What Other Vegetables Should I Not Plant Near My Tomatoes?

Planting vegetables together in a garden can be a great way to save space and increase yields, but not all vegetables get along. In fact, some vegetables can have a negative impact on the growth and health of others. Tomatoes, in particular, can be sensitive to certain plants, so it's important to know what to avoid planting near them. Here are some vegetables you should not plant near your tomatoes:

Potatoes

One vegetable that should not be planted near tomatoes is potatoes. Both plants are in the nightshade family, and they can both attract the same diseases and pests. Planting potatoes near tomatoes can increase the risk of blight, which can cause leaves to yellow and die, and reduce fruit production. Additionally, potatoes can also compete with tomatoes for nutrients and water, leading to stunted growth for both plants.

Cucumbers

While it may seem like a good idea to plant cucumbers near your tomatoes to make use of vertical space, it's actually not recommended. Cucumbers are heavy feeders and can deplete the soil of nutrients quickly, leaving little for the tomatoes. Additionally, cucumbers attract many of the same pests as tomatoes, including aphids and spider mites. Planting them together can increase the risk of infestations for both plants.

Brassicas

Brassicas such as broccoli, cabbage, and cauliflower should not be planted near tomatoes. Brassicas are known to release compounds that can inhibit the growth of tomatoes and other plants in the nightshade family, such as peppers and eggplants. Additionally, they can attract the same pests as tomatoes, such as cutworms and flea beetles.

Fennel

Fennel is a unique plant that can provide a lot of benefits in the garden, including attracting beneficial insects such as ladybugs and lacewings. However, it should not be planted near tomatoes. Fennel secretes chemicals that can inhibit the growth of many plants, including tomatoes. Additionally, fennel can attract the tomato hornworm, a common pest that can devastate a tomato plant in a matter of days.

Conclusion

Knowing what vegetables should not be planted near your tomatoes can help you plan your garden more effectively and avoid potential problems. By avoiding potato, cucumber, brassica, and fennel, you can help ensure that your tomato plants are healthy and productive. Remember to keep a close eye on your plants throughout the growing season and take action if you notice any signs of disease or infestation.
