Can You Plant Next to Tomatoes?

Tomatoes are one of the most popular vegetables to grow in a home garden. They are relatively easy to cultivate and produce a bountiful harvest. However, not all plants can be grown next to tomatoes. In this article, we will explore which plants can be planted next to tomatoes and which ones should be avoided.

Companions for Tomatoes

There are many plants that can be grown alongside tomatoes that help to improve their growth and health. These plants are known as companion plants. Some of the best companion plants for tomatoes include:

Basil

Carrots

Marigolds

Nasturtiums

Parsley

Basil is a great companion for tomatoes as it repels insects that can harm the plants. Carrots help to aerate the soil, which can improve the growth of tomatoes. Marigolds are a natural pest repellent and can help to keep harmful insects away from your tomato plants. Similarly, nasturtiums can help to deter beetles and other insects that can damage tomato plants. Parsley is a good companion plant as it attracts beneficial insects like hoverflies that can help to pollinate the tomato plants.

Plants to Avoid

Not all plants make good companions for tomatoes. Some plants can actually harm tomatoes by competing for the same nutrients in the soil or by attracting pests. Some of the plants to avoid planting next to tomatoes include:

Corn

Fennel

Nightshade Plants (e.g. peppers, eggplants, potatoes)

Walnuts

Corn and fennel are both heavy feeders and can deplete the nutrients from the soil, making it harder for tomato plants to grow. Nightshade plants, which include peppers, eggplants, and potatoes, are all prone to similar pests and diseases as tomatoes. Planting them next to your tomatoes can create a breeding ground for these pests and diseases. Walnuts release a harmful chemical called juglone, which can be toxic to tomato plants.

Final Thoughts

Planting companion plants alongside your tomatoes can be a great way to improve their growth and health. However, it is important to choose the right plants to avoid harming your tomato plants. By planting basil, carrots, marigolds, nasturtiums, and parsley, you can help to protect your tomato plants from pests and improve their overall growth. Meanwhile, avoiding corn, fennel, nightshade plants, and walnuts can help to prevent competition for soil nutrients and keep your tomato plants healthy.
