BLOG Natural Pest Deterrents: Using Companion Plants to Protect Your Lawn Aug 26, 2026

Maintaining a lush, beautiful lawn is a priority for many homeowners, yet it often comes with the challenge of curbing pests that can destroy all your hard work. At Healthy Roots Landscaping, we believe in sustainable lawn care practices that protect the environment. Among various natural strategies, using companion plants for pest control is both effective and beneficial for your lawn's health.

Companion planting is a gardening technique where specific plants are grown together to mutually benefit one another. It’s a method frequently used in organic gardening that can be equally applied to lawn care. These companion plants help deter pests, improve growth, and enhance the soil quality around them.

One of the most effective companion plants against pests is marigold. Known for its vibrant colors, marigold naturally deters nematodes, aphids, and even some beetles. Planting marigolds around your lawn's perimeter can create a protective barrier. Their roots exude a natural chemical called thiophene, which is toxic to many harmful soil nematodes.

Another excellent choice is lavender. Not only does lavender add a delightful fragrance, but its strong scent also repels moths, fleas, flies, and mosquitoes. The presence of lavender can reduce the need for harsh chemical sprays. Additionally, its attractive purple flowers can enhance the aesthetic appeal of your lawn, drawing in beneficial pollinators like bees and butterflies.

Basil is more than just a culinary herb; it’s a robust pest deterrent against flies and mosquitoes. Companion planting basil in your lawn's border can create an aromatic defense that is both pleasing to the senses and highly functional. Moreover, basil complements plants like tomatoes and peppers, so it can be a fantastic addition if you have a vegetable garden attached to your lawn.

Chrysanthemums are another powerhouse in pest control, containing a natural insecticide called pyrethrin. Pyrethrin is effective against ants, beetles, and even ticks, making chrysanthemums a superb companion plant. Placing these striking blooms around your lawn offers a natural shield against unwanted invaders while lending a visual appeal.

Garlic, commonly used in the kitchen, can also serve a significant role outdoors. Regarded for its pungent odor, garlic is effective against snails, aphids, and Japanese beetles. Planting garlic near high-risk areas of your lawn can help break pest infestation cycles. Furthermore, garlic’s pest-repelling properties work best when planted in dense clusters.

Incorporating these companion plants into your lawn care approach offers several benefits beyond pest deterrence. Naturally addressing pest issues can lead to fewer chemical inputs, which means a healthier, more resilient lawn environment. Beyond that, the diversity of plants can enhance the beauty of your outdoor space, creating an inviting habitat for beneficial insects and wildlife.

Concluding, using companion plants in your lawn strategy can significantly reduce pest problems without resorting to chemicals. At Healthy Roots Landscaping, we recommend experimenting with these companion plants to discover the best combinations for your specific ecological needs. Embracing natural pest deterrents not only ensures a verdant lawn but also supports biodiversity, leading to a more sustainable, environmentally friendly garden.
