Reasons to Plant Marigolds with Tomato Plants

Are you looking to enhance your tomato garden and improve the health and productivity of your plants? Consider companion planting marigolds with your tomato plants. Marigolds not only add a beautiful pop of color to your garden but also provide several benefits that can help your tomatoes thrive. In this article, we will explore the top reasons why planting marigolds with tomato plants is a great idea.

1. Natural Pest Control

Marigolds have natural pest-repellent properties. Their strong scent helps deter pests like aphids, nematodes, and whiteflies from attacking your tomato plants. By planting marigolds nearby, you create a barrier that can protect your tomatoes from these common garden pests. This natural pest control method reduces the need for harmful chemical pesticides, making it an environmentally friendly choice.

2. Attract Beneficial Insects

In addition to repelling pests, marigolds also attract beneficial insects to your garden. Bees, ladybugs, and hoverflies are just a few examples of beneficial insects that are attracted to marigolds. These insects help with pollination and prey on harmful pests, further protecting your tomato plants. By planting marigolds, you create a welcoming environment for these helpful insects, promoting a balanced ecosystem in your garden.

3. Soil Improvement

Marigolds are known for their ability to improve soil health. They release a natural compound called alpha-terthienyl, which helps suppress nematode populations. Nematodes are microscopic worms that can damage the roots of tomato plants, leading to stunted growth and decreased yield. By planting marigolds, you can naturally reduce nematode populations in the soil, creating a healthier growing environment for your tomatoes.

4. Weed Suppression

Another benefit of planting marigolds with tomato plants is weed suppression. Marigolds have dense foliage that helps shade the soil, preventing weed growth. This means less time spent on weeding and more time enjoying your garden. Additionally, marigolds release chemicals into the soil that inhibit the germination of weed seeds, further reducing weed growth in your tomato patch.

5. Companion Planting Aesthetics

Aside from their practical benefits, marigolds also add aesthetic appeal to your tomato garden. With their vibrant yellow, orange, and red flowers, marigolds create a visually stunning contrast against the green foliage of tomato plants. This combination not only enhances the overall beauty of your garden but also attracts attention and admiration from visitors.


By planting marigolds with tomato plants, you can enjoy a range of benefits, including natural pest control, attracting beneficial insects, soil improvement, weed suppression, and enhanced aesthetics. Make sure to choose the right marigold varieties that are compatible with your tomato plants and provide the ideal growing conditions for both. With this simple companion planting technique, you can create a thriving and beautiful tomato garden.
