Why Do People Plant Marigolds Around Tomato Plants?

Marigolds have been a popular flower for many years and are often seen in gardens and flower beds. But did you know that planting marigolds around tomato plants can have significant benefits for the health and growth of the tomatoes?

1. Natural pest control

One of the major benefits of planting marigolds around tomato plants is that they serve as a natural pest control. Marigolds contain a chemical compound called thiophenes, which repels certain pests such as nematodes, aphids, and other harmful insects. This means that by planting marigolds around tomato plants, they act as a natural barrier and protect the tomatoes from infestations.

2. Companion planting

Companion planting is a popular practice where certain plants are grown together to benefit each other. In the case of marigolds and tomatoes, the combination works well because marigolds release a chemical called alpha-terthienyl, which helps to keep harmful nematodes at bay. By planting marigolds around tomato plants, the nematodes are deterred from attacking the roots of the tomatoes, which can cause diseases and stunt their growth. In addition, marigolds attract beneficial insects such as ladybugs and hoverflies, which prey on harmful insects and pests.

3. Improved soil health

Marigolds have an effective way of improving the soil health in a garden. They are known to produce a chemical called alpha-terthienyl which helps to suppress soil-borne pathogens that can cause diseases in crops. By planting marigolds around tomato plants, the soil is enriched with this chemical compound, which protects the roots of the tomatoes and promotes healthier growth.

4. Beautiful aesthetics

Aside from the health benefits, planting marigolds around tomato plants also adds a touch of beauty to the garden. The bright, cheerful colors of the marigolds make a stunning contrast with the deep green leaves of the tomato plants. Not only do marigolds provide beauty and color, but they also add texture and variety to the garden design.

In conclusion, planting marigolds around tomato plants has numerous benefits for both the health of the tomatoes and the beauty of the garden. They provide natural pest control, encourage companion planting, improve soil health, and are aesthetically pleasing. So, next time you are planting tomatoes in your garden, consider adding some marigolds to the mix, and you will reap the rewards of this winning combination!
