Companion planting is an age-old gardening technique that involves planting certain plants together in close proximity to each other in order to create a mutually beneficial relationship between the plants. This practice can help to improve garden biodiversity by attracting beneficial insects, repelling pests, reducing disease, and promoting plant growth.
The Benefits of Companion Planting:
Attracting Beneficial Insects
One of the key benefits of companion planting is that it can help to attract beneficial insects to your garden. Certain plants produce nectar and other attractants that can draw in beneficial insects like ladybugs, lacewings, and pollinators like bees and butterflies. These insects can then help to keep pest populations under control, which can reduce the need for chemical pesticides.
Companion planting can also be used to deter pests from attacking your plants. For example, planting herbs like basil, rosemary, and mint near your vegetables can help to repel aphids, flies, and other common garden pests.
Another benefit of companion planting is that it can help to reduce the spread of disease. By planting different species of plants together, you can reduce the risk of disease spreading from one plant to another. For example, planting onions near your tomatoes can help to prevent the spread of tomato blight.
Promoting Plant Growth
In addition to the benefits mentioned above, companion planting can also help to promote plant growth. Certain plants can improve the soil structure and fertility, which can benefit the plants growing around them. For example, planting legumes like beans and peas can help to fix nitrogen in the soil, making it available for other plants to use.
Common Companion Planting Combinations
There are many different companion planting combinations that can be used to improve garden biodiversity. Some of the most common combinations include:
- Tomatoes and basil
- Carrots and onions
- Cucumbers and sunflowers
- Lettuce and radishes
- Squash and beans
Companion planting is a simple yet effective way to improve garden biodiversity. By planting certain plants together, you can attract beneficial insects, repel pests, reduce disease, and promote plant growth. So why not give it a try in your own garden and see the results for yourself?

Additional Tips for Companion Planting Success
In addition to selecting the right plant combinations, there are a few other factors to consider in order to achieve success with companion planting:
- Space: Make sure to plant your companion plants close enough together so that they can benefit from each other, but not so close that they compete for light, water, and nutrients.
- Soil: Make sure the soil in your garden is healthy and well-draining. Poor soil can lead to a range of problems, including disease, poor plant growth, and reduced pest resistance.
- Water: Make sure to water your plants properly, especially during dry periods. Over-watering or under-watering can both lead to problems.
- Light: Consider the light requirements of each plant when choosing where to plant them. Some plants need full sun, while others do better in partial shade.
By following these tips and selecting the right plant combinations, you can maximize the benefits of companion planting and improve the biodiversity of your garden.
