What Not to Plant by Tomatoes

Tomatoes are a popular crop for many gardeners. They are delicious and versatile, and their bright red color adds a pop of color to any dish. However, not all plants are good companions for tomatoes. In fact, some plants can actually harm tomatoes, so it's important to choose complementary plants wisely.

Avoid Planting Nightshade Plants Near Tomatoes

Tomatoes belong to the nightshade family, which includes plants such as peppers, eggplants, and potatoes. However, not all nightshade plants make good companions for tomatoes. In particular, it's best to avoid planting other tomato plants, as they can attract pests and spread diseases. Eggplants can also attract pests that feed on tomato plants, so it's best to keep them separate. Potatoes share many of the same pests and diseases as tomatoes, so it's best to rotate them with other crops every few years.

Don't Plant Brassicas Near Tomatoes

Brassicas are a family of plants that includes broccoli, cauliflower, kale, and cabbage. These plants can be beneficial to gardens, as they attract beneficial insects such as ladybugs and lacewings. However, they do not make good companions for tomatoes. Tomatoes and brassicas are both heavy feeders, which means they compete for the same nutrients. Additionally, brassicas are known to attract pests such as aphids, which can damage tomato plants.

Avoid Planting Fennel Near Tomatoes

Fennel is a plant that is often grown for its flavorful seeds or bulbs. However, it's not a good companion for tomatoes. Fennel produces chemicals that can inhibit the growth of tomato plants, particularly when the plants are young. Additionally, fennel can attract pests that can harm tomato plants, such as aphids and whiteflies. If you must plant fennel, it's best to keep it well away from your tomato plants.

Choose Complementary Plants for Tomatoes

While there are many plants that can harm tomatoes, there are also many plants that make great companions for them. Marigolds, for example, are known to repel pests and attract beneficial insects. Basil is also a great companion for tomatoes, as it can improve their flavor and protect them from pests. Other good companions for tomatoes include onions, garlic, and carrots.

Choosing complementary plants for your tomato garden can help you get the most out of your crop. By avoiding harmful plants and choosing beneficial ones, you can ensure that your tomatoes grow strong and healthy, and that you get a bountiful harvest that's full of flavor.
