Basil is a well-loved companion for tomatoes because they're like family in the plant world. This aromatic herb has a sweet and strong taste that makes tomato dishes taste even better. Basil can boost how well tomatoes grow and give you more of them to enjoy. Plus, it's not a favorite snack for some pesky bugs like aphids, spider mites, and whiteflies.



Amaranth is a wonderful companion for tomatoes. This tough plant, sometimes called Chinese Spinach, is not only nutritious but also perfect for salads and stir-fries. It grows fast and doesn't mind the heat, which makes it a perfect partner for tomatoes. Plus, it's tall enough to give your tomato plants some shade when the sun gets too intense.


Chives make a fantastic partner for your tomato plants. They're like little pest bouncers, keeping aphids, spider mites, and other tiny bugs away. Plus, they add a tasty onion-like smell to your tomatoes. But that's not all! Chives also give your soil a nitrogen boost, which helps your plants grow strong and healthy. Planting chives with your tomatoes not only makes them taste better but also keeps those pesky pests at bay.

French Marigolds

Marigolds are a top pick for keeping tomatoes safe. They send pests like root-knot nematodes and certain beetles packing. Plus, their smell keeps away other pesky insects like whiteflies. Planting marigolds near your tomatoes not only shields them from pests but also adds vibrant colors to your garden.


Nasturtiums are like the sunshine of your garden, bright and beautiful, and they're perfect pals for tomatoes. Not only do they look lovely, but they also send pests running away from your tomato plants. What's more, nasturtiums are great at making the soil richer. They give it nitrogen and other important nutrients, making your tomatoes grow strong and healthy.


Dill is a fragrant herb with delicate green leaves that adds a tasty twist to various dishes. But here's the twist: it's not just a flavor enhancer; it's also a fantastic companion for tomatoes.

When you plant dill near tomatoes, it becomes their pest bodyguard, keeping aphids and spider mites away. Its strong aroma even masks the tomato scent, which can confuse and deter some pests. And that's not all! Dill gives the soil a boost by adding nitrogen and other important nutrients, making sure your tomatoes grow healthy and strong.



Thyme, the aromatic herb, is a top pick for keeping tomatoes company. It loves the sun and dry soil, just like tomatoes do. When you plant thyme close to tomatoes, it works its magic by keeping pesky insects away and possibly even adding a little extra flavor to your tomatoes. The strong thyme scent acts like a bug repellent, making life tough for unwelcome guests like whiteflies and aphids. It's a perfect partner for your tomatoes.


Cilantro is like a superhero for your tomato garden. It's a natural pest repellent, keeping aphids, spider mites, and other troublesome bugs away from your tomato plants. It even scares off nematodes, which can harm tomato roots. The fresh aroma of cilantro leaves also covers up the tomato scent, making it less appealing to some insects. Plus, it can give your tomatoes an extra boost in the flavor department. It's a real friend to your tomatoes.


Oregano, the versatile herb, is a perfect match for tomatoes. When they grow side by side, oregano enhances the taste and smell of your tomatoes. It's like a natural seasoning. Plus, it scares away unwanted guests like tomato hornworms and aphids that might bug your tomato plants. And here's a bonus: oregano is also a medicinal powerhouse, helping shield your tomato plants from diseases. 


Carrots and tomatoes are like garden buddies made in heaven. They both love the sun and good soil, so they thrive together. It's not just about looks; carrots can actually make your tomato plants healthier and more productive! Carrots are like the guardians of your tomato patch, keeping away pests like aphids and tomato hornworms. They're a great addition to any tomato garden, making it a win-win partnership.


Garlic and tomatoes are a dynamic duo in the garden. For ages, people have known that planting garlic with tomatoes not only makes them taste better but also keeps them safe. Garlic has special stuff that bugs like aphids hate, and it fights off tomato diseases too. Plus, the sulfur in garlic can make your tomatoes even tastier when they grow side by side. And as a bonus, garlic is like a soil magician, adding important nutrients to your garden's earth. It's a win-win for your tomato patch!


Lettuce and tomatoes make a great team in the garden. You can plant lettuce with tomatoes in the early spring, and as the summer gets hot, the lettuce acts like a natural umbrella, giving some shade to the tomatoes. Lettuce also keeps pesky weeds at bay, and because its roots don't dig deep, they won't fight with the tomato roots for space. Plus, when lettuce grows near tomatoes, it enjoys their nutrient-rich soil, and as a bonus, it can even make your tomatoes taste even better. It's a win-win partnership in your garden!


Petunias are the perfect companion for your tomato plants! These lovely annual flowers add a burst of color to your garden during the summer months. But they're not just a pretty face – they also act as guardians for your tomatoes. Petunias draw in helpful insects like bees and ladybugs, which feast on pesky pests like aphids and mites. And here's a clever trick: petunias release a fragrance that hides the tomato scent, making them less tempting to certain pests. It's like having both a bodyguard and a decorator for your tomato patch!
