What Not to Plant with Potatoes

When it comes to gardening, some plants just don't make good companions. This is especially true when it comes to growing potatoes in your garden. There are some plants that you should avoid planting with potatoes, either because they can compete for resources, attract pests, or even inhibit the growth of your potatoes. In this article, we'll explore what not to plant with potatoes, so you can maximize your potato harvest.

Companion Plants for Potatoes

Before we dive into what not to plant with potatoes, let's first discuss some companion plants that can benefit your potato plants. Companion planting is the practice of planting different crops in close proximity to each other to take advantage of their mutually beneficial qualities. One common companion plant for potatoes is beans, as they add nitrogen to the soil, which is essential for potato growth. Other beneficial companion plants for potatoes include marigolds, peas, and corn.

What Not to Plant with Potatoes

Now let's discuss what not to plant with potatoes. One plant you should avoid planting with potatoes is tomatoes. While both plants are in the nightshade family, they have different nutrient requirements, and planting them together can lead to competition for resources. Additionally, both plants are susceptible to the same fungal diseases, such as early blight and late blight, which can spread easily if planted together.

Another plant to avoid planting with potatoes is squash. Squash can attract pests, such as squash bugs and squash vine borers, which can also affect the health of your potato plants. Additionally, squash plants are heavy feeders and can compete for soil nutrients with your potato plants.

Finally, it's best to avoid planting potatoes near members of the Brassica family, such as broccoli, cabbage, and cauliflower. These plants release chemicals into the soil that can inhibit the growth of potatoes, leading to stunted or malformed tubers.

Tips for Growing Healthy Potatoes

Now that we've covered what not to plant with potatoes, let's discuss some tips for growing healthy potato plants. First, make sure to plant potatoes in well-draining soil with plenty of organic matter. Potatoes also require regular watering and fertilization throughout the growing season. Additionally, it's important to practice crop rotation and not plant potatoes in the same spot two years in a row, as this can lead to a buildup of pests and diseases in the soil.

In conclusion, growing healthy potatoes involves planting them with the right companion plants and avoiding certain plants that can inhibit their growth or attract pests. While tomatoes, squash, and members of the Brassica family should be avoided when planting potatoes, beans, marigolds, peas, and corn can be beneficial companions. By following these tips and best practices, you can enjoy a bountiful potato harvest.
