Did You Know?
1. Earthworms are not only good for gardens but also have a positive impact on forests, fields, and even wetlands. They aerate the soil by burrowing through it, allowing oxygen and water to reach plant roots more easily.
2. While earthworms are commonly known for their beneficial role in soil health, they have been on Earth for over 120 million years, making them one of the oldest known species to have survived to this day.
3. In their lifetime, earthworms can ingest up to half of their body weight in organic matter every day. They digest this organic matter and release nutrient-rich castings, also known as worm manure, which greatly improve the fertility and structure of the soil.
4. Earthworms possess the ability to regenerate if they lose a segment of their body. Through a process called autotomy, they can shed a damaged or severed part and grow a new one, adding to their remarkable adaptability.
5. Charles Darwin, the renowned naturalist and father of the theory of evolution, was fascinated by earthworms and extensively studied their behavior, diet, and impact on soil. In fact, he wrote an entire book titled “The Formation of Vegetable Mould through the Action of Worms” that delved into the intricacies of earthworm ecology.
Benefits Of Earthworms In Gardens
Earthworms enhance soil quality and improve the overall health of gardens. They have several advantages for plants:
-
Earthworms enhance the soil structure by creating aggregates through their castings. These castings combine minerals and organic matter, forming a crumbly and nutrient-rich soil texture. This improved soil structure enhances water infiltration, allowing for better drainage and reducing the risk of waterlogging in gardens.
-
In addition to improving water infiltration, earthworms also contribute to soil aeration. Their burrowing activities create passageways that facilitate oxygen exchange between the soil and the roots of plants. This increased oxygen availability promotes the growth of beneficial soil organisms and prevents plant roots from suffocating.
-
Earthworms play a vital role in nutrient cycling and availability. They consume organic matter such as decaying leaves and plant debris, breaking it down into smaller particles. During this process, the organic matter is partially digested and deposited as castings, which are rich in nutrients like nitrogen, phosphorus, and potassium. These nutrients are then made readily available to plants, contributing to their growth and vitality.
It is worth noting that while earthworms offer numerous benefits to gardens, they are not necessarily a prerequisite for healthy soil. If the soil is of good quality, earthworms will naturally establish themselves over time. Therefore, it may not be necessary to purchase worms to introduce into the garden, as they are likely to show up on their own.

Harmful Effects Of Earthworms In Natural Ecosystems
Although earthworms can be beneficial in gardens, their presence in natural ecosystems can actually have detrimental effects. Specifically, in the northeast United States, all earthworm species are introduced from Europe and Asia, as the impact of glaciers during the Ice Age eliminated native species. This introduction of non-native earthworms has had severe implications for the delicate balance of natural ecosystems.
In forest ecosystems, the absence of earthworms used to be a defining characteristic, with undisturbed forests featuring deep layers of organic litter on the forest floor. However, the arrival of earthworms has resulted in the rapid consumption and decomposition of this deep litter layer. This disruption in nutrient and carbon cycles can have far-reaching consequences, as it can favor invasive plants that thrive in disturbed soil, while adversely affecting native plant species.
Among the invasive earthworm species, Asian jumping worms pose a particular threat. These worms exhibit an aggressive feeding behavior and can rapidly consume large quantities of organic matter. Their presence can lead to the loss of understory plants, reduced leaf litter, and a modification of soil structure.
It is crucial to exercise caution and prevent the movement of earthworms from one location to another, particularly when dealing with invasive species. Introducing or relocating earthworm populations can have negative consequences for natural ecosystems and disrupt the delicate balance that supports various flora and fauna.

Earthworms In The Northeast United States: Introduced Species
The northeast United States does not have any native earthworm species due to their elimination during the last Ice Age. All 16 reported species of earthworms in New Hampshire and surrounding areas have been unintentionally introduced from Europe and Asia.
While earthworm activity can benefit gardens, it is crucial to recognize that these introduced earthworm species have the potential to disrupt natural ecosystems and alter soil conditions. The northeast region’s distinctive forest ecosystems developed and functioned for thousands of years without the presence of earthworms. Their introduction can drastically change the dynamics of these habitats.
Therefore, it is advisable to preserve the integrity of New Hampshire’s woodlands by refraining from introducing more earthworms to the landscape. By allowing earthworms to naturally show up in good garden soil, we can benefit from their positive contributions without causing harm to these precious natural ecosystems.
Redworms And Vermicomposting: Potential Ecological Threats
Redworms, specifically red wigglers and compost worms, can be easily obtained online for vermicomposting setups. Vermicomposting is the process of using containers filled with organic bedding and kitchen scraps, where redworms are introduced to break down the material and create nutrient-rich compost. Although vermicomposting is a beneficial way to recycle organic waste and produce compost, it is essential to be mindful of potential ecological threats.
In regions like New Hampshire, redworms are unlikely to survive the winter. Consequently, introducing them to outdoor compost piles in this area can lead to the establishment of non-native populations that might outcompete and displace native earthworms. This disruption can have damaging effects on garden soil and natural ecosystems.
To maintain the ecological balance and protect native species, it is advisable to refrain from introducing redworms and other non-native species into outdoor composting systems in regions where they are not naturally found.
- To practice vermicomposting responsibly, consider the following:
- Research the native earthworm species in your region and ensure you are not introducing non-native worms that could disrupt the ecosystem.
- Utilize local resources, such as composting workshops or community garden programs, to learn about the best practices for vermicomposting in your area.
- If you are unsure about the suitability of redworms for your location, consult with local agricultural or environmental authorities for guidance.
“The introduction of non-native redworms into outdoor composting systems can lead to harmful consequences for native earthworm populations and ecosystems.”
Attracting And Maintaining Earthworms In Gardens
If you wish to attract and maintain earthworm populations in your garden, there are several practices you can adopt. Adding organic matter, such as compost or composted manure, provides an excellent food source for earthworms and improves soil moisture-holding capacity. This organic matter not only serves as a nutrient-rich meal for worms but also helps retain moisture, promoting a healthy environment for their survival.
Additionally, incorporating organic matter into the soil through practices such as mulching and cover cropping can attract earthworms. These materials break down gradually, providing a continuous supply of food to sustain earthworm populations.
By creating a favorable environment with good soil structure, organic matter, and adequate moisture, you can encourage earthworms to take up residence in your garden naturally. This approach not only saves money but also helps protect the delicate balance of natural ecosystems in New Hampshire by avoiding the introduction of non-native earthworms.
