How to Use Composting to Control Garden Pests Naturally

Garden pests can be such a pain, destroying your precious plants and leaving you frustrated.

While chemical pest control provides immediate relief, it poses long-term risks to the environment.

Fortunately, there are safer and natural ways to control garden pests, and composting is at the top of the list.

For this reason, I have put together this blog post to help you understand how to use composting to control garden pests naturally.

By doing so, you can protect your garden and the environment.

Let’s dive right in.

Understanding Composting

Composting is a process in which organic matter decomposes and transforms into a nutrient-rich soil amendment. There are two basic types of composting: aerobic and anaerobic. Aerobic composting requires oxygen and takes place more quickly. Anaerobic composting can take much longer and does not require oxygen. As a home and garden enthusiast, I have had experience with both types of composting. The benefits of composting are numerous. First and foremost, it’s an environmentally friendly way to dispose of organic waste. Additionally, composting helps to enrich soil, reduces the need for chemical fertilizers, and increases moisture retention. Furthermore, composting can also help to prevent soil erosion and lower greenhouse gas emissions.

A Brief Description of Garden Pests and Their Effect on Plants

Garden pests cause harm to plants in various ways. Some pests consume the leaves, flowers, and fruits of plants, while others burrow into the soil and chew away at the roots. Common garden pests include aphids, caterpillars, grubs, slugs, and snails.

Aphids are one of the most common pests in vegetable gardens, and can cause significant damage to plants by sucking the sap from the leaves and stems. Caterpillars, grubs, and cutworms are other types of pests that chomp on the foliage of plants, often rendering them unfit for human consumption.

Similarly, slugs and snails might not seem like a significant threat, but they can cause serious damage. They prefer to come out at night and feed on the leaves, tender stems, and even roots of plants. Eventually, the plants wilt and die, or become stunted and less productive.

Negative Impact of Chemical Pest Control on the Environment

Chemical pest control is the most commonly used method of pest control in gardens. However, they pose a massive threat to the environment as they can be toxic to non-target insects, birds, and animals. Chemicals and pesticides can leach into soil and groundwater, contaminate food crops, and harm beneficial bugs like bees and butterflies.

Besides, constant use of chemicals can lead to pests developing a resistance to them, making it even harder to control them. By using composting as a natural method of pest control, you decrease the chances of harming the environment and non-target insects.

How Composting Helps Control Pests

Composting can be used to control pests in a few ways. First, the heat generated during the composting process can kill off many harmful pests. By composting materials that are infested with pests, you can get rid of them before they can do any damage to your garden.

Compost can also be used as a natural pesticide. The nutrients and beneficial microorganisms in compost help to build strong, healthy plants that are better able to resist pests. This is because healthy plants are less attractive to pests than weak, unhealthy ones.

Another way that compost can help control pests is by attracting beneficial insects to your garden. Beneficial insects such as ladybugs and lacewings feed on harmful pests like aphids and caterpillars. These insects are attracted to the diverse range of organic matter found in compost, so adding compost to your garden can help to increase their numbers.

Finally, compost can also be used to make a natural pesticide spray. Simply mix finished compost with water and strain out any solids. This makes a potent, yet natural, pesticide that can be used to control a wide range of pests.

Some of the pests that compost can effectively control include aphids, slugs, snails, and spider mites. These pests can cause significant damage to plants, but by using compost to control them, you can avoid the negative impact of chemical pesticides on the environment.

Steps Involved in Composting

Composting is a simple process, but it is essential to follow the right steps to get good results. Here are the steps you need to follow to make compost in your garden:

First, choose the right location for your compost pit. Your compost pit should be in a spot that is easy to access but also out of sight. Use a stake and string to mark the area where your compost pit will be.

Next, gather organic materials such as grass clippings, leaves, vegetable scraps, and fruit peels. Avoid using meat and dairy products, as these materials can attract unwanted pests.

It is essential to have a mix of materials with different carbon to nitrogen ratios. Too much carbon slows down the composting process, while too much nitrogen can cause odors and attract pests.

To achieve the right balance, aim for a 2:1 ratio of carbon to nitrogen. A carbon-rich ingredient example includes dry leaves and straw. For Nitrogen-rich ingredients, you can use fresh green leaves, and vegetable scraps.

Add water to your compost pile to make it moist. It’s essential to keep the compost moderately wet, but not soggy.

Now that you have your foundation materials, it’s time to start building your compost pile by layering the materials you’ve gathered. Start with a layer of sticks and twigs, then alternate between layers of grass clippings, leaves, food scraps, and garden waste.

To activate the composting process, add activators such as manure or old compost to the top of the layers. It is advisable to have three layers of organic materials, and each layer should not exceed 4 inches.

Continue layering until the pile is between 3 and 5 feet high. I recommend stopping after 5 feet, as it’s hard to turn or mix such a large pile.

Finally, cover your pile with a tarp to keep it moist and warm. Turn and mix the pile every two to three weeks. Apply the same balance of carbon and nitrogen by adding compost and additional organic materials.

When the compost is ready, it should look dark brown, crumbly, and have a pleasant earthy odor. Use it as nutrient-rich organic fertilizer for your garden!

Using Compost to Control Pests

One method of using compost to control pests is by applying it as a mulch around the base of plants. The compost will actually emit a chemical that repels pests like aphids, spider mites, and nematodes. By spreading a layer of compost around your plants, you can create a barrier that helps protect them from pests. Additionally, the compost will help retain moisture, keeping the soil healthy and the plants thriving.

Another method is to make compost tea and use it as a foliar spray. This involves steeping a compost-filled bag in water for a few days, after which the liquid can be used as a spray to help control pests. The compost tea can kill harmful bacteria, fungi, and other pests on the leaves and stems of plants. However, it is important to not overuse the spray, as it can also kill helpful insects.

It’s important to note that while composting can be a great way to control pests, it is not a silver bullet solution. It should be used in combination with other organic pest control methods, such as companion planting or crop rotation.

When applying compost to control pests, it is important to keep a few things in mind. First, you should ensure that you are using mature compost and not fresh compost. Fresh compost can actually attract pests rather than repelling them. Additionally, it’s important to not pile the compost too close to the base of the plant, as this can lead to rot and other issues. Finally, you should avoid using compost made from diseased plants or which has been contaminated with weed seeds, as this can cause more problems than it solves.

By using compost to control pests, you can take a natural and eco-friendly approach to protecting your garden. As with any pest control method, it’s important to be mindful of the potential risks and to follow best practices to ensure that you’re using compost safely and effectively.

The Dos and Don’ts of Composting

Composting is an easy and low-maintenance way to enrich your soil, control pests, and reduce waste. However, like any garden activity, composting has a set of basic rules and common mistakes to avoid. Here are some dos and don’ts to keep in mind:

DO: Use the right materials

Add a mix of browns (carbon-rich materials) and greens (nitrogen-rich materials) to your compost bin. Browns include dried leaves, twigs, and newspaper, while greens include vegetable scraps, grass clippings, and coffee grounds. Aim for a ratio of 3:1 (browns to greens) for optimal compost. Be sure to avoid adding meat, dairy products, and dog or cat feces, which can attract pests and emit harmful odors.

DON’T: Leave the compost bin uncovered

Uncovered compost can lead to moisture loss, which slows down the composting process. It also allows unwanted pests to take up residence in your compost. Cover your bin with a lid or tarp to keep out unwanted pests and maintain the right level of moisture.

DO: Turn your compost regularly

Turning your compost allows air to circulate and speeds up the composting process. Use a pitchfork or compost aerator to turn your compost pile once every two to three weeks. This also helps to break down big clumps of material and improves the composting process overall.

DON’T: Overwater your compost

While it’s important to maintain the right level of moisture in your compost, too much water can make it soggy and prevent air circulation. This slows down the composting process and can lead to unpleasant odor or mold growth. Only add water if the pile feels dry to the touch.

DO: Be patient

Composting is a gradual process. It can take anywhere from several months to a year for your compost to become ready for use. Don’t rush the process by adding excess water or too many new materials at once. By being patient, you’ll have rich, healthy soil in no time.

DON’T: Give up!

Composting can be frustrating at first, especially if you’re new to it. Don’t give up! Keep experimenting with different materials and ratios until you find what works best for you. Remember that composting is an environmentally friendly way to reduce waste, improve your soil, and control pests naturally.
