate. They breed quickly and produce more offspring. This means that your vermicomposting system will quickly grow in size and produce more nutrient-rich compost. Their fast reproduction rates also ensure that your worm population will not dwindle easily.
- Large Worms with Strong Digestive Systems: African Nightcrawlers are larger in size than other worm species, and can grow up to 6-8 inches long. Their larger size and strong digestive system allows them to process large amounts of waste materials, making them ideal for composting programs that produce a lot of organic waste.
- High Nutrient Production: African Nightcrawlers are known to produce nutrient-rich castings that are high in nitrogen, potassium, and other essential nutrients needed for plant growth. Their castings suppress plant diseases and pests, improve soil structure, and increase water retention in the soil, making them an essential element for any farmer or gardener.
- Low Maintenance: African Nightcrawlers require minimal maintenance compared to other worm species. They are highly adaptable and can survive in adverse conditions such as low moisture and low oxygen. This makes them ideal worms for beginner vermicomposters who do not have experience in managing worms.
African Nightcrawlers are an excellent option for vermicomposting in tropical climates. They are adaptable, fast-growing, produce high-quality castings, and require minimal maintenance. When starting a vermicomposting project in a tropical region, consider using African Nightcrawlers and gradually introduce other worm species as your experience level increases.
Blue Worms: A Lesser-Known Worm with Unique Benefits
