Can You Plant Potatoes Next to Tomatoes?

Potatoes and tomatoes are often grown in the same garden, but can they be planted next to each other? The answer is somewhat complicated, but it is generally recommended to keep potatoes and tomatoes at least 4 feet apart. This is because both plants are susceptible to similar soil-borne diseases and pests.

The Risks of Planting Potatoes and Tomatoes Next to Each Other

Tomatoes are susceptible to a disease called early blight, which can also affect potatoes. Early blight can cause yellowing and withering of leaves and can ultimately lead to death of the plant. Similarly, potatoes can be affected by a disease called late blight, which can also infect tomatoes. Late blight can cause darkening and rotting of the stems and leaves, and can ultimately lead to the death of the plant.

Another risk of planting potatoes and tomatoes next to each other is that they attract similar pests. For example, potato beetles are a common pest that can be attracted to both potatoes and tomatoes. These beetles lay their eggs on the undersides of leaves and can cause significant damage to both plants if not controlled.

Benefits of Planting Potatoes and Tomatoes Together

Despite the risks, there are some benefits to planting potatoes and tomatoes together. For example, both plants are heavy feeders and can benefit from the same fertilizers and soil amendments. Additionally, planting potatoes and tomatoes in the same garden can help to reduce the occurrence of weeds and other pests.

Furthermore, planting potatoes and tomatoes together can also improve soil health. Potatoes and tomatoes are part of different families of plants, which means that they have different nutrient requirements. As a result, planting these two plants together can help to create a more diverse and balanced soil ecosystem.

Tips for Planting Potatoes and Tomatoes Together

If you decide to plant potatoes and tomatoes together, there are some tips to follow to maximize your chances of success. First, make sure to plant each plant at the appropriate depth – potatoes should be planted about 6 inches deep while tomatoes should be planted about 2 inches deep. Additionally, make sure to rotate your crops every year to help prevent soil-borne diseases from building up over time.

Finally, consider planting other plants in between your potatoes and tomatoes to help reduce the risk of disease and pests. For example, marigolds are a natural pest repellent and can help to keep pests away from both potatoes and tomatoes. Onions and garlic are also good choices as they can help to repel pests and improve soil health.

In Conclusion

In general, it is not recommended to plant potatoes and tomatoes next to each other due to the risk of disease and pests. However, if you do decide to plant these two plants together, be sure to follow these tips to maximize your chances of success and improve soil health.
