2. When deciding what not to plant near tomatoes, keep in mind that they shouldn’t be planted close to members of the Brassicaceae family, such as broccoli, cauliflower, and cabbage. These plants can attract similar pests and diseases, increasing the risk of infestations and reducing the overall yield of your tomato plants.

3. One surprising companion plant to avoid near tomatoes is corn. While corn can provide some shade to tomato plants, their growth patterns are quite different. Corn grows tall and can cast shadows that stunt the growth of neighboring tomato plants, leading to decreased fruit production.

4. Beware of planting potatoes near your tomatoes! Both plants are susceptible to late blight, a devastating fungal disease that can quickly spread between them. To avoid this, it is advised to separate these crops and provide proper spacing to ensure good air circulation and minimize the risk of infection.

5. While basil is often recommended as a companion plant for tomatoes, it’s important to note that not all basil varieties are suitable partners. Spicy Globe basil, for instance, can negatively affect the growth and flavor of nearby tomatoes. Opt for sweet basil varieties such as Genovese or Italian Large Leaf to enjoy the benefits of this popular pairing.

Cabbage And Corn: Tomato Incompatible Plantings

When it comes to planting tomatoes, it is essential to be aware of the plants that can hinder their growth. One such example is cabbage. While cabbage is a popular vegetable known for its nutritional value, it should not be planted near tomato plants. Cabbage and tomatoes belong to the same plant family, Brassicaceae, and can be susceptible to similar diseases and pests. Planting these two together increases the risk of cross-contamination and can negatively impact the health of both plants.

Similarly, corn is another plant that should not be planted near tomatoes. Corn has a high demand for nutrients, especially nitrogen, and can deplete the soil of essential resources that tomatoes also require. Additionally, the tall stalks of corn can overshadow the tomato plants, depriving them of much-needed sunlight. Therefore, to ensure the optimal growth and yield of your tomato plants, it is best to keep them separate from cabbage and corn.

Broccoli And Fennel: Avoid These Near Tomato Plants

Broccoli, a cruciferous vegetable, is not a compatible companion for tomato plants. Both broccoli and tomatoes are heavy feeders and have similar nutritional requirements. Planting them near each other leads to fierce competition for nutrients, resulting in stunted growth and diminished yields for both crops.

Fennel, with its aromatic and flavorful leaves and seeds, may be a wonderful addition to many dishes. However, it is not recommended to plant fennel near tomato plants. Fennel is known to emit a chemical called anethole, which can negatively impact the growth and development of tomatoes. The emissions of fennel can interfere with the natural growth processes of tomatoes, leading to reduced productivity.

Dill And Potatoes: Not Compatible With Tomatoes

Dill, a popular herb with a distinct flavor, is often used in pickling and seasoning. However, it is best to avoid planting dill near tomato plants. Dill and tomatoes are incompatible due to their similar growth habits and nutrient requirements. Both plants have a tendency to attract aphids and other pests, increasing the risk of infestation when grown together. Moreover, planting dill near tomatoes can result in reduced air circulation, which can contribute to the development of fungal diseases.

Potatoes, a staple crop in many households, should also not be planted near tomatoes. Both potatoes and tomatoes are susceptible to a shared set of diseases, including blight. When planted together, these diseases can spread rapidly, making it challenging to control and prevent their progression. Furthermore, tomatoes and potatoes have similar nutrient requirements. Planting them together can result in nutrient imbalances and deficient growth for both crops.

To summarize:

  • Avoid planting dill near tomatoes to prevent infestation and fungal diseases.
  • Do not plant potatoes near tomatoes to control the spread of diseases.
  • Proper spacing between crops is essential to ensure optimal air circulation.
  • Be mindful of nutrient requirements to avoid imbalances and deficient growth.

Eggplant And Walnuts: Plants To Keep Away From Tomatoes

Growing tomatoes near eggplants can be a risky venture. Both plants are members of the Solanaceae family and are susceptible to similar diseases, such as verticillium wilt and fusarium wilt. Planting them together can create an environment conducive to the spread of these diseases, causing significant damage to both crops.

Walnut trees, while producing delicious nuts, release a chemical compound called juglone. This compound can be toxic to many plants, including tomatoes. Planting tomatoes near walnut trees or any area with juglone exposure can result in stunted growth, wilting, and overall poor health. Therefore, it is advisable to keep tomato plants at a safe distance from walnut trees.

Cauliflower: Best To Keep Separate From Tomato Plants

Cauliflower is not considered a suitable companion for tomato plants. Both cauliflower and tomatoes have similar growth requirements and are vulnerable to similar diseases. Planting them adjacent to one another can increase the risk of fungal infections and pest infestations. Additionally, cauliflower plants tend to have broad leaves that can overshadow and hinder the growth of tomato plants, limiting their access to sunlight.

In contrast, there are certain plants that can be beneficial when grown near tomatoes. These companion plants can aid in pest control, enhance soil fertility, and improve the flavor of tomatoes. Some examples include asparagus, chives, onions, lettuce, marigolds, and basil. Including these plants in your tomato garden can create a harmonious and mutually beneficial environment for your crops.

In summary, careful consideration of companion planting is crucial for tomato plants. Avoid planting cabbage, corn, broccoli, fennel, dill, potatoes, eggplant, walnuts, and cauliflower near tomatoes to ensure optimal growth and productivity. By selecting suitable companion plants and avoiding incompatible ones, you can create a thriving tomato garden that yields bountiful and delicious fruits.
