The best herb to plant with tomatoes is basil. Basil is widely considered the top companion plant for tomatoes due to its ability to deter pests like tomato hornworms and whiteflies, while also enhancing tomato flavor.

Why Basil is the Top Herb for Tomato Companionship

When you’re planning your summer garden, the question of what to plant alongside your precious tomato seedlings often arises. While many herbs offer benefits, basil consistently emerges as the premier choice for a reason. Its synergistic relationship with tomatoes goes beyond mere proximity, offering tangible advantages for both plant health and yield.

Enhancing Tomato Flavor and Growth

Many gardeners swear that planting basil near their tomatoes not only keeps pests away but also improves the taste of the tomatoes. While scientific evidence for flavor enhancement is anecdotal, the positive impact on plant health is undeniable. Healthy plants often produce more flavorful produce.

Deterring Common Tomato Pests

One of basil’s most celebrated roles is as a natural pest repellent. Its strong aroma is particularly effective against common garden nuisances that plague tomato plants.

• Tomato Hornworms: These large, voracious caterpillars can decimate a tomato plant overnight. Basil’s scent is believed to confuse or deter them.
• Whiteflies: These tiny, sap-sucking insects can weaken plants and spread disease. Basil’s fragrance can make it harder for whiteflies to locate their host plants.
• Aphids: While basil may not completely eliminate aphids, it can help to reduce their numbers, preventing significant damage.

Which Basil Varieties Work Best?

While most basil varieties will offer some benefit, certain types are particularly well-suited for companion planting with tomatoes.

Beyond Basil: Other Beneficial Herbs for Tomatoes

While basil reigns supreme, several other herbs can also be excellent companions for your tomato plants, offering a diverse range of benefits.

Mint: A Potent Pest Repellent

Mint, with its vigorous growth, can be a powerful deterrent for many garden pests. However, it’s crucial to plant mint in containers or with root barriers. Its invasive nature can quickly take over your garden beds.

• Pest Control: Mint is known to repel aphids, ants, and even some rodents.
• Growth Habit: Container planting is highly recommended to prevent it from spreading aggressively.

Rosemary: A Hardy Protector

Rosemary is a robust herb that can also contribute to a healthier tomato patch. Its strong scent can mask the tomato plants’ scent, making them less attractive to certain pests.

• Pest Deterrence: Effective against some flying insects and beetles.
• Drought Tolerance: Rosemary thrives in similar conditions to tomatoes, making it an easy companion.

Chives and Garlic: Allium Allies

Members of the allium family, like chives and garlic, are fantastic for repelling pests. Their strong odor is a natural deterrent for a wide array of garden invaders.

• Pest Repellent: Particularly effective against aphids and spider mites.
• Soil Health: Some gardeners believe they can improve soil quality.

Herbs to Avoid Planting Near Tomatoes

While many herbs are beneficial, some can hinder tomato growth or attract unwanted pests. It’s wise to keep certain plants separated from your tomato patch.

• Fennel: Fennel is known to inhibit the growth of many plants, including tomatoes. It’s best to give it its own space.
• Cabbage Family (Broccoli, Cabbage, Kale): These plants can attract specific pests that may also affect tomatoes or compete for nutrients.
• Corn: Corn attracts the corn earworm, which can easily transfer to tomato plants.
