What Not to Plant Next to Potatoes

As a staple in many diets around the world, potatoes are a popular crop for home gardeners. However, there are some plants that should not be planted next to potatoes. In this article, we will discuss some of the plants that should be avoided to ensure a successful potato harvest.

1. Tomatoes

While tomatoes and potatoes are part of the same family, they should not be planted near each other. This is because they are susceptible to many of the same diseases, such as blight. If one plant becomes infected, it can quickly spread to the other. Additionally, they both require similar nutrients from the soil, so planting them together can lead to competition for these nutrients.

2. Cucumbers

Cucumbers are another plant that should not be planted next to potatoes. Cucumbers require a similar soil pH as potatoes, but they have different nutrient requirements. This means that if they are planted together, they will both compete for the same nutrients, leading to stunted growth and lower yields for both plants. Additionally, cucumbers can attract cucumber beetles, which can spread bacterial wilt to potatoes.

3. Squash

Squash, such as zucchini and pumpkins, should not be planted near potatoes. This is because these plants can attract squash bugs, which can spread bacterial wilt to potatoes. Additionally, squash and potatoes both require a lot of space to grow. Planting them too close together can lead to overcrowding and disease issues.

4. Other Members of the Nightshade Family

Potatoes are part of the Solanaceae or nightshade family, which includes plants like peppers, eggplants, and tobacco. While they can be planted near each other, it is important to rotate crops to prevent disease buildup in the soil. This means that potatoes should not be planted in the same spot where nightshades were planted the previous year.

5. Fennel

Fennel is another plant that should not be planted near potatoes. Fennel can attract a pest called the potato aphid, which can damage the potato plant and reduce yields. Additionally, fennel can produce a toxin that can stunt the growth of nearby plants.

In conclusion, there are several plants that should not be planted next to potatoes. Tomatoes, cucumbers, squash, other members of the nightshade family, and fennel can all lead to disease and pest issues for potatoes. It is important to rotate crops and plant companions that can help to deter pests and improve soil health. By following these guidelines, you can ensure a bountiful potato harvest.
