Companion planting is the practice of growing different plants together for mutual benefit. The benefits of companion planting can include:
- Reduced pest and disease pressure. Some companion plants have natural insecticidal or repellent properties that can help to deter pests from attacking your other plants. For example, marigolds are a popular companion plant for tomatoes because they help to repel nematodes, which can damage tomato roots.
- Improved pollination. Some companion plants attract beneficial insects, such as bees and butterflies, which help to pollinate your other plants. This can lead to increased yields and better quality fruits and vegetables.
- Improved soil health. Some companion plants help to improve the soil structure and fertility, which can benefit all of the plants in your garden. For example, legumes, such as peas and beans, fix nitrogen in the soil, which can be used by other plants.
- More efficient use of space. Companion planting can help you to maximize the space in your garden by planting different plants that have different requirements. For example, you can plant tall plants, such as sunflowers, to provide shade for shorter plants, such as lettuce.

Examples of Companion Plants

- Beans and tomatoes: Beans fix nitrogen in the soil, which can benefit tomatoes. Tomatoes provide shade for beans, which can help to prevent them from bolting.
- Carrots and onions: The strong smell of onions helps to repel carrot root fly, which can damage carrots. Carrots help to improve the flavor of onions.
- Cucumbers and melons: Cucumbers and melons need a lot of water, so planting them together can help to conserve water. Cucumbers also help to shade melons, which can help to prevent them from sunburning.
- Lettuce and spinach: Lettuce and spinach grow well in the same conditions, so they can be planted together to save space. Lettuce also helps to shade spinach, which can help to prevent it from bolting.
- Marigolds and roses: Marigolds help to repel aphids, which can damage roses. Marigolds also help to improve the drainage around roses, which can help to prevent root rot.
