Gardeners around the world are always looking for ways to enhance the beauty and health of their gardens. One way to do so is by planting marigold companion plants. Marigolds are not only beautiful but also have several benefits for other plants when planted alongside them. In this article, we will explore the benefits of marigold companion plants, how to choose the right marigolds for your garden, and tips for planting them.

Benefits of Marigold Companion Plants

One of the most significant benefits of marigold companion plants is their ability to repel pests naturally. Marigolds contain a compound called alpha-terthienyl that repels nematodes, aphids, whiteflies, and other pests that can damage your plants. By planting marigolds near other plants, you can create a barrier that keeps pests away from your garden.

Another benefit of marigold companion plants is their ability to attract beneficial insects. Ladybugs, lacewings, and hoverflies are insects that feed on harmful pests like aphids and mites. By planting marigolds alongside other plants, you can attract these beneficial insects to your garden, which will help keep pests under control.

Finally, marigolds are also known to improve soil health. They release a chemical called alpha-terpinene, which suppresses harmful soil-borne pathogens like Fusarium and Pythium. Marigolds can also help improve soil structure and fertility by increasing the population of beneficial microorganisms like earthworms.

Choosing the Right Marigolds

When it comes to choosing marigolds for your garden, there are several factors to consider. Firstly, you need to choose the right species of marigold. French marigolds (Tagetes patula) are the most common type of marigold used as companion plants, but you can also use African marigolds (Tagetes erecta) or signet marigolds (Tagetes tenuifolia).

Secondly, you need to choose the right cultivar. Some cultivars of marigolds are better at repelling pests than others. For example, the 'Lemon Gem' cultivar of French marigold is known to be particularly effective against nematodes.

Finally, you need to consider the color and size of the marigold flowers. While marigolds come in a range of colors, including yellow, orange, and red, not all colors are equally effective at repelling pests. Yellow and orange flowers are the most effective, while red flowers are less effective. Additionally, you need to consider the size of the marigold flowers. Smaller flowers are better suited for planting alongside smaller plants, while larger flowers are better suited for larger plants.

Planting Marigold Companion Plants

Now that you have chosen the right marigolds for your garden, it's time to plant them. Here are some tips for planting marigold companion plants:

1. Prepare the Soil

Before planting, make sure that the soil is well-drained and fertile. Remove any weeds or debris from the area where you plan to plant the marigolds.

2. Plant the Marigolds

Dig a hole for each marigold plant that is roughly the same size as the root ball. Place the plant in the hole and cover it with soil. Space the plants at least 6 inches apart, so they have room to grow.

3. Water the Plants

Water the plants thoroughly after planting. Marigolds prefer moist soil but can be prone to root rot if the soil is too wet. Water the plants when the top inch of soil feels dry.

4. Care for the Plants

Marigolds are relatively low maintenance, but they do require some care. Deadhead the flowers regularly to encourage more blooms. Fertilize the plants once a month with a balanced fertilizer.

Companion Plants for Marigolds

While marigolds make great companion plants, they also benefit from having other plants around them. Here are some companion plants that work well with marigolds:

1. Tomatoes

Tomatoes and marigolds make an excellent companion planting combination. Marigolds repel nematodes, which can damage tomato roots, while tomatoes provide shade for the marigolds.

2. Cucumbers

Cucumbers and marigolds also work well together. Marigolds repel cucumber beetles, which can damage cucumber plants.

3. Peppers

Peppers and marigolds make a great pairing. Marigolds repel aphids, which can damage pepper plants.

4. Beans

Beans and marigolds are also a good combination. Marigolds repel bean beetles, which can damage bean plants. Beans also fix nitrogen in the soil, which benefits the marigolds.

5. Herbs

Many herbs, such as basil, parsley, and thyme, make great companion plants for marigolds. Herbs attract beneficial insects and can help repel pests.
