Edible gardening is a rewarding endeavor, and growing tomatoes is often at the top of the list for many gardeners. However, tomato plants are frequently plagued by pests such as tomato hornworms. Fortunately, companion planting offers a natural and effective solution to keep these common tomato pests at bay.
Companion planting is the practice of growing different plants together for mutual benefit. When it comes to tomatoes, there are several top companion plants that can help discourage pests. These include a variety of herbs, vegetables, and flowers.
Basil: The Aromatic Defender
Basil is one of the most well - known tomato companion plants. Its strong aroma acts as a natural deterrent to many pests that target tomatoes. The scent of basil can mask the smell of tomatoes, making it harder for pests like tomato hornworms to locate them. Additionally, basil and tomatoes seem to enhance each other's growth and flavor. When planted side by side, the tomatoes often taste sweeter, and the basil grows more vigorously. You can plant basil directly in the soil around your tomato plants or in containers nearby. Just make sure it gets enough sunlight, as both basil and tomatoes thrive in full - sun conditions.
Marigolds: The Colorful Protectors
Marigolds are not only beautiful but also highly beneficial for tomato plants. They release a chemical from their roots that repels nematodes, which are microscopic worms that can damage tomato roots. Marigolds also attract beneficial insects such as ladybugs and lacewings. These insects prey on aphids, which are another common pest of tomato plants. You can plant marigolds around the perimeter of your tomato patch or intersperse them among the tomato plants. Their bright orange and yellow flowers will add a splash of color to your garden while protecting your tomatoes.
Sunflowers: The Tall Guardians
Sunflowers are tall and imposing plants that can provide shade and support for tomato plants. They also attract birds, which feed on many of the insects that harm tomatoes. The large flower heads of sunflowers act as a landing pad for beneficial insects, and the seeds are a favorite food of birds. By attracting birds to your garden, you can reduce the population of pests like caterpillars and beetles. Plant sunflowers at the north side of your tomato patch so they don't shade the tomatoes too much during the day. As the sunflowers grow, they can also serve as a natural trellis for the tomato vines to climb.
Nasturtiums: The Edible Defenders
Nasturtiums are edible flowers that are also great companions for tomatoes. They attract aphids away from the tomato plants. Aphids are attracted to the bright colors and strong scent of nasturtiums. Once the aphids are on the nasturtiums, they can be easily removed or controlled. Nasturtiums also have a peppery taste, which some pests find unappealing. You can plant nasturtiums around the base of your tomato plants or in hanging baskets near the tomato patch. Their colorful flowers will add a decorative touch to your garden, and you can even use the leaves and flowers in salads.
Garlic: The Pungent Protector
Garlic is a powerful companion plant for tomatoes. Its strong smell repels many pests, including spider mites and aphids. Garlic also has antifungal properties, which can help prevent diseases in tomato plants. Plant garlic cloves around the tomato plants in the early spring. As the garlic grows, it will release its pungent odor, creating a protective barrier around the tomatoes. You can harvest the garlic bulbs later in the season, and enjoy the added benefit of having fresh garlic for cooking.
In conclusion, companion planting is a simple and eco - friendly way to protect your tomato plants from pests. By incorporating these top tomato companion plants - basil, marigolds, sunflowers, nasturtiums, and garlic - into your vegetable garden, you can create a healthy and thriving environment for your tomatoes. Not only will you reduce the need for chemical pesticides, but you'll also enjoy a more diverse and beautiful garden. So, the next time you plant tomatoes, don't forget to invite their secret allies to the party!
