Companion planting is a technique where different plants are grown together to improve each other's growth and health. One of the most popular companion plants for tomatoes is marigolds. However, not all marigolds are created equal when it comes to companion planting. In this guide, we'll explore the best marigold varieties to plant with tomatoes and why they work so well together.

The Best Marigold Varieties for Companion Planting

French Marigolds (Tagetes patula)

French marigolds are a popular choice for companion planting with tomatoes because they repel pests such as nematodes and whiteflies. These marigolds have small, compact flowers that come in a range of colors, from yellow to orange to red. They bloom throughout the summer and fall, adding a splash of color to your garden.

How French Marigolds Help Tomatoes

French marigolds release a chemical called alpha-terthienyl, which is toxic to certain soil-borne pathogens that attack tomato plants. This chemical helps to protect the tomatoes from diseases such as Fusarium wilt and root-knot nematodes. Additionally, the strong scent of marigolds repels whiteflies, which can damage tomato plants by sucking out the sap.

African Marigolds (Tagetes erecta)

African marigolds are another popular variety for companion planting with tomatoes. These marigolds have large, showy flowers that come in a range of colors, from white to yellow to orange. They bloom throughout the summer and fall, providing a bright pop of color to your garden.

How African Marigolds Help Tomatoes

African marigolds are known for their ability to repel root-knot nematodes, which can cause stunted growth and reduced yields in tomato plants. These marigolds also produce a chemical called thiophene, which is toxic to certain soil-borne pathogens that attack tomato plants. Additionally, the strong scent of marigolds repels other pests such as aphids and spider mites.

How to Plant Marigolds with Tomatoes

When planting marigolds with tomatoes, it's important to choose the right variety and to plant them in the right location. Here are some tips to help you get ed:
