What are Cutworms and Why Do They Matter?
Cutworms might look cute, but they’re actually a major threat to young seedlings. Let’s take a closer look at what makes them so problematic for gardeners like you.
The Life Cycle of Cutworms
Cutworms go through a complete metamorphosis, with four distinct stages of development: egg, larva, pupa, and adult. Female moths lay their eggs on leaves or stems of host plants, typically in the fall. The eggs hatch into larvae within 3-4 days, and these cutworms feed on plant foliage throughout the spring and summer months.
Cutworm larvae are voracious eaters, consuming entire seedlings in a single night if left unchecked. They’re most active at dawn and dusk, making it difficult to spot them by day. These hungry pests have no preference for what they devour; they’ll chomp through leaves, stems, and even fruiting vegetables.
As cutworms mature, they begin to look for a safe place to pupate. They spin silk cocoons around themselves and enter a state of dormancy, emerging as adult moths in late summer or early fall. The cycle then repeats itself, with female adults laying eggs on new host plants to continue the next generation.
The Damage Cutworms Cause to Seedlings
Cutworms are notorious for their ability to wreak havoc on young seedlings. The damage they cause can be extensive and devastating if left unchecked. One of the primary ways cutworms harm seedlings is by chewing holes in leaves and stems. These tiny insects use their razor-sharp mouthparts to gnaw through tender shoots, leaving behind ragged edges and torn tissue.
The extent of the damage can vary depending on the type of cutworm, with some species causing more extensive damage than others. For example, the Black Cutworm (Agrotis ipsilon) is known to cause particularly severe damage, often stripping seedlings bare of their leaves in a matter of days. As a result, it’s essential for gardeners and growers to be aware of the types of cutworms that are prevalent in their area.
The destruction caused by cutworms can also have long-term consequences for plant health. In addition to reducing photosynthesis and stunting growth, damaged leaves and stems provide entry points for disease and pests, making the seedling even more vulnerable.
What are Cutworm Collars?
Cutworm collars are a simple, effective tool for protecting your seedlings from cutworm damage, and understanding what they’re made of is key to using them correctly. Let’s dive into how these collars work.
Definition and Purpose of Cutworm Collars
Cutworm collars are an effective and non-toxic method for protecting seedlings from cutworms. Essentially, a cutworm collar is a ring or cuff made of a durable material, such as paper, plastic, or cardboard, that fits around the stem of a young plant to prevent cutworms from reaching it.
The primary purpose of a cutworm collar is to create a physical barrier between the seedling and the cutworm. Cutworms are nocturnal insects that feed on plant stems at night, causing significant damage if left unchecked. By placing a collar around the stem, you make it impossible for cutworms to reach the tender shoots, thus safeguarding your seedlings.
When selecting a material for your cutworm collars, opt for something sturdy yet biodegradable. Some gardeners use toilet paper rolls or newspaper strips as makeshift collars, while others prefer commercial options made from durable plastics. Regardless of the material choice, ensure it’s snugly fitted around the stem to prevent cutworms from slipping underneath.
Types of Materials Used for Cutworm Collars
Cutworm collars are made from a variety of materials, each with its own set of benefits and drawbacks. Paper is one of the most common materials used for cutworm collars. It’s inexpensive, easy to find, and can be easily molded into different shapes. However, paper collars may not provide long-lasting protection and can become brittle over time.
Plastic collars are another popular option. They’re more durable than paper and can provide better protection against cutworms. However, they can also be more expensive and may not biodegrade as quickly as other materials.
Mesh collars offer a unique solution by allowing for airflow while still protecting the seedling from cutworms. They’re often made from breathable materials like nylon or polyester and are designed to fit snugly around the stem of the seedling.
Some gardeners also use copper tape or mesh collars, which are known for their ability to repel insects. These collars work by creating a physical barrier that prevents cutworms from reaching the seedling.
How to Use Cutworm Collars Effectively
To use cutworm collars effectively, you need to know when and how to install them for maximum protection against these pesky pests. We’ll walk you through the process step-by-step.
Installing Cutworm Collars Around Seedlings
To install cutworm collars around seedlings effectively, follow these steps. Start by selecting a collar that is 4-6 inches tall and made from a durable material such as paper, plastic, or fabric. Choose a location where the collar will not be disturbed by watering or weeding.
Begin by gently inserting one end of the collar into the soil next to the seedling, making sure it’s snug against the stem. Then, place the seedling in the collar and secure it with a small rock or stick. Make sure the collar is positioned so that its top edge is at least 2 inches above the soil surface.
As you continue installing collars around other seedlings, keep them spaced about 6-8 inches apart to prevent cutworms from crawling between plants. Finally, inspect your collared seedlings regularly for signs of infestation and adjust the collar’s position as needed to ensure effective protection.
Tips for Ensuring Effective Protection
When using cutworm collars effectively, it’s essential to follow some key best practices to ensure they provide optimal protection for your seedlings. First and foremost, make sure the collars are made of a breathable material that allows moisture to pass through, preventing damage to the plant from excess moisture.
When placing the collars around the seedling stem, gently push them down to the soil level to prevent any air pockets that might allow cutworms to crawl underneath. Also, ensure the collar is not too tight or constricting, as this can cause damage to the stem.
Regularly inspect your seedlings and replace worn-out collars immediately. It’s also crucial to apply collars at the right stage of growth – usually when the seedling reaches about 2-3 inches tall. This ensures that the collar is snug against the soil and effectively protects the stem from cutworm damage. By following these simple tips, you can maximize the effectiveness of your cutworm collars and enjoy a healthier crop.
DIY vs. Store-Bought Cutworm Collars: Which is Best?

Additional Methods for Managing Cutworms
If you’re struggling to keep your cutworm population under control, there are some additional methods worth exploring to protect your seedlings from these pests. These alternative approaches may be just what you need to save your plants.
Companion Planting to Deter Cutworms
Companion planting is an effective and environmentally friendly method for deterring cutworms from seedlings. Certain plants release chemical compounds that repel or attract beneficial insects, which can help control cutworm populations. For example, basil and marigold are known to repel nematodes and other pests that attract cutworms.
Other companion plants like dill, garlic, and mint have natural oils and compounds that repel cutworm moths. Planting these species around your seedlings can create a barrier against cutworm infestations. For instance, basil is often planted near tomatoes to protect them from hornworms and other pests that attract cutworms.
When using companion planting as a method for managing cutworms, remember to plant the companion species in close proximity to your seedlings but not so close that they compete for resources. Also, consider the growing requirements of each plant, such as sunlight and watering needs. This can be achieved by alternating rows or incorporating them into containers with good drainage.
Organic Pesticides for Treating Cutworm Infestations
If you’ve tried other methods and still find yourself dealing with cutworm infestations, it may be time to consider using organic pesticides as a last resort. Before reaching for these products, make sure you understand their benefits and limitations.
Organic pesticides offer a more environmentally friendly alternative to synthetic chemicals, but they can still pose risks if not used correctly. Neem oil is a popular choice for controlling cutworms due to its systemic properties that prevent the pests from reproducing. This oil also has low toxicity levels towards beneficial insects, making it a safer option.
Another effective organic pesticide is spinosad, which targets the nervous system of cutworms and other pests. However, this product should be used with caution as it can still harm non-target organisms if not applied carefully.
When using organic pesticides, always read the label carefully and follow instructions for application rates and timing to minimize risks to your plants and the environment.
Long-Term Prevention Strategies for Cutworms
To effectively protect your seedlings from cutworms long-term, consider implementing strategies such as crop rotation and maintaining a balanced garden ecosystem. These methods can significantly reduce future infestations.
Crop Rotation and Soil Preparation
Crop rotation and soil preparation are two essential long-term prevention strategies for cutworm infestations. By adopting these practices, you can create an environment that’s less conducive to cutworms’ survival and reduce the risk of infestation.
When implementing crop rotation, consider alternating between different types of plants that repel or attract beneficial insects, such as marigolds and nasturtiums, which deter nematodes and other pests. For example, if you’ve grown tomatoes in a particular area, try rotating to a legume like beans or peas the following season. This not only breaks the cutworm’s life cycle but also improves soil fertility.
Proper soil preparation is equally crucial. Test your soil pH levels and adjust them accordingly. Cutworms thrive in nutrient-rich, well-drained soils with optimal moisture levels. To prepare your soil, add organic matter like compost or manure to improve its structure and fertility while discouraging cutworms from inhabiting it. By incorporating these long-term prevention strategies into your farming practice, you’ll create a healthier ecosystem that’s better equipped to withstand cutworm infestations.
Creating a Healthy Ecosystem for Seedlings
Creating a healthy ecosystem for your seedlings is crucial for their overall development and resilience to pests like cutworms. This includes using natural predators to control pest populations, rather than relying solely on chemical pesticides that can harm the environment and contaminate soil.
Introducing beneficial insects such as ladybugs, lacewings, or parasitic wasps into your garden can help keep cutworm populations under control. These natural predators feed on aphids, whiteflies, and other pests, reducing the need for chemical controls. For example, a single ladybug can consume up to 60 aphids per hour, providing a significant reduction in pest pressure.
To create a healthy ecosystem, consider incorporating companion planting into your garden design. Certain plants, such as marigolds, nasturtiums, and basil, repel pests like cutworms due to their strong scents or chemical properties. By pairing these plants with your seedlings, you can reduce the likelihood of cutworm infestations.
Remember, a balanced ecosystem is key to preventing cutworm damage. By introducing natural predators and companion planting into your garden design, you’ll be creating a healthy environment for your seedlings to thrive in.
