Yes, you can absolutely plant herbs around tomato plants, and it’s a fantastic idea for several reasons. Companion planting herbs with tomatoes can deter pests, attract beneficial insects, and even improve the flavor of your tomatoes. This practice is a cornerstone of organic gardening and can lead to a healthier, more productive garden.

The Benefits of Planting Herbs Around Your Tomatoes

Companion planting is an age-old gardening technique. It involves strategically placing different plants near each other to provide mutual benefits. When it comes to tomatoes, certain herbs offer a surprising array of advantages.

Pest Deterrence: Keeping the Bad Bugs Away

Many common garden pests dislike the strong scents of certain herbs. Planting these around your tomatoes can create a natural barrier. For instance, basil is renowned for repelling tomato hornworms and whiteflies.

Marigolds are another excellent choice. Their roots release thiophenes, a substance that can deter nematodes in the soil. This helps protect your tomato plant’s root system from these microscopic pests.

Attracting Beneficial Insects: Welcoming the Good Guys

While some herbs deter pests, others attract beneficial insects. These are the good bugs that prey on the pests that damage your tomatoes. For example, dill and parsley attract ladybugs and lacewings, both of which are voracious eaters of aphids.

Borage is a magnet for pollinators like bees. Increased pollination can lead to a better fruit set and larger, more abundant tomatoes. A healthy ecosystem in your garden is key to success.

Improving Tomato Flavor and Growth

Some gardeners swear that certain herbs can actually enhance the flavor of tomatoes. Basil, in particular, is often cited for this benefit. The theory is that the herbs and tomatoes share nutrients and soil conditions, leading to a more robust flavor profile.

Additionally, some herbs can improve soil health. For example, legumes like beans can fix nitrogen in the soil, which is beneficial for heavy feeders like tomatoes. However, focus on herbs for this specific question.

Top Herbs to Plant Near Tomatoes

Not all herbs are created equal when it comes to companion planting with tomatoes. Here are some of the most effective choices:

Basil: The Classic Companion

Basil is perhaps the most well-known herb to plant with tomatoes. It’s believed to repel tomato hornworms, whiteflies, and even flies. Its presence is thought to improve tomato growth and flavor.

• Benefits: Pest deterrence, flavor enhancement.
• Considerations: Basil thrives in similar conditions to tomatoes – warm weather and plenty of sun.

Marigolds: The Nematode Fighter

French marigolds are particularly effective. Their roots release a chemical that kills nematodes, microscopic worms that can damage tomato roots. They also add a splash of color to your garden.

• Benefits: Nematode control, general pest deterrence.
• Considerations: Choose French varieties for the best nematode-fighting results.

Borage: The Pollinator Magnet

Borage is a beautiful herb with edible flowers. It attracts bees and other pollinators, which are crucial for tomato fruit development. It’s also said to deter tomato hornworms and cabbage worms.

• Benefits: Attracts pollinators, deters some pests.
• Considerations: Borage can self-seed, so be mindful of its spread.

Mint: The Powerful Repellent (with a Caveat)

Mint is a strong repellent for many pests, including aphids and flea beetles. However, mint is highly invasive. If you plant it directly in the ground near your tomatoes, it can quickly take over your garden.

• Benefits: Repels aphids, flea beetles, and ants.
• Considerations: Always plant mint in containers to control its spread.

Rosemary: The Deer and Rabbit Deterrent

While deer and rabbits aren’t typically a major threat to tomato plants themselves, they can damage surrounding foliage. Rosemary’s strong scent can deter these larger animals, protecting your entire garden plot.

• Benefits: Deters deer and rabbits.
• Considerations: Rosemary prefers drier conditions than tomatoes, so place it where it won’t be overwatered.

Chives and Garlic: The Allium Allies

Chives and garlic belong to the allium family. Their strong scent can deter aphids and other sap-sucking insects. They also have a reputation for deterring Japanese beetles.

• Benefits: Repels aphids, spider mites, and Japanese beetles.
• Considerations: These are relatively low-maintenance additions.

How to Plant Herbs Around Tomatoes

When planting herbs around your tomato plants, consider spacing and the specific needs of each herb. You want to ensure both plants have adequate room to grow and receive the necessary sunlight and water.

Spacing Considerations

Don’t overcrowd your tomato plants. Give them enough space to breathe and grow. Plant herbs in a circle around the tomato plant, or intersperse them throughout the garden bed.

Aim for a few inches of space between the base of the tomato plant and the nearest herb. This prevents competition for resources and allows for good air circulation.

Watering and Sunlight Needs

Most of the herbs mentioned thrive in similar conditions to tomatoes: full sun and well-draining soil. However, always check the specific requirements for each herb. For example, rosemary prefers drier soil than tomatoes.

If you’re planting mint, remember the container. This ensures its aggressive root system doesn’t harm your tomatoes.

Example Planting Layout

Imagine a central tomato plant. You could plant a cluster of basil to its north, marigolds to its east, and chives to its west. This provides a good mix of benefits without overcrowding.

What Herbs NOT to Plant Near Tomatoes

While many herbs are beneficial, a few can hinder tomato growth. It’s important to know which ones to avoid.

Fennel: The Lone Wolf

Fennel is notorious for inhibiting the growth of many plants, including tomatoes. It releases a chemical called anethole, which can stunt the development of nearby vegetables. It’s best to keep fennel separate from your tomato patch.

Cabbage Family Herbs (like Dill)

While dill can attract beneficial insects, it’s also known to attract cabbage worms. If cabbage worms are a problem in your area, you might want to reconsider planting large amounts of dill near your tomatoes, or be prepared to manage those pests.
