What can you not plant next to tomatoes

Tomatoes are a popular fruit that is grown by many home gardeners. Growing tomatoes can be a fun and rewarding experience, but it is important to remember that tomatoes should not be planted near certain plants. This article will explore the plants that should not be planted next to tomatoes, and why.

Plants to avoid planting near tomatoes

Tomatoes should not be planted near plants that are susceptible to the same diseases and pests. Some of the plants that should not be planted near tomatoes include:

Potatoes

Peppers

Eggplants

Tomatillos

Petunias

Walnuts

Brassicas (broccoli, cauliflower, cabbage)

These plants can attract pests and diseases that can harm tomatoes. For example, potatoes and tomatoes are both in the same family, and they are susceptible to the same diseases, such as blight. Planting them next to each other can increase the risk of disease spreading. Peppers, eggplants, and tomatillos can attract the same pests as tomatoes, including aphids, spider mites, and whiteflies.

Why you should not plant certain plants near tomatoes

Planting certain plants next to tomatoes can stunt their growth and reduce their yield. For example, planting tomatoes near walnuts can result in reduced growth and yield due to a toxic substance called juglone that is released by the roots of the walnut tree. Petunias can also release chemicals that can stunt the growth of tomatoes.

Brassicas, such as broccoli and cauliflower, can compete for nutrients with tomatoes. These plants have a high demand for certain nutrients and can leave tomatoes lacking in those nutrients, which can result in poor growth and yield.

What to plant near tomatoes

Now that you know which plants to avoid planting near tomatoes, you may be wondering which plants are safe to plant near them. Here are some plants that can be planted near tomatoes:

Basil

Parsley

Marigolds

Nasturtiums

Carrots

Garlic

Onions

Lettuce

Basil, parsley, and marigolds can attract beneficial insects that can help control pests that commonly affect tomatoes. Nasturtiums can attract aphids away from tomatoes. Carrots, garlic, onions, and lettuce have a low nutrient demand and can complement the nutrient needs of tomatoes.
