Companion planting is a gardening technique where different plants are grown together to enhance their growth and repel pests. In this article, we will explore some of the best companion plants for watermelon in 2023.

1. Nasturtium

Nasturtium is a great companion plant for watermelon as it acts as a natural repellent for pests like aphids, squash bugs, and beetles. Its vibrant flowers also attract pollinators, which can help in better fruit set for watermelon. Nasturtium also acts as a ground cover, preventing weed growth and conserving soil moisture.

2. Marigold

Marigold is another excellent companion plant for watermelon. Its strong aroma deters pests like nematodes, beetles, and aphids. Marigold also attracts beneficial insects like ladybugs and lacewings, which feed on pests that can harm watermelon plants. Additionally, marigold flowers add a pop of color to your garden.

3. Radish

Planting radish alongside watermelon can provide several benefits. Radishes act as a trap crop, attracting root maggots away from watermelon roots. They also help in loosening the soil with their long taproots, improving watermelon’s access to nutrients and water. Radish leaves can be used as a natural mulch to conserve soil moisture.

4. Beans

Beans, such as bush beans or pole beans, can be grown as companion plants for watermelon. They are nitrogen-fixing plants, which means they can convert atmospheric nitrogen into a form that is usable by plants. Watermelon plants require a good amount of nitrogen for healthy growth, and beans can provide it naturally. Additionally, the sprawling vines of beans can provide shade and reduce weed growth around watermelon plants.

5. Mint

Mint is a fragrant herb that can repel pests like ants, aphids, and flea beetles. Planting mint near watermelon can help in keeping these pests away. However, it is important to contain mint’s growth as it can become invasive. Planting mint in a container or using a barrier around its roots can prevent it from taking over your garden.
