Marigolds, with their bright orange and yellow petals, are not only a visually appealing addition to gardens but also serve as a natural deterrent for various pests. Their strong scent and compounds have been found to repel a range of animals and insects, making them a valuable companion plant for many gardeners. In this article, we will delve into the world of marigolds and explore their pest-repelling properties, focusing on the animals they repel and how they can be effectively used in garden management.
Introduction to Marigolds
Marigolds belong to the family Asteraceae and are native to the Americas. They are annual or perennial plants, depending on the species, and are known for their ease of growth and maintenance. Marigolds are often used as ornamental plants in gardens and landscapes due to their vibrant colors and ability to attract beneficial insects like bees and butterflies. However, their benefits extend beyond aesthetics, as they possess natural compounds that can repel a variety of pests.
Natural Compounds in Marigolds
Marigolds contain several natural compounds, including pyrethrum and limonene, which are known for their pest-repelling properties. Pyrethrum is a natural insecticide that can kill or repel insects, while limonene has been shown to deter certain types of animals and insects. These compounds are released by the plant as a defense mechanism to protect itself from predators and can be highly effective in repelling unwanted pests in gardens.
How Marigolds Repel Animals
The strong scent of marigolds, combined with their natural compounds, can deter a range of animals. When marigolds are planted in close proximity to other plants, they can release their pest-repelling compounds into the soil and air, creating a barrier that repels certain animals. This makes marigolds an excellent companion plant for gardeners looking to naturally protect their crops from pests.
Animals Repelled by Marigolds
Marigolds have been found to repel a variety of animals, including:
- Nematodes: These microscopic worms can cause significant damage to plant roots. Marigolds, specifically the ‘French’ and ‘African’ varieties, have been shown to repel nematodes, reducing the risk of root damage.
- Rabbits: The strong scent of marigolds can deter rabbits from feeding on nearby plants. Planting marigolds around the perimeter of a garden can help protect against rabbit damage.
- Deer: Similar to rabbits, deer are also deterred by the scent of marigolds. Planting marigolds in areas where deer are a problem can help protect plants from deer feeding.
- Whiteflies: These small insects can cause significant damage to plants by sucking sap and transmitting diseases. Marigolds have been found to repel whiteflies, reducing the risk of infestation.
Using Marigolds in Garden Management
To effectively use marigolds as a pest deterrent, it’s essential to understand how to incorporate them into garden management strategies. This includes choosing the right variety of marigold, planting them in the correct location, and combining them with other companion plants to maximize their pest-repelling effects.
Choosing the Right Variety of Marigold
Not all marigold varieties are created equal when it comes to pest repelling. The ‘French’ and ‘African’ marigold varieties are known for their strong scent and high concentration of pest-repelling compounds, making them the most effective choices for gardeners looking to deter pests. When selecting marigold seeds or seedlings, opting for these varieties can ensure the best results.
Conclusion

By understanding the animals that marigolds repel and how to effectively use them in garden management, gardeners can create a balanced and healthy ecosystem that minimizes the use of chemical pesticides. Whether you’re looking to protect your plants from nematodes, rabbits, deer, or whiteflies, marigolds are a simple yet effective solution. With their ease of growth, vibrant colors, and natural pest-repelling compounds, marigolds are an excellent choice for gardeners seeking a holistic approach to pest management.
What types of pests do marigolds repel?
Marigolds are known to repel a variety of pests, including nematodes, whiteflies, and aphids. These pests can cause significant damage to plants, and using marigolds as a natural deterrent can help to minimize this damage. Marigolds contain a chemical called alpha-terthienyl, which has been shown to repel nematodes and other pests. This chemical is released into the soil and air, creating a protective barrier around the plants.
The repelling properties of marigolds can be especially beneficial for gardeners who are looking for a natural and non-toxic way to protect their plants. By planting marigolds alongside other flowers or vegetables, gardeners can create a diverse and balanced ecosystem that is less susceptible to pest infestations. Additionally, marigolds are easy to grow and require minimal maintenance, making them a great addition to any garden. With their bright orange and yellow flowers, marigolds can also add a pop of color and vibrancy to the garden, making them a great choice for gardeners who want to create a beautiful and functional outdoor space.
Do marigolds repel rabbits and other small animals?
Marigolds are known to repel a variety of small animals, including rabbits, deer, and squirrels. These animals tend to avoid plants with strong, pungent scents, and marigolds have a distinctive smell that can help to deter them. By planting marigolds around the perimeter of the garden, gardeners can create a barrier that helps to keep these animals out. This can be especially beneficial for gardeners who live in areas with high populations of small animals.
In addition to repelling small animals, marigolds can also help to deter other types of pests, such as snakes and insects. The bright colors and strong scent of marigolds can make them unappealing to these animals, which can help to keep them away from the garden. By incorporating marigolds into their garden design, gardeners can create a comprehensive pest-deterrent system that helps to protect their plants from a variety of threats. With their natural repelling properties and low-maintenance requirements, marigolds are a great choice for gardeners who want to create a safe and healthy garden ecosystem.
How do marigolds repel nematodes?
Marigolds repel nematodes through the release of chemicals into the soil and air. The alpha-terthienyl in marigolds has been shown to be toxic to nematodes, and can help to reduce their populations in the soil. When marigolds are planted in the garden, they release this chemical into the surrounding soil, creating a protective barrier that helps to keep nematodes away.
