Starting a tomatogarden is one of the most rewarding ways to kick off the growing season. Whether you’re planting in raised beds, containers or straight into the ground, tomatoes tend to be the star of the show. But getting those lush vines and juicy fruits isn’t just about sun and water—what you plant around your tomatoes can make a huge difference.

A recent viral Instagram video from @gardenaryco highlights how companion planting can naturally deter pests while improving growth. Instead of relying on sprays or constant intervention, the idea is to build a mini ecosystem where plants support each other. Here are seven companion plants from that video that can help your tomatoes thrive.

7 Perfect Plant Partners for Healthier, Happier Tomatoes

1. Lavender

Lavender isn’t just beautiful—it’s a powerful pest repellent. Its strong scent helps deter mosquitoes, moths and even some beetles that might otherwise target your tomato plants. Plus, it attracts pollinators, which benefits your entire garden.

Beyond pest control, lavender adds a soft pop of purple and a calming fragrance to your garden space. It can also be harvested for dried bundles, sachets or even homemade oils.

2. Marigolds

Marigolds are a classic for a reason. They release compounds into the soil that help repel nematodes and other harmful insects. Gardening experts suggest planting them as a border around tomato beds for maximum effect.

They also bring bright, cheerful color that lasts all season long. Marigolds are easy to grow and make excellent cut flowers for simple, sunny arrangements.

3. Parsley

Parsley works as a subtle helper. It attracts beneficial insects like hoverflies, which feed on aphids—a common tomato pest. It’s a quiet but important addition to your garden mix.

In the kitchen, parsley is incredibly versatile. Freshly snipped, it adds a clean, vibrant flavor to salads, sauces and countless dishes, making it as useful as it is beneficial.

4. Chives

Chives bring a mild onion scent that confuses and repels pests such as aphids and Japanese beetles. They’re also compact, making them perfect for tucking between tomato plants without crowding them.

They also produce delicate purple blooms that are edible and visually striking. Both the greens and flowers can be used to add a mild onion flavor to meals.

5. Basil

Basil is often called the ultimate tomato companion, and for good reason. It may help improve flavor while also repelling flies and hornworms. You can even plant basil directly alongside tomatoes in the same container.

In addition to its garden benefits, basil is a staple in the kitchen—perfect for sauces, pesto, and fresh summer dishes that pair naturally with tomatoes.

6. Peppers

Peppers share similar growing conditions with tomatoes, making them easy neighbors. While they don’t repel pests as strongly as some herbs, they maximize space and create a fuller, more diverse planting area that can reduce pest concentration.

They also add variety and color to your harvest, from sweet bell peppers to spicy varieties, giving you more options for cooking and preserving.

7. Squash

Squash acts as a living ground cover. Its large leaves shade the soil, helping retain moisture and suppress weeds. This creates a healthier environment overall, which supports stronger tomato growth.

As a bonus, squash plants are highly productive and can yield an abundant harvest. Their sprawling vines and bold leaves also give your garden a lush, full appearance.

With the right plant partners, your tomato garden can become more resilient—and a lot more productive.
